cab02463ec Remove prebuild dependency
Every CI build task tagged with 'package' now populates and
publishes the relevant npm/platform directory as an artefact.
These are aggregated by a fan-in release task at the end to
create a complete npm workspace zipfile. If the commit is
tagged, a release is created and the npm workspace attached.

This partially reverts commit 51e56f994ce1332f77daf625e23820a895de074d.

Ignoring plug'n'play, it looks like yarn and pnpm do get the
filesystem layout right for this scenario, which is good news.

It also looks like npm 10 will get it right too.

This reverts commit 3f54ef7525ed357ce64bf375ef7ce3d70a52ba61.

The filesystem layout used by pnpm means that a nesting of 2
directories deep is used in the wild and must remain.

29a83250a4 CI: Add smoke test for npm-published package
These tests will fail on their first run as a tag will exist but
the matching packages will not yet have been published.

The workflow can be manually re-run after publishing to npm.

Eventually, when there's some form of automated publishing, this
logic can become part of the post-publish checks.

f7da2e5970 Building from source now requires node-addon-api in dependencies
If you want to build sharp from source against a globally-installed
libvips then you will now need to add both node-addon-api and
node-gyp to the dependencies section of your package.json file.

The binding.gyp file is "hidden" inside the src directory to
prevent various build and package manager tooling from assuming
that everyone is going to build from source every time.

### Does this problem relate to file caching?
The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.
- [ ] Adding `sharp.cache(false)` does not fix this problem.
### Does this problem relate to images appearing to have been rotated by 90 degrees?
Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).
- [ ] Using `rotate()` or `keepExif()` does not fix this problem.

