Javascript syntax check plugin for vim

Javascript syntax check for vim

A vim plugin for checking javascript syntax error only.

It's build for speed, almost 6x faster than eslint on my machine.

It uses notifies functions from syntastic, the result looks like:

Hope it help to improve your experience with coding javascript.

Install

You should have node installed, it comes with npm command.

Add the plugin to your vim plugin management config, for example with Vundle

in your .vimrc:

" If you want to have notifies, [syntastic](https://github.com/scrooloose/syntastic) is needed
Plugin 'scrooloose/syntastic'
Plugin 'chemzqm/jscheck'

then install：

:so ~/.vimrc
:BundleInstall

You have to disable auto check of syntastic for syntastic to avoid syntastic check on file save:

let g:syntastic_mode_map = {
    \ "mode": "active",
    \ "passive_filetypes": ["javascript"] }

The plugin will prompt you to install the node dependencies only if they are not installed.

Usage

" Check current file content by command, no need to save
:JSCheck

" disable auto check for javascript files on save
let g:jscheck_no_autocheck = 1
