Config#
This chapter will describe the config
section of the composer.json
schema.
process-timeout#
The timeout in seconds for process executions, defaults to 300 (5mins).
The duration processes like git clone
s can run before
Composer assumes they died out. You may need to make this higher if you have a
slow connection or huge vendors.
Example:
{
"config": {
"process-timeout": 900
}
}
Disabling timeouts for an individual script command#
To disable the process timeout on a custom command under scripts
, a static
helper is available:
{
"scripts": {
"test": [
"Composer\\Config::disableProcessTimeout",
"phpunit"
]
}
}
allow-plugins#
Defaults to {}
which does not allow any plugins to be loaded.
As of Composer 2.2.0, the allow-plugins
option adds a layer of security
allowing you to restrict which Composer plugins are able to execute code during
a Composer run.
When a new plugin is first activated, which is not yet listed in the config option, Composer will print a warning. If you run Composer interactively it will prompt you to decide if you want to execute the plugin or not.
Use this setting to allow only packages you trust to execute code. Set it to an object with package name patterns as keys. The values are true to allow and false to disallow while suppressing further warnings and prompts.
{
"config": {
"allow-plugins": {
"third-party/required-plugin": true,
"my-organization/*": true,
"unnecessary/plugin": false
}
}
}
You can also set the config option itself to false
to disallow all plugins, or true
to allow all plugins to run (NOT recommended). For example:
{
"config": {
"allow-plugins": false
}
}
use-include-path#
Defaults to false
. If true
, the Composer autoloader will also look for classes
in the PHP include path.
preferred-install#
Defaults to dist
and can be any of source
, dist
or auto
. This option
allows you to set the install method Composer will prefer to use. Can
optionally be an object with package name patterns for keys for more granular install preferences.
{
"config": {
"preferred-install": {
"my-organization/stable-package": "dist",
"my-organization/*": "source",
"partner-organization/*": "auto",
"*": "dist"
}
}
}
source
means Composer will install packages from theirsource
if there is one. This is typically a git clone or equivalent checkout of the version control system the package uses. This is useful if you want to make a bugfix to a project and get a local git clone of the dependency directly.auto
is the legacy behavior where Composer usessource
automatically for dev versions, anddist
otherwise.dist
(the default as of Composer 2.1) means Composer installs fromdist
, where possible. This is typically a zip file download, which is faster than cloning the entire repository.
Note: Order matters. More specific patterns should be earlier than more relaxed patterns. When mixing the string notation with the hash configuration in global and package configurations the string notation is translated to a
*
package pattern.
audit#
Security audit configuration options
ignore#
A list of advisory ids, remote ids or CVE ids that are reported but let the audit command pass.
{
"config": {
"audit": {
"ignore": {
"CVE-1234": "The affected component is not in use.",
"GHSA-xx": "The security fix was applied as a patch.",
"PKSA-yy": "Due to mitigations in place the update can be delayed."
}
}
}
}
or
{
"config": {
"audit": {
"ignore": ["CVE-1234", "GHSA-xx", "PKSA-yy"]
}
}
}
abandoned#
Defaults to report
in Composer 2.6, and defaults to fail
from Composer 2.7 on. Defines whether the audit command reports abandoned packages or not, this has three possible values:
ignore
means the audit command does not consider abandoned packages at all.report
means abandoned packages are reported as an error but do not cause the command to exit with a non-zero code.fail
means abandoned packages will cause audits to fail with a non-zero code.
{
"config": {
"audit": {
"abandoned": "report"
}
}
}
Since Composer 2.7, the option can be overridden via the COMPOSER_AUDIT_ABANDONED
environment variable.
Since Composer 2.8, the option can be overridden via the
--abandoned
command line option, which overrides both the
config value and the environment variable.
use-parent-dir#
When running Composer in a directory where there is no composer.json, if there is one present in a directory above Composer will by default ask you whether you want to use that directory's composer.json instead.
If you always want to answer yes to this prompt, you can set this config value
to true
. To never be prompted, set it to false
. The default is "prompt"
.
Note: This config must be set in your global user-wide config for it to work. Use for example
php composer.phar config --global use-parent-dir true
to set it.
store-auths#
What to do after prompting for authentication, one of: true
(always store),
false
(do not store) and "prompt"
(ask every time), defaults to "prompt"
.
github-protocols#
Defaults to ["https", "ssh", "git"]
. A list of protocols to use when cloning
from github.com, in priority order. By default git
is present but only if secure-http
is disabled, as the git protocol is not encrypted. If you want your origin remote
push URLs to be using https and not ssh (git@github.com:...
), then set the protocol
list to be only ["https"]
and Composer will stop overwriting the push URL to an ssh
URL.
github-oauth#
A list of domain names and oauth keys. For example using {"github.com": "oauthtoken"}
as the value of this option will use oauthtoken
to access
private repositories on github and to circumvent the low IP-based rate limiting
of their API. Composer may prompt for credentials when needed, but these can also be
manually set. Read more on how to get an OAuth token for GitHub and cli syntax
here.
gitlab-domains#
Defaults to ["gitlab.com"]
. A list of domains of GitLab servers.
