    Terser is JavaScript compressor that can minified specific method names.

    A minifier makes your code more compact so that it loads faster. Popular minifiers: Terser, swc.
  • Overview of the next-gen frontend dev tools
    4 projects | | 8 Nov 2022
    There are many minifiers such as terser and uglify. But, because minifying also require to parse the JS, it is actually possible to use esbuild and SWC to minify the code. Here's a benchmark of the main minifiers.
  • Rollup Library Starter
    9 projects | | 5 Oct 2022
    This next one will help us reduce final bundle size by minifying the generated code. It's called rollup-plugin-terser and uses terser under the hood to minify the code.
  • I reduced an npm package size by 50% with minification
    2 projects | | 27 Sep 2022
    fifty-three kilo-byte was a little bit large, and since the bundler i'm using for this package is rollup.js, all ineeded to do was install the terser — a JavaScript compressor toolkit for ES6 mdash; plugin for rollup.
  • How to build tree-shakeable JavaScript libraries
    7 projects | | 14 Sep 2022
    You can see that the div function was copied “as is” and is not used in any way. When you run Webpack in production mode, it will remove this function. (Internally, Webpack relies on Terser for minification; Rollup performs tree-shaking and dead code elimination on its own.)
  • 📦 Bundle Node.js into single executable binary
    6 projects | | 20 Aug 2022
    However, using the ESM packaging format has one advantage than CJS: tree-shaking. Tree-shaking is the concept of removing unused code from a dependency. Tools: esbuild, parcel, webpack, rollup, terser.
  • Minify JavaScript Using Terser
    2 projects | | 8 Aug 2022
    Install terser using yarn or npm.
  • Writing your own module bundler
    2 projects | | 16 Apr 2022
    Thus we have written our own module bundler by following the rollup way. We can also support a few extra options like code minification and mangling by using terser, we can also support iife format by wrapping the bundle with an iife expression. Since this is a basic example on how a bundler works, I have skimmed through a few stuffs, but in practice module bundlers are quite complex and interesting to learn about.
  • Tilepieces
    3 projects | | 8 Apr 2022
    The project is built with itself, and uses some of the popular frontend libraries like codemirror and terser.To build a tilepieces application, read the instructions.
