Quick Tip: Make Composer Auto-Update Itself

Composer is a great package manager for PHP. It allows us to install, update and upgrade third-party libraries. For those who don’t know about composer, here is a good beginners guide on the topic.

Now we know once in a while, composer needs to update its build so it can have the latest security fixes and patches. This can sometimes get annoying as most people (points to self) forget to update their build. If you have used composer for a period longer than 60days, you might have seen this message.

Warning: This development build of composer is over 60 days old. It is recommended to update it by running "C:/ProgramData/ComposerSetup/bin/composer.phar self- update" to get the latest version.

This quick tip article aims to tackle that problem by letting composer auto-update itself. For composer to auto-update itself, all we have to is set up a command that runs on a certain interval. I set mine to every Saturday. I assume you know composer and have it installed. For more info, check outthis article.

Setup Composer auto-update on Linux

To make composer auto-update on any Linux-based computer, all we need to do is setup a cron task. Don’t know about cron, check out this DigitalOcean article . Open your cronfile and add the command.

5 8 * * Sat /path/to/composer/executable self-update

For example, since my composer executable is in usr/bin , mine cron task will look like this.

5 8 * * Sat /usr/bin/composer self-update

This lets composer update itself every Saturday morning at five minutes past eight.

Note:If you don’t know where composer installed on your computer, you can open a terminal and run the following command to get composer’s install path.

which composer

Since I use MinGW on windows to make Linux commands available for me, the result of running the above command looks like this.
