Question 1

How do I install a private WordPress plugin like ACF Pro with private-composer-installer?

Accepted Answer

Add a custom package repository to composer.json with a dist URL containing {%PLUGIN_ACF_KEY} and {%VERSION} placeholders, set the key in a .env file, then run composer require with the package name and wildcard version, as shown in the WordPress plugin example.

Question 2

private-composer-installer vs Basic HTTP Auth in Composer: which is better?

Accepted Answer

Use private-composer-installer when you can't control the package source or need to avoid storing credentials in files. Basic HTTP Auth is simpler if you have server access and can set credentials globally, but it stores them in auth.json.

Question 3

What should I do if I get a MissingEnvException?

Accepted Answer

Ensure the required environment variable is set in your system or .env file. The plugin throws this error to prevent incomplete installations, so check variable names and file paths as per the configuration options.

Question 4

Can I use private-composer-installer without a .env file?

Accepted Answer

Yes, you can set environment variables directly in your shell or deployment environment. The plugin checks the environment first before falling back to .env file loading, but .env integration is a key convenience feature.

Question 5

How to manage multiple private packages with different keys?

Accepted Answer

Define each package in the repositories section of composer.json with unique {%VARIABLE} placeholders, and set corresponding environment variables in your .env file or system environment, following the examples for arbitrary packages.

Question 6

Is private-composer-installer compatible with Dockerized setups?

Accepted Answer

Yes, it works with Docker as long as environment variables are passed to the container or a .env file is mounted. The plugin's reliance on dotenv makes it adaptable to containerized environments with proper configuration.
