Important

This project will look for two environment variables; ROC_CONFIG and ROC_CONFIG_OBJECT.
If ROC_CONFIG_OBJECT is found those will be used instead of what has been appended during runtime elsewhere.

If there is a conflict where both an environment variable is set and something is appended manually, there will a a clear warning given to the user.

Once imported to your project the configuration and all its internal states will persist throughout the process lifetime.

Documentation

To generate documentation please run npm run docs.

Configuration source priority

Configurations provided by environment ROC_CONFIG_OBJECT have highest priority amongst appends. This overwrites all other appended properties without merge.

If a configuration file path is provided by environment ROC_CONFIG it will load this instead of a configuration file within the project, without merging the two. Note that it is subject to programmatic appends, it just loads from a different file.

getFinalConfig() will merge any appended programmatic configuration (or environment object) into configurations loaded from file and then finally merge this into it's own optional configuration parameter.

Application Configuration Format

For roc-config to understand a roc.config.js provided by the CLI or ROC_CONFIG it needs to export an object with a config key. This example should give a basic idea. Configurations will vary amongst Roc extensions, but they must always expose the config key at the time that it is called.

module.exports = {
    config: {
        port: 8080,
        serve: 'files',
        build: {
            entry: {
                client: 'client.js',
                server: 'server.js'
            }
        },
        dev: {
            open: true
        }
    }
};

This example works with roc-web

API Examples

Use configuration:

import { getFinalConfig } from 'roc-config';
 
const config = getFinalConfig();
 

Extend configuration with custom configuration and use it:

import { getFinalConfig } from 'roc-config';
 
const customConfig = {
    property: 'value'
};
 
const config = getFinalConfig(customConfig);

Perform multiple modifications and use:

import { getFinalConfig, appendConfig } from 'roc-config';
 
// deep merges parameter to current appended configuration state
appendConfig({
    value: 'value'
});
 
appendConfig({
    value2: 'value2'
});
 
// config will hold { "value": "value", "value2": "value2" }
const config = getFinalConfig();
