JavaScript O-Standard Style

Standard + react + .tsx support.

Based on and inspired by Flet/semistandard

Usage

The easiest way to use JavaScript O-Standard Style to check your code is to install it globally as a Node command line program. To do so, simply run the following command in your terminal (flag -g installs standard globally on your system, omit it if you want to install in the current working directory):

npm install ostandard -g

After you've done that you should be able to use the ostandard program. The simplest use case would be checking the style of all JavaScript files in the current working directory:

$ ostandard
Error: Use JavaScript Standard Style
  lib/torrent.js:950:11: Expected '===' and instead saw '=='.

Custom Parser

To use a custom parser, install it from npm (example: npm install babel-eslint) and add this to your package.json:

{
  "ostandard": {
    "parser": "babel-eslint"
  }
}

Vim

Install Syntastic and add these lines to .vimrc:

let g:syntastic_javascript_checkers=['standard']
let g:syntastic_javascript_standard_generic = 1
let g:syntastic_javascript_standard_exec = 'ostandard'
let g:syntastic_typescript_checkers=['standard']
let g:syntastic_typescript_standard_generic = 1
let g:syntastic_typescript_standard_exec = 'ostandard'

For automatic formatting on save, add these two lines to .vimrc:

autocmd bufwritepost *.js silent !ostandard % --fix
set autoread

Ignoring files

Just like in standard, The paths node_modules/**, *.min.js, bundle.js, coverage/**, hidden files/folders (beginning with .), and all patterns in a project's root .gitignore file are automatically excluded when looking for .js files to check.

Sometimes you need to ignore additional folders or specific minfied files. To do that, add a ostandard.ignore property to package.json:

"ostandard": {
  "ignore": [
    "**/out/",
    "/lib/select2/",
    "/lib/ckeditor/",
    "tmp.js"
  ]
}

Make it look snazzy

If you want prettier output, just install the snazzy package and pipe ostandard to it:

$ ostandard --verbose | snazzy

O stands for?

O is first letter of my id. Also sound like 'all', means JavaScript and TypeScript.
