passlint

passlint

Quickly check syntax errors with acorn ( syntax-error ) - if this fails your code is definitely not going to work, probably.

Default ECMAScript version is 6 ( 2015 ) - change it with -e <number> argument variable

Easy to use

passlint **/*.js && echo 'no errors was found'

Example

passlint **/*.js
  components/mics.js:245:7: Unexpected token
  js/admin-controller.js:2:1: Unexpected token

API

var passlint = require( 'passlint' )
var defaultEcmaVersion = 6 // 2015
var errline = passlint( 'test/output.js', defaultEcmaVersion )
if ( errline ) console.error( errline )

  test/output.js:484:40: ParseError: Unexpected token

Arguments

$ passlint --help
Usage: passlint [optinos]

Arguments:

--ecma-version, -e <number>     specify ecma version to check against
                                defaults to 6 ( 2015 )

                                example: `passlint -e 6 src/**`

--version, -V                   print version and exit

--help, -h                      help ( this text )

Install

locally ( project specific, for use with npm scripts )

npm install passlint

globally

npm install -g passlint

Why

To quickly capture absolutely essential errors. Some projects have messy or no linting rules at all. Even with linting setup not everything gets fixed or gets forgotten.

passlint is the dirty final gate that needs to be passed for your code to run regardless of style rules.

Alternatives

You can use node's -c flag for similar functionality. Note the variablity between node versions, passlint tests against ES 2015 by default and also formats the output more concisely.

node -c **/*.js
