babel-plugin-config-export

Export config options from source files without actually running them.

Install

$ npm install --save babel-plugin-config-export

Usage

Get the value of a specially named export without running a file. The export must not contain any computed values, and must be computable in place:

// in a source file
export const myConfig = {
  serial: true,
  topLevel: true
};

// when processing sources
import makePlugin from 'babel-plugin-config-export';

const myPlugin = makePlugin('myConfig');

const result = babel.transform(sourceString, {
  plugins: [myPlugin]
});

myPlugin.getConfig(result);
// {serial: true, topLevel: true}

API

makePlugin(configName)

Creates a babel plugin that will extract the configName export, and store it in the parse result metadata. Returns a babel plugin.

configName

Type: string

The named export to compute.

makePlugin.getConfig(parseResult, configName)

generatedPlugin.getConfig(parseResult)

Extracts the computed value from the parse result metadata. The generated plugin has a curried getConfig that does not require passing configName.