# Installation
```sh
npm install sharp
```
```sh
yarn add sharp
```
## Prerequisites
* Node.js >= 14.15.0
## Prebuilt binaries
Ready-compiled sharp and libvips binaries are provided for use on the most common platforms:
* macOS x64 (>= 10.13)
* macOS ARM64
* Linux x64 (glibc >= 2.17, musl >= 1.1.24, CPU with SSE4.2)
* Linux ARM64 (glibc >= 2.17, musl >= 1.1.24)
* Windows x64
* Windows x86
A ~7MB tarball containing libvips and its most commonly used dependencies
is downloaded via HTTPS, verified via Subresource Integrity
and decompressed into `node_modules/sharp/vendor` during `npm install`.
This provides support for the
JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
The following platforms have prebuilt libvips but not sharp:
* Linux ARMv7 (glibc >= 2.28)
* Linux ARMv6 (glibc >= 2.28)
* Windows ARM64
The following platforms require compilation of both libvips and sharp from source:
* Linux x86
* Linux ARMv7 (glibc <= 2.27, musl)
* Linux ARMv6 (glibc <= 2.27, musl)
* Linux PowerPC
* FreeBSD
* OpenBSD
## Common problems
The architecture and platform of Node.js used for `npm install`
must be the same as the architecture and platform of Node.js used at runtime.
See the [cross-platform](#cross-platform) section if this is not the case.
When using npm v6 or earlier, the `npm install --unsafe-perm` flag must be used when installing as `root` or a `sudo` user.
When using npm v7 or later, the user running `npm install` must own the directory it is run in.
The `npm install --ignore-scripts=false` flag must be used when `npm` has been configured to ignore installation scripts.
Check the output of running `npm install --verbose --foreground-scripts sharp` for useful error messages.
## Apple M1
Prebuilt sharp and libvips binaries have been provided for macOS on ARM64 since sharp v0.29.0.
## Cross-platform
At `npm install` time, prebuilt binaries are automatically selected for the
current OS platform and CPU architecture, where available.
The target platform and/or architecture can be manually selected using the following flags.
```sh
npm install --platform=... --arch=... --arm-version=... sharp
```
* `--platform`: one of `linux`, `darwin` or `win32`.
* `--arch`: one of `x64`, `ia32`, `arm` or `arm64`.
* `--arm-version`: one of `6`, `7` or `8` (`arm` defaults to `6`, `arm64` defaults to `8`).
* `--libc`: one of `glibc` or `musl`. This option only works with platform `linux`, defaults to `glibc`
* `--sharp-install-force`: skip version compatibility and Subresource Integrity checks.
These values can also be set via environment variables,
`npm_config_platform`, `npm_config_arch`, `npm_config_arm_version`, `npm_config_libc`
and `SHARP_INSTALL_FORCE` respectively.
For example, if the target machine has a 64-bit ARM CPU and is running Alpine Linux,
use the following flags:
```sh
npm install --arch=arm64 --platform=linux --libc=musl sharp
```
If the current machine is Alpine Linux and the target machine is Debian Linux on x64 cpu,
use the following flags:
```sh
npm install --arch=x64 --platform=linux --libc=glibc sharp
```
Multiple platforms and architectures can be supported within the same installation tree.
The following example for macOS installs x64 binaries then adds (via a rebuild) arm64 binaries:
```sh
npm install --platform=darwin --arch=x64 sharp
npm rebuild --platform=darwin --arch=arm64 sharp
```
## Custom libvips
To use a custom, globally-installed version of libvips instead of the provided binaries,
make sure it is at least the version listed under `config.libvips` in the `package.json` file
and that it can be located using `pkg-config --modversion vips-cpp`.
For help compiling libvips and its dependencies, please see
[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
The use of a globally-installed libvips is unsupported on Windows
and on macOS when running Node.js under Rosetta.
## Building from source
This module will be compiled from source at `npm install` time when:
* a globally-installed libvips is detected (set the `SHARP_IGNORE_GLOBAL_LIBVIPS` environment variable to skip this),
* prebuilt sharp binaries do not exist for the current platform, or
* when the `npm install --build-from-source` flag is used.
Building from source requires:
* C++11 compiler
* [node-gyp](https://github.com/nodejs/node-gyp#installation) and its dependencies
## Custom prebuilt binaries
This is an advanced approach that most people will not require.
### Prebuilt sharp binaries
To install the prebuilt sharp binaries from a custom URL,
set the `sharp_binary_host` npm config option
or the `npm_config_sharp_binary_host` environment variable.
To install the prebuilt sharp binaries from a directory on the local filesystem,
set the `sharp_local_prebuilds` npm config option
or the `npm_config_sharp_local_prebuilds` environment variable.
URL example:
if `sharp_binary_host` is set to `https://hostname/path`
and the sharp version is `1.2.3` then the resultant URL will be
`https://hostname/path/v1.2.3/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
Filename example:
if `sharp_local_prebuilds` is set to `/path`
and the sharp version is `1.2.3` then the resultant filename will be
`/path/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
### Prebuilt libvips binaries
To install the prebuilt libvips binaries from a custom URL,
set the `sharp_libvips_binary_host` npm config option
or the `npm_config_sharp_libvips_binary_host` environment variable.
To install the prebuilt libvips binaries from a directory on the local filesystem,
set the `sharp_libvips_local_prebuilds` npm config option
or the `npm_config_sharp_libvips_local_prebuilds` environment variable.
