Zero config JavaScript/TypeScript runner
right in your terminal
## 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:
1. Reads the current directory and lets you choose a file.
2. Transpiles the file and produces a valid JavaScript bundle. It uses [Rollup](https://rollupjs.org/) so it does resolve your imports.
3. Runs the generated bundle via node and shows you the result.
4. 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](https://codesandbox.io/) and [CodePen](https://codepen.io/) 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.
More about the story here [https://krasimirtsonev.com/blog/article/hopa-javascript-typescript-runner](https://krasimirtsonev.com/blog/article/hopa-javascript-typescript-runner).
## 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.`. Have in mind that this feature is experimental. I find that in some cases Hopa can't resolve properly modules and errors out.