This is used if you use the gitlab
repository type.
gitlab-oauth#
A list of domain names and oauth keys. For example using {"gitlab.com": "oauthtoken"}
as the value of this option will use oauthtoken
to access
private repositories on gitlab. Please note: If the package is not hosted at
gitlab.com the domain names must be also specified with the
gitlab-domains
option.
Further info can also be found here
gitlab-token#
A list of domain names and private tokens. Private token can be either simple
string, or array with username and token. For example using {"gitlab.com": "privatetoken"}
as the value of this option will use privatetoken
to access
private repositories on gitlab. Using {"gitlab.com": {"username": "gitlabuser", "token": "privatetoken"}}
will use both username and token for gitlab deploy
token functionality (https://docs.gitlab.com/ee/user/project/deploy_tokens/)
Please note: If the package is not hosted at
gitlab.com the domain names must be also specified with the
gitlab-domains
option. The token must have
api
or read_api
scope.
Further info can also be found here
gitlab-protocol#
A protocol to force use of when creating a repository URL for the source
value of the package metadata. One of git
or http
. (https
is treated
as a synonym for http
.) Helpful when working with projects referencing
private repositories which will later be cloned in GitLab CI jobs with a
GitLab CI_JOB_TOKEN
using HTTP basic auth. By default, Composer will generate a git-over-SSH
URL for private repositories and HTTP(S) only for public.
disable-tls#
Defaults to false
. If set to true all HTTPS URLs will be tried with HTTP
instead and no network level encryption is performed. Enabling this is a
security risk and is NOT recommended. The better way is to enable the
php_openssl extension in php.ini. Enabling this will implicitly disable the
secure-http
option.
secure-http#
Defaults to true
. If set to true only HTTPS URLs are allowed to be
downloaded via Composer. If you really absolutely need HTTP access to something
then you can disable it, but using Let's Encrypt to
get a free SSL certificate is generally a better alternative.
bitbucket-oauth#
A list of domain names and consumers. For example using {"bitbucket.org": {"consumer-key": "myKey", "consumer-secret": "mySecret"}}
.
Read more here.
cafile#
Location of Certificate Authority file on local filesystem. In PHP 5.6+ you should rather set this via openssl.cafile in php.ini, although PHP 5.6+ should be able to detect your system CA file automatically.
capath#
If cafile is not specified or if the certificate is not found there, the directory pointed to by capath is searched for a suitable certificate. capath must be a correctly hashed certificate directory.
http-basic#
A list of domain names and username/passwords to authenticate against them. For
example using {"example.org": {"username": "alice", "password": "foo"}}
as the
value of this option will let Composer authenticate against example.org.
More info can be found here.
bearer#
A list of domain names and tokens to authenticate against them. For example using
{"example.org": "foo"}
as the value of this option will let Composer authenticate
against example.org using an Authorization: Bearer foo
header.
platform#
Lets you fake platform packages (PHP and extensions) so that you can emulate a
production env or define your target platform in the config. Example: {"php": "7.0.3", "ext-something": "4.0.3"}
.
This will make sure that no package requiring more than PHP 7.0.3 can be installed
regardless of the actual PHP version you run locally. However it also means
the dependencies are not checked correctly anymore, if you run PHP 5.6 it will
install fine as it assumes 7.0.3, but then it will fail at runtime. This also means if
{"php":"7.4"}
is specified; no packages will be used that define 7.4.1
as minimum.
Therefore if you use this it is recommended, and safer, to also run the
check-platform-reqs
command as part of your
deployment strategy.
If a dependency requires some extension that you do not have installed locally
you may ignore it instead by passing --ignore-platform-req=ext-foo
to update
,
install
or require
. In the long run though you should install required
extensions as if you ignore one now and a new package you add a month later also
requires it, you may introduce issues in production unknowingly.
If you have an extension installed locally but not on production, you may want
to artificially hide it from Composer using {"ext-foo": false}
.
vendor-dir#
Defaults to vendor
. You can install dependencies into a different directory if
you want to. $HOME
and ~
will be replaced by your home directory's path in
vendor-dir and all *-dir
options below.
bin-dir#
Defaults to vendor/bin
. If a project includes binaries, they will be symlinked
into this directory.
data-dir#
Defaults to C:\Users\<user>\AppData\Roaming\Composer
on Windows,
$XDG_DATA_HOME/composer
on unix systems that follow the XDG Base Directory
Specifications, and $COMPOSER_HOME
on other unix systems. Right now it is only
used for storing past composer.phar files to be able to roll back to older
versions. See also COMPOSER_HOME.
cache-dir#
Defaults to C:\Users\<user>\AppData\Local\Composer
on Windows,
/Users/<user>/Library/Caches/composer
on macOS, $XDG_CACHE_HOME/composer
on unix systems that follow the XDG Base Directory Specifications, and
$COMPOSER_HOME/cache
on other unix systems. Stores all the caches used by
Composer. See also COMPOSER_HOME.
