# Config
|
|
|
|
This chapter will describe the `config` section of the `composer.json`
|
|
[schema](04-schema.md).
|
|
|
|
## process-timeout
|
|
|
|
Defaults to `300`. The duration processes like git clones can run before
|
|
Composer assumes they died out. You may need to make this higher if you have a
|
|
slow connection or huge vendors.
|
|
|
|
## 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 `auto` and can be any of `source`, `dist` or `auto`. This option
|
|
allows you to set the install method Composer will prefer to use.
|
|
|
|
## 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 `["git", "https", "ssh"]`. A list of protocols to use when cloning
|
|
from github.com, in priority order. You can reconfigure it to for example
|
|
prioritize the https protocol if you are behind a proxy or have somehow bad
|
|
performances with the git protocol.
|
|
|
|
## 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. [Read
|
|
more](articles/troubleshooting.md#api-rate-limit-and-oauth-tokens) on how to get
|
|
an OAuth token for GitHub.
|
|
|
|
## 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.
|
|
|
|
> **Note:** Authentication-related config options like `http-basic` and
|
|
> `github-oauth` can also be specified inside a `auth.json` file that goes
|
|
> besides your `composer.json`. That way you can gitignore it and every
|
|
> developer can place their own credentials in there.
|
|
|
|
## 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":
|
|
"5.4", "ext-something": "4.0"}`.
|
|
|
|
## vendor-dir
|
|
|
|
Defaults to `vendor`. You can install dependencies into a different directory if
|
|
you want to. `$HOME` and `~` will be replaced by your home directory's path in
|
|
vendor-dir and all `*-dir` options below.
|
|
|
|
## bin-dir
|
|
|
|
Defaults to `vendor/bin`. If a project includes binaries, they will be symlinked
|
|
into this directory.
|
|
|
|
## cache-dir
|
|
|
|
Defaults to `$COMPOSER_HOME/cache` on unix systems and
|
|
`C:\Users\<user>\AppData\Local\Composer` on Windows. Stores all the caches used
|
|
by Composer. See also [COMPOSER_HOME](03-cli.md#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`, `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.
|
|
|
|
## 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. 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.
|
|
|
|
## 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`. String to be used as a suffix for the generated Composer
|
|
autoloader. When null a random one will be generated.
|
|
|
|
## optimize-autoloader
|
|
|
|
Defaults to `false`. If `true`, always optimize when dumping the autoloader.
|
|
|
|
## classmap-authoritative
|
|
|
|
Defaults to `false`. If `true`, the Composer autoloader will only load classes
|
|
from the classmap. Implies `optimize-autoloader`.
|
|
|
|
## 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.
|
|
|
|
## gitlab-domains
|
|
|
|
Defaults to `["gitlab.com"]`. A list of domains of GitLab servers.
|
|
This is used if you use the `gitlab` repository type.
|
|
|
|
## 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 behaviour.
|
|
|
|
## 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`. Composer allows you to add a default archive format when the
|
|
workflow needs to create a dedicated archiving format.
|
|
|
|
## archive-dir
|
|
|
|
Defaults to `.`. Composer allows you to add a default archive directory when the
|
|
workflow needs to create a dedicated archiving format. Or for easier development
|
|
between modules.
|
|
|
|
Example:
|
|
|
|
```json
|
|
{
|
|
"config": {
|
|
"archive-dir": "/home/user/.composer/repo"
|
|
}
|
|
}
|
|
```
