hopa v1.5.1
Features
- Zero configuration 🚀
- Transpiles and runs JavaScript and TypeScript ⚙️
- Single-folder file browser 📁
What and Why
Hopa is a command line tool that does the following:
- Reads the current directory and lets you choose a file.
- Transpiles the file and produces a valid JavaScript bundle. It uses Rollup so it does resolve your imports.
- Runs the generated bundle via node and shows you the result.
- It also runs a watcher so changing the files will trigger new compilation.
I did this little tool because I'm tired of creating dummy repos, copying webpack files, switching between terminal and browser just so I can run some "modern" JavaScript. I know about solution like CodeSandbox and CodePen but I want specifically to exercise my code in the terminal. And I want to do it quick, without configuring stuff like Babel and Webpack.

Installation
npm i hopa -g
Usage
Go to the folder that contains your files and run hopa
.
> hopa
This will display a menu and you have to pick a file. You'll get transpilation, bundling, running and watching.
> hopa -i script.js -o bundle.js -m
Gets script.js
, transpiles it and bundle it to a new file called bundle.js
which is also minified. No watching in this case. It's a single-shot operation. -m
and -o
are optional. If the output is not specified Hopa creates a file with name bundle.<your file>
. Have in mind that this feature is experimental. I find that in some cases Hopa can't resolve properly modules and errors out.