The version subpath and filename are appended to these.
URL example:
if `sharp_libvips_binary_host` is set to `https://hostname/path`
and the libvips version is `4.5.6` then the resultant URL will be
`https://hostname/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
Filename example:
if `sharp_libvips_local_prebuilds` is set to `/path`
and the libvips version is `4.5.6` then the resultant filename will be
`/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
See the Chinese mirror below for a further example.
If these binaries are modified, new integrity hashes can be provided
at install time via `npm_package_config_integrity_platform_arch`
environment variables, for example set
`npm_package_config_integrity_linux_x64` to `sha512-abc...`.
The integrity hash of a file can be generated via:
```sh
sha512sum libvips-x.y.z-platform-arch.tar.br | cut -f1 -d' ' | xxd -r -p | base64 -w 0
```
## Chinese mirror
A mirror site based in China, provided by Alibaba, contains binaries for both sharp and libvips.
To use this either set the following configuration:
```sh
npm config set sharp_binary_host "https://npmmirror.com/mirrors/sharp"
npm config set sharp_libvips_binary_host "https://npmmirror.com/mirrors/sharp-libvips"
npm install sharp
```
or set the following environment variables:
```sh
npm_config_sharp_binary_host="https://npmmirror.com/mirrors/sharp" \
npm_config_sharp_libvips_binary_host="https://npmmirror.com/mirrors/sharp-libvips" \
npm install sharp
```
## FreeBSD
The `vips` package must be installed before `npm install` is run.
```sh
pkg install -y pkgconf vips
```
```sh
cd /usr/ports/graphics/vips/ && make install clean
```
## Linux memory allocator
The default memory allocator on most glibc-based Linux systems
(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
processes that involve lots of small memory allocations.
For this reason, by default, sharp will limit the use of thread-based
[concurrency](api-utility#concurrency) when the glibc allocator is
detected at runtime.
To help avoid fragmentation and improve performance on these systems,
the use of an alternative memory allocator such as
[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
unaffected.
## AWS Lambda
The `node_modules` directory of the
[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
must include binaries for the Linux x64 platform.
When building your deployment package on machines other than Linux x64 (glibc),
run the following additional command after `npm install`:
```sh
npm install
rm -rf node_modules/sharp
SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux --libc=glibc sharp
```
To get the best performance select the largest memory available.
A 1536 MB function provides ~12x more CPU time than a 128 MB function.
When integrating with AWS API Gateway, ensure it is configured with the relevant
[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
## Bundlers
### webpack
Ensure sharp is excluded from bundling via the
[externals](https://webpack.js.org/configuration/externals/)
configuration.
```js
externals: {
'sharp': 'commonjs sharp'
}
```
### esbuild
Ensure sharp is excluded from bundling via the
[external](https://esbuild.github.io/api/#external)
configuration.
```js
buildSync({
entryPoints: ['app.js'],
bundle: true,
platform: 'node',
external: ['sharp'],
})
```
```sh
esbuild app.js --bundle --platform=node --external:sharp
```
For `serverless-esbuild`, ensure platform-specific binaries are installed
via the `serverless.yml` configuration.
```yaml
custom:
esbuild:
external:
- sharp
packagerOptions:
scripts:
- npm install --arch=x64 --platform=linux sharp
```
## TypeScript
TypeScript definitions are published as part of
the `sharp` package from v0.32.0.
Previously these were available via the `@types/sharp` package,
which is now deprecated.
When using Typescript, please ensure `devDependencies` includes
the `@types/node` package.
## Fonts
When creating text images or rendering SVG images that contain text elements,
`fontconfig` is used to find the relevant fonts.
On Windows and macOS systems, all system fonts are available for use.
On macOS systems using Homebrew, you may need to set the
`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
to ensure it is used for font discovery instead of Core Text.
On Linux systems, fonts that include the relevant
[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
when installed via package manager are available for use.
If `fontconfig` configuration is not found, the following error will occur:
```
Fontconfig error: Cannot load default config file
```
In serverless environments where there is no control over font packages,
use the `FONTCONFIG_PATH` environment variable to point to a custom location.
Embedded SVG fonts are unsupported.
## Worker threads
On some platforms, including glibc-based Linux,
the main thread must call `require('sharp')`
_before_ worker threads are created.
This is to ensure shared libraries remain loaded in memory
until after all threads are complete.
Without this, the following error may occur:
```
Module did not self-register
```
## Known conflicts
### Canvas and Windows
The prebuilt binaries provided by `canvas` for Windows
from v2.7.0 onwards depend on the Visual C++ Runtime (MSVCRT).
These conflict with the binaries provided by sharp,
which depend on the more modern Universal C Runtime (UCRT).
See [Automattic/node-canvas#2155](https://github.com/Automattic/node-canvas/issues/2155).
If both modules are used in the same Windows process, the following error will occur:
```
The specified procedure could not be found.
```

