# VSCode Prettier Support #

It would be great if there was an easy way to formate .abell files on save with .prettierrc

**Describe the solution you'd like**

VSCode `settings.json`
```
"[javascriptabell]": {
"editor.formatOnSave": true
}
```

`.prettierrc`
```
{
"semi": false,
"singleQuote": true,
"trailingComma": "all",
"tabWidth": 2,
"useTabs": false,
"bracketSpacing": true
}
```