cache-files-dir#
Defaults to $cache-dir/files
. Stores the zip archives of packages.
cache-repo-dir#
Defaults to $cache-dir/repo
. Stores repository metadata for the composer
type and the VCS repos of type svn
, fossil
, github
and bitbucket
.
cache-vcs-dir#
Defaults to $cache-dir/vcs
. Stores VCS clones for loading VCS repository
metadata for the git
/hg
types and to speed up installs.
cache-files-ttl#
Defaults to 15552000
(6 months). Composer caches all dist (zip, tar, ...)
packages that it downloads. Those are purged after six months of being unused by
default. This option allows you to tweak this duration (in seconds) or disable
it completely by setting it to 0.
cache-files-maxsize#
Defaults to 300MiB
. Composer caches all dist (zip, tar, ...) packages that it
downloads. When the garbage collection is periodically ran, this is the maximum
size the cache will be able to use. Older (less used) files will be removed
first until the cache fits.
cache-read-only#
Defaults to false
. Whether to use the Composer cache in read-only mode.
bin-compat#
Defaults to auto
. Determines the compatibility of the binaries to be installed.
If it is auto
then Composer only installs .bat proxy files when on Windows or WSL. If
set to full
then both .bat files for Windows and scripts for Unix-based
operating systems will be installed for each binary. This is mainly useful if you
run Composer inside a linux VM but still want the .bat
proxies available for use
in the Windows host OS. If set to proxy
Composer will only create bash/Unix-style
proxy files and no .bat files even on Windows/WSL.
prepend-autoloader#
Defaults to true
. If false
, the Composer autoloader will not be prepended to
existing autoloaders. This is sometimes required to fix interoperability issues
with other autoloaders.
autoloader-suffix#
Defaults to null
. When set to a non-empty string, this value will be used as a
suffix for the generated Composer autoloader. If set to null
, the
content-hash
value from the composer.lock
file will be used if available;
otherwise, a random suffix will be generated.
optimize-autoloader#
Defaults to false
. If true
, always optimize when dumping the autoloader.
sort-packages#
Defaults to false
. If true
, the require
command keeps packages sorted
by name in composer.json
when adding a new package.
classmap-authoritative#
Defaults to false
. If true
, the Composer autoloader will only load classes
from the classmap. Implies optimize-autoloader
.
apcu-autoloader#
Defaults to false
. If true
, the Composer autoloader will check for APCu and
use it to cache found/not-found classes when the extension is enabled.
github-domains#
Defaults to ["github.com"]
. A list of domains to use in github mode. This is
used for GitHub Enterprise setups.
github-expose-hostname#
Defaults to true
. If false
, the OAuth tokens created to access the
github API will have a date instead of the machine hostname.
use-github-api#
Defaults to true
. Similar to the no-api
key on a specific repository,
setting use-github-api
to false
will define the global behavior for all
GitHub repositories to clone the repository as it would with any other git
repository instead of using the GitHub API. But unlike using the git
driver directly, Composer will still attempt to use GitHub's zip files.
notify-on-install#
Defaults to true
. Composer allows repositories to define a notification URL,
so that they get notified whenever a package from that repository is installed.
This option allows you to disable that behavior.
discard-changes#
Defaults to false
and can be any of true
, false
or "stash"
. This option
allows you to set the default style of handling dirty updates when in
non-interactive mode. true
will always discard changes in vendors, while
"stash"
will try to stash and reapply. Use this for CI servers or deploy
scripts if you tend to have modified vendors.
archive-format#
Defaults to tar
. Overrides the default format used by the archive command.
archive-dir#
Defaults to .
. Default destination for archives created by the archive
command.
Example:
{
"config": {
"archive-dir": "/home/user/.composer/repo"
}
}
htaccess-protect#
Defaults to true
. If set to false
, Composer will not create .htaccess
files
in the Composer home, cache, and data directories.
lock#
Defaults to true
. If set to false
, Composer will not create a composer.lock
file and will ignore it if one is present.
platform-check#
Defaults to php-only
which only checks the PHP version. Set to true
to also
check the presence of extension. If set to false
, Composer will not create and
require a platform_check.php
file as part of the autoloader bootstrap.
secure-svn-domains#
Defaults to []
. Lists domains which should be trusted/marked as using a secure
Subversion/SVN transport. By default svn:// protocol is seen as insecure and will
throw, but you can set this config option to ["example.org"]
to allow using svn
URLs on that hostname. This is a better/safer alternative to disabling secure-http
altogether.
bump-after-update#
Defaults to false
and can be any of true
, false
, "dev"
or "no-dev"
. If
set to true, Composer will run the bump
command after running the update
command.
If set to "dev"
or "no-dev"
then only the corresponding dependencies will be bumped.
allow-missing-requirements#
Defaults to false
. Ignores error during install
if there are any missing
requirements - the lock file is not up to date with the latest changes in
composer.json
.