# Performance
A test to benchmark the performance of this module relative to alternatives.
Greater libvips performance can be expected with caching enabled (default)
and using 8+ core machines, especially those with larger L1/L2 CPU caches.
The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
## Contenders
* [jimp](https://www.npmjs.com/package/jimp) v0.22.7 - Image processing in pure JavaScript.
* [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "*has been unmaintained for a long time*".
* [gm](https://www.npmjs.com/package/gm) v1.25.0 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
* [@squoosh/lib](https://www.npmjs.com/package/@squoosh/lib) v0.4.0 - Image libraries transpiled to WebAssembly, includes GPLv3 code, but "*Project no longer maintained*".
* [@squoosh/cli](https://www.npmjs.com/package/@squoosh/cli) v0.7.3 - Command line wrapper around `@squoosh/lib`, avoids GPLv3 by spawning process, but "*Project no longer maintained*".
* sharp v0.32.0 / libvips v8.14.2 - Caching within libvips disabled to ensure a fair comparison.

title: Installation
---
Works with your choice of JavaScript package manager.
:::caution
Please ensure your package manager is configured to install optional dependencies
:::
If a package manager lockfile must support multiple platforms,
please see the [cross-platform](#cross-platform) section
to help decide which package manager is appropriate.
```sh
npm install sharp
```
```sh
pnpm add sharp
```
When using `pnpm`, you may need to add `sharp` to
[ignoredBuiltDependencies](https://pnpm.io/settings#ignoredbuiltdependencies)
to silence warnings.
```sh
yarn add sharp
```
```sh
bun add sharp
```
```sh
deno run --allow-ffi ...
```
## Prerequisites
* Node-API v9 compatible runtime e.g. Node.js ^18.17.0 or >=20.3.0.
## Prebuilt binaries
Ready-compiled sharp and libvips binaries are provided for use on the most common platforms:
* macOS x64 (>= 10.15)
* macOS ARM64
* Linux ARM (glibc >= 2.31)
* Linux ARM64 (glibc >= 2.26, musl >= 1.2.2)
* Linux ppc64 (glibc >= 2.31)
* Linux s390x (glibc >= 2.31)
* Linux x64 (glibc >= 2.26, musl >= 1.2.2, CPU with SSE4.2)
* Windows x64
* Windows x86
* Windows ARM64 (experimental, CPU with ARMv8.4 required for all features)
This provides support for the
JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
## Cross-platform
At install time, package managers will automatically select prebuilt binaries
for the current OS platform and CPU architecture, where available.
Some package managers support multiple platforms and architectures
within the same installation tree and/or using the same lockfile.
### npm v10+
:::caution
npm `package-lock.json` files shared by multiple platforms can cause installation problems due to [npm bug #4828](https://github.com/npm/cli/issues/4828)
:::
Provides limited support via `--os`, `--cpu` and `--libc` flags.
To support macOS with Intel x64 and ARM64 CPUs:
```sh
npm install --cpu=x64 --os=darwin sharp
npm install --cpu=arm64 --os=darwin sharp
```
When the cross-target is Linux, the C standard library must be specified.
To support glibc (e.g. Debian) and musl (e.g. Alpine) Linux with Intel x64 CPUs:
```sh
npm install --cpu=x64 --os=linux --libc=glibc sharp
npm install --cpu=x64 --os=linux --libc=musl sharp
```
### yarn v3+
Use the [supportedArchitectures](https://yarnpkg.com/configuration/yarnrc#supportedArchitectures) configuration.
### pnpm v8+
Use the [supportedArchitectures](https://pnpm.io/settings#supportedarchitectures) configuration.
## Custom libvips
To use a custom, globally-installed version of libvips instead of the provided binaries,
make sure it is at least the version listed under `config.libvips` in the `package.json` file
and that it can be located using `pkg-config --modversion vips-cpp`.
For help compiling libvips and its dependencies, please see
[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
The use of a globally-installed libvips is unsupported on Windows
and on macOS when running Node.js under Rosetta.
## Building from source
This module will be compiled from source at `npm install` time when:
* a globally-installed libvips is detected, or
* when the `npm install --build-from-source` flag is used.
The logic to detect a globally-installed libvips can be skipped by setting the
`SHARP_IGNORE_GLOBAL_LIBVIPS` (never try to use it) or
`SHARP_FORCE_GLOBAL_LIBVIPS` (always try to use it, even when missing or outdated)
environment variables.
Building from source requires:
* C++17 compiler
* [node-addon-api](https://www.npmjs.com/package/node-addon-api) version 7+
* [node-gyp](https://github.com/nodejs/node-gyp#installation) version 9+ and its dependencies
There is an install-time check for these dependencies.
If `node-addon-api` or `node-gyp` cannot be found, try adding them via:
```sh
npm install --save node-addon-api node-gyp
```
When using `pnpm`, you may need to add `sharp` to
[onlyBuiltDependencies](https://pnpm.io/settings#onlybuiltdependencies)
to ensure the installation script can be run.
For cross-compiling, the `--platform`, `--arch` and `--libc` npm flags
