typescript-plugin-unassert


Motivation

Assertion Functions is available from TypeScript 3.7, but assertion functions are called and processed always, even in production codes.

This plugin eliminates all of assert and assertIsDefined calls, that are introduced at the official page.

Getting Started

``console
npm install --save-dev typescript-plugin-unassert ts-loader


or


yarn add --dev typescript-plugin-unassert ts-loader
`

Write following lines in your webpack.config.json.

`js
const unassertTransformer = require('typescript-plugin-unassert')

// snip

module.exports = {
// snip
module: {
rules: [
{
test: /\.tsx?$/,
loader: 'ts-loader',
options: {
getCustomTransformers: () => ({
before: [unassertTransformer],
}),
},
exclude: /node_modules/,
},
],
},
// snip
}
`

Make sure to specify something except for "CommonJS" for the "module" property in tsconfig.json if you need tree shaking.

See example` dir which is minimum usage.
