CodeIgniter Composer “package.json” locations shluld be in application or root folder?

问题

I working with code igniter v3.x and I would like to add some composer packages.

looking at application/config/config.php file, it says that will load packages inside application folder

| package auto-loader script in application/vendor/autoload.php.

However in the codeigniter package it already has a package.json that installs packages on root folder.

I suspect that the package.json on the root must hold only information about CodeIgniter it self. But I'm not sure.

So I have three options:

1. Create a new package.json inside the application folder and install packages inside application.

2. Modify the package.json on the root folder by adding new package and change autoload.php location

What is expected from a CodeIgniter Application?

Well, if you take a look at the Codeigniter Documentation you can see there is a Configuration setting called composer_autoload. This information can be found here.

If you set this true, Codeigniter tries to load Composer's autoload.php in the APPLICATION.'vendor' folder. If you take a closer look at the Codeigniter.php file, you'll see that you can define a directory for this setting too.

So in your case you don't have to change the package.json in the root folder because you need one in the application folder, in case you set composer_autoload to true, which i would recommend.

By the way if you try to install a package via composer in your application directory, composer asks you if you want to use the one it found on the root folder - just decline that and press n.

As you can see in the picture below (i just tried to install the mpdf package).