(or the `npm_config_platform`, `npm_config_arch` and `npm_config_libc` environment variables)
can be used to configure the target environment.
## WebAssembly
Experimental support is provided for runtime environments that provide
multi-threaded Wasm via Workers.
Use in web browsers is unsupported.
Native text rendering is unsupported.
[Tile-based output](/api-output#tile) is unsupported.
```sh
npm install --cpu=wasm32 sharp
```
## FreeBSD
The `vips` package must be installed before `npm install` is run.
```sh
pkg install -y pkgconf vips
```
```sh
cd /usr/ports/graphics/vips/ && make install clean
```
## Linux memory allocator
The default memory allocator on most glibc-based Linux systems
(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
processes that involve lots of small memory allocations.
For this reason, by default, sharp will limit the use of thread-based
[concurrency](/api-utility#concurrency) when the glibc allocator is
detected at runtime.
To help avoid fragmentation and improve performance on these systems,
the use of an alternative memory allocator such as
[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
unaffected.
## AWS Lambda
The `node_modules` directory of the
[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
must include binaries for either the linux-x64 or linux-arm64 platforms
depending on the chosen architecture.
When building your deployment package on a machine that differs from the target architecture,
see the [cross-platform](#cross-platform) section to help decide which package manager is appropriate
and how to configure it.
Some package managers use symbolic links
but AWS Lambda does not support these within deployment packages.
To get the best performance select the largest memory available.
A 1536 MB function provides ~12x more CPU time than a 128 MB function.
When integrating with AWS API Gateway, ensure it is configured with the relevant
[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
## Bundlers
### webpack
Ensure sharp is excluded from bundling via the
[externals](https://webpack.js.org/configuration/externals/)
configuration.
```js
externals: {
'sharp': 'commonjs sharp'
}
```
### esbuild
Ensure sharp is excluded from bundling via the
[external](https://esbuild.github.io/api/#external)
configuration.
```js
buildSync({
entryPoints: ['app.js'],
bundle: true,
platform: 'node',
external: ['sharp'],
})
```
```sh
esbuild app.js --bundle --platform=node --external:sharp
```
For `serverless-esbuild`, ensure platform-specific binaries are installed
via the `serverless.yml` configuration.
```yaml
custom:
esbuild:
external:
- sharp
packagerOptions:
scripts:
- npm install --os=linux --cpu=x64 sharp
```
### electron
#### electron-builder
Ensure `sharp` is unpacked from the ASAR archive file using the
[asarUnpack](https://www.electron.build/app-builder-lib.interface.platformspecificbuildoptions#asarunpack)
option.
```json
{
"build": {
"asar": true,
"asarUnpack": [
"**/node_modules/sharp/**/*",
"**/node_modules/@img/**/*"
]
}
}
```
#### electron-forge
Ensure `sharp` is unpacked from the ASAR archive file using the
[unpack](https://js.electronforge.io/interfaces/_electron_forge_maker_squirrel.InternalOptions.Options.html#asar)
option.
```json
{
"packagerConfig": {
"asar": {
"unpack": "**/node_modules/{sharp,@img}/**/*"
}
}
}
```
When using `electron-forge` with [Webpack](#webpack),
you may also need to add
[forge-externals-plugin](https://www.npmjs.com/package/@timfish/forge-externals-plugin).
### vite
Ensure `sharp` is excluded from bundling via the
[build.rollupOptions](https://vitejs.dev/config/build-options.html)
configuration.
```js
import { defineConfig } from 'vite';
export default defineConfig({
build: {
rollupOptions: {
external: [
"sharp"
]
}
}
});
```
## TypeScript
TypeScript definitions are published as part of
the `sharp` package from v0.32.0.
Previously these were available via the `@types/sharp` package,
which is now deprecated.
When using Typescript, please ensure `devDependencies` includes
the `@types/node` package.
## Fonts
When creating text images or rendering SVG images that contain text elements,
`fontconfig` is used to find the relevant fonts.
On Windows and macOS systems, all system fonts are available for use.
On macOS systems using Homebrew, you may need to set the
`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
to ensure it is used for font discovery instead of Core Text.
On Linux systems, fonts that include the relevant
[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
when installed via package manager are available for use.
If `fontconfig` configuration is not found, the following error will occur:
```
Fontconfig error: Cannot load default config file
```
In serverless environments where there is no control over font packages,
use the `FONTCONFIG_PATH` environment variable to point to a custom location.
Embedded SVG fonts are unsupported.
## Known conflicts
### Canvas and Windows
If both `canvas` and `sharp` modules are used in the same Windows process, the following error may occur:
```
The specified procedure could not be found.
```

