Run JS ES6 & Reactjs in the browser.

While I was building a reactjs package and just after finishing it. I wanted to test it in browser - not just unit test! I was lazy to install webpack dev server or other tools to compile my code and run dev server with hot-reload, so I went to try running it directly in the browser! and yaay it worked! and here is few things I learned:

  • UMD - Universal Module Definition
  • AMD - Asynchronous Module Definition
  • CJS - CommonJS Modules
  • You can run es6 code in the browser with script type text/babel and include babel Stand alone in the browser to transpile your es6 code - so cool!
  • You can see how babel transpile your code just in the browser here:
  • You can include almost all the JS libraries directly in your browser with umd bundles.
  • Rollup and Typescript build is just so easy as 1-2-3! and there is 2 great literary starters
  • Being more inclined to be lazy is a good thing, as long as you use this to read and re-discover another ways to solve your problems.

  • Keeping up to date with tech is hard as tech moving at super speed and everyday there is always a new thing! so try as much as you can Un-learn and Re-learn things you were used to do before as there might be other solutions developed.
