rollup-plugin-replace
Replace strings in files while bundling them.
Installation
npm install --save-dev rollup-plugin-replace
Usage
Generally, you need to ensure that rollup-plugin-replace goes before other things (like rollup-plugin-commonjs) in your plugins array, so that those plugins can apply any optimisations such as dead code removal.

Word boundaries
By default, values will only match if they are surrounded by word boundaries — i.e. with options like this...

console.log('replaced');console.log('unchanged');
If that's not what you want, specify empty strings as delimiters:
