flatten-brunch-map

flatten-brunch-map

Creates the object to return by a Brunch plugin, with the new sourcemap merged with the preceding sourcemap if necessary.

Install

npm install flatten-brunch-map --save

Usage

const flattenMap = require('flatten-brunch-map')
...
const pluginResult = flattenMap(fileParam, compiledCode, sourceMap)

Example

const flattenMap = require('flatten-brunch-map')
const myCompiler = require('myCompiler')

class MyPlugin {

  constructor (config) {
    this.options = config.plugins.myPlugin || {}
    // Tell to myCompiler if user wants sourcemap
    this.options.sourceMaps = !!config.sourceMaps
  }

  compile (file) {
    return new Promise((resolve, reject) => {
      try {
        // Do the plugin logic and then call flattenMap with the
        // received param and the generated code and sourcemap.
        const output = myCompiler(file.data, this.options)
        const result = this.options.sourceMaps
                     ? flattenMap(file, output.code, output.map) : output.code

        resolve(result)
      } catch (error) {
        reject(error)
      }
    })
  }
}

MyPlugin.prototype.brunchPlugin = true
MyPlugin.prototype.extension = 'js'
MyPlugin.prototype.type = 'javascript'

module.exports = MyPlugin

What's New

From v2.8.2, the plugin returns a normalized string or plain object with sources defaulting to the received file path.
