rollup-plugin-codefilter
This is a plugin for rollup/vite that filter code by dotenv variables.
install
npm install rollup-plugin-codefilter --save-dev
quick start
create a rollup.config.js
configuration file and import the plugin:
import codeFilter from 'rollup-plugin-codefilter'
module.exports = {
input: 'index.js',
output: {
file: 'bundle.js',
format: 'iife',
name: 'test'
},
plugins: [
codeFilter()
]
}
create a .env
configuration file and define some true or false variables.
keep = true
discard = false
create index.js
:
function log () {
// ifdef keep
console.log('hello world!')
// endif
// ifdef discard
console.log('it will be discarded.')
// endif
}
export default log
Finally, run rollup -c rollup.config.js
.
The file will be generated in folder dist
:
var test = (function () {
'use strict';
function log () {
console.log('hello world!');
}
return log;
}());