title: Performance
---
## Parallelism and concurrency
Node.js uses a libuv-managed thread pool when processing asynchronous calls to native modules such as sharp.
The maximum number of images that sharp can process in parallel is controlled by libuv's
[`UV_THREADPOOL_SIZE`](https://nodejs.org/api/cli.html#uv_threadpool_sizesize)
environment variable, which defaults to 4.
When using more than 4 physical CPU cores, set this environment variable
before the Node.js process starts to increase the thread pool size.
```sh
export UV_THREADPOOL_SIZE="$(lscpu -p | egrep -v "^#" | sort -u -t, -k 2,4 | wc -l)"
```
libvips uses a glib-managed thread pool to avoid the overhead of spawning new threads.
The default number of threads used to concurrently process each image is the same as the number of CPU cores,
except when using glibc-based Linux without jemalloc, where the default is `1` to help reduce memory fragmentation.
Use [`sharp.concurrency()`](/api-utility/#concurrency) to manage the number of threads per image.
To reduce memory fragmentation when using the default Linux glibc memory allocator, set the
[`MALLOC_ARENA_MAX`](https://www.gnu.org/software/libc/manual/html_node/Memory-Allocation-Tunables.html)
environment variable before the Node.js process starts to reduce the number of memory pools.
```sh
export MALLOC_ARENA_MAX="2"
```
## Benchmark
A test to benchmark the performance of this module relative to alternatives.
Greater libvips performance can be expected with caching enabled (default)
and using 8+ core machines, especially those with larger L1/L2 CPU caches.
The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
### Contenders
- [jimp](https://www.npmjs.com/package/jimp) v1.6.0 - Image processing in pure JavaScript.
- [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "_has been unmaintained for a long time_".
- [gm](https://www.npmjs.com/package/gm) v1.25.1 - Fully featured wrapper around GraphicsMagick's `gm` command line utility, but "_has been sunset_".
- sharp v0.34.3 / libvips v8.17.0 - Caching within libvips disabled to ensure a fair comparison.
