composer.json在composer update上执行

Question

I have one questions related to composer: Please look at following directory structure in laravel.

laravel
|-- app
|-- bootstrap
|-- config
|-- composer.json
|-- composer.lock
`-- vendor
    |-- composer
    |-- danielstjules
    |   |-- composer.json
    |   `-- and other files
    |-- dnoegel
    |   |-- composer.json
    |   `-- and other files
    |-- doctrine
    |   |-- composer.json
    |   `-- and other files
    `-- doctrine
        |-- composer.json
        `-- and other files

and i am using composer to manage dependency. On my directory structutre, there are many files of composer.json, mainly in vendor folder,in all sub-folder of vendor directory has a composer.json file.

then my question is : if i exceute composer update command from my app folder like :

vishal@vishal-desktop /var/www/laravel $ composer update

1) which composer.json will be updated only of app diectory? or

2) all composer.json of all subfolder in /var/www/laravel folder?

Answer 1

composer update in the root folder of laravel is only looking at the composer.json in your docroot as well so it knows what dependencies, etc it should look for updates for. The other composer files are for the modules they belong to.

You shouldn't be modifying the vendor folder, either.
