rollup-plugin-concat
A Rollup plugin which concatenates files together for further use by the rollup bundling process.
Install
Using npm:
npm install rollup-plugin-concat --save-dev
Usage
Create a rollup.config.js configuration file and import the plugin:
import concat from 'rollup-plugin-concat';
export default {
input: 'src/index.js',
output: {
file: 'bundle.js',
format: 'esm'
},
plugins: [
concat({
groupedFiles: [
{
files: ['./fileA.js', './fileB.js'],
outputFile: './ab.js',
},
{
files: ['./fileC.js', './fileD.js'],
outputFile: './cd.js',
},
],
}),
],
//other plugins go here
}
Then call rollup either via the CLI or the API.
The configuration above will concatenate the files and output them to a specified output file.
As the plugin runs on the buildStart hook, the outputted file will then be available by other plugins to be imported.
Typically, rollup-plugin-concat should be placed before other plugins so that they may import the concatenated files if needed.
Options
groupedFiles
Type: Array[{ files : String, outputFile : String}]
Describes a collection of file concatenation groups. Each group should consist of an object that includes a "files" property, indicating the files to be concatenated, and an "outputFile" property indicating the resulting file after concatenation.
