npm install --save-dev obfuscator-loader`What's new in 1.1.1
option is now available. Thank you Timofey Kachalov.
Why not a plugin?
Obfuscating code can results in quite large files. It's a good idea to obfuscate only your code leaving third party libraries unobfuscated.
This is simple to achieve using a plugin if you plan to split your code and third party code in different bundles. Take a look at this plugin.
Sometimes you need to output a single js bundle but you still need to obfuscate the source code of some particular module. In these cases a loader can do the trick.
For example I happened to had to bundle a big third party library (not a module of any sort, I had to use script-loader) in one of my project and I was requested to obfuscate my code.
Usage
Define a rule in your webpack config and use the obfuscator-loader as the last of your loaders for your modules. You can add the enforce: 'post' flag to ensure the loader will be called after normal loaders:`javascript
module.exports = {
module: {
rules: [
{
test: /\.js$/,
include: [ path.resolve(__dirname, "justMySources") ],
enforce: 'post',
use: { loader: 'obfuscator-loader', options: {/ options here /} }
},
]
}
};
`Options
This loader accepts the same options object of javascript-obfuscatorLicense
