babel-plugin-hash-strings

Replace all instances of "@@strings like this" with hashes.

This might be useful for decreasing the size of your JavaScript bundles. But note that gzip might actually be better for your code because hashes do not compress well.

Install

npm install --save-dev babel-plugin-hash-strings

Usage

It's recommended that you only use this plugin in a production build.

// babel.config.js
let presets = [ ... ]
let plugins = [ ... ]

if (process.env.NODE_ENV === "production") {
  plugins.push("babel-plugin-hash-strings")
}

module.exports = { presets, plugins }

Example

Input:

let value = "@@hash me"

Output:

let value = "5953c"

options.chars

This plugin defaults to really short hashes because you probably won't have that many strings that uniqueness matters all that much. But just in case you do have a duplicate, the plugin has a built-in check for them and you can increase the length of your strings using options.chars

// babel.config.js
let presets = [ ... ]
let plugins = [ ... ]

if (process.env.NODE_ENV === "production") {
  plugins.push(["babel-plugin-hash-strings", {
    chars: 8 // (default: 5)
  }])
}

module.exports = { presets, plugins }
