jsxhint

Wrapper for JSHint to allow hinting of JSX files

#JSXHint A wrapper around JSHint to allow linting of files containing JSX syntax.

Accepts the same input and JSHint and emits the same output. Switches sent to jsxhint are forwarded on to jshint.

Glob parsing, ignores, and jshintrc parsing are all performed by jshint.

Automatically lints all files with the .js and .jsx extensions.

##Rationale

This module is intended for use as part of SublimeLinter-jsxhint, but it can be used separately as a smart replacement for JSHint. It will automatically convert any file with the jsx extension into JS using react-tools, then present the file to JSHint for validation.

Note that as of React 0.12, it is recommended to use the .jsx file extension rather than the pragma in .js files. If you are already using the .jsx extension, add the option --jsx-only. This will skip attempted conversion of .js files to JSX, but still lint those files. This is useful for running an entire project.

JSXHint is safe to use as a drop-in replacement for JSHint, even when JSX files are not present in a project.

JSXHint offers a simple workflow that accepts JSX files without modification. Additionally, JSXHint actually lints the object definitions generated by the JSX compiler, allowing you to catch mistakes in your templates (such as undefined variables, syntax errors, and missing modules).

JSXHint cli allows for pattern arrays via glob-all

##Examples

# Lint entire project. JSXHint will only lint .js and .jsx files.
jsxhint .
 
# Lint files in `src` folder only.
jsxhint src
 
# Lint Project using only `.jsx` extension for JSX.
# Will lint .js files with jshint, .jsx files with jsxhint.
jsxhint --jsx-only .
 
# Basic globbing
jsxhint --config ./other-directory/.jshintrc src/foo/*.jsx
 
# Multiple patterns
jsxhint 'jsx/**/*' '!scripts/**/*' 'scripts/outlier.jsx'
 
# Common multiple patterns usecase - lint .js and .jsx, ignore modules and build
jsxhint '**/*.js*' '!node_modules/**/*' '!build/**/*'
 
# Accepts stdin with '-'
jsxhint - < src/file.jsx
 
# Exclude files
jsxhint --exclude excludeme.jsx src/foo/*.jsx
 
# Lint project using babel (previously 6to5)
# Note that you must explicitly install `babel` if you wish to use it.
jsxhint --babel src
