What is @expo/config?

@expo/config is a package that provides utilities for reading, writing, and modifying Expo configuration files. It is particularly useful for managing app.json and app.config.js files in Expo projects.

What are @expo/config's main functionalities?

Reading Configuration

This feature allows you to read the configuration of an Expo project. The `getConfig` function reads the app.json or app.config.js file and returns the configuration object.

const { getConfig } = require('@expo/config');
const config = getConfig('/path/to/project');
console.log(config);

Modifying Configuration

This feature allows you to modify the configuration of an Expo project. The `modifyConfigAsync` function takes the path to the project and an object with the modifications you want to make.

const { modifyConfigAsync } = require('@expo/config');
(async () => {
  const result = await modifyConfigAsync('/path/to/project', {
    updates: {
      enabled: true
    }
  });
  console.log(result);
})();

Writing Configuration

This feature allows you to write a new configuration to the app.json file. The `writeConfigJsonAsync` function takes the path to the project and the new configuration object.

const { writeConfigJsonAsync } = require('@expo/config');
(async () => {
  const result = await writeConfigJsonAsync('/path/to/project', {
    name: 'NewAppName',
    slug: 'new-app-slug'
  });
  console.log(result);
})();

    config

    The 'config' package is a configuration manager for Node.js applications. It allows you to define a set of default parameters and override them with environment-specific values. Unlike @expo/config, it is not specific to Expo projects and can be used in any Node.js application.

    rc

    The 'rc' package is a non-opinionated configuration loader for Node.js applications. It loads configuration options from a variety of sources, including command-line arguments, environment variables, and configuration files. It is more flexible but less specialized than @expo/config.
