A fuse-box plugin for unassert: Encourages programming with assertions by providing tools to compile them away.
npm install fusebox-unassert-pluginUnassertPlugin is a fuse-box plugin to remove assertions on production builds.
See unassert project for more documentation.
Install fusebox-unassert-plugin via npm:
``console`
$ npm install --save-dev fusebox-unassert-plugin
Import plugin
`js`
const { UnassertPlugin } = require("fusebox-unassert-plugin");
Inject into a chain
`js`
fuse.bundle("app").plugin(UnassertPlugin());
Or add it to the main config plugins list to make it available across bundles.
`js`
FuseBox.init({
plugins: [UnassertPlugin()],
});
The plugin will parse source files (.js, .jsx, .ts, .tsx) into syntax trees by using esprima, and then re-generate JavaScript using escodegen. It is primarily intended for Quantum and uglified builds since the output will not have identical formatting to the input.
`js`
FuseBox.init({
plugins: [
...
this.isProduction && UnassertPlugin(),
this.isProduction && QuantumPlugin({ uglify:true })
],
});
You can pass unassert options, if not passed, default options (Same as unassert.defaultOptions()) will be used.
