ignore-if

A higher-order function that allows you to ignore higher-order function when a condition is met, such as NODE_ENV === 'test'.

Installation

$ npm install --save-dev ignore-if

Usage

One use case for this is in React when you want to wrap your component in a higher-order component, but you'd like to ignore the wrapper in testing. This is useful for things like react-css-modules.

import cssModules from 'react-css-modules'
import ignoreIf from 'ignore-if'
import styles from './styles.css'
 
class MyComponent {
  render() {
    return <div></div>
  }
}
 
const isTest = process.env.NODE_ENV === 'test'
 
export default ignoreIf(isTest, cssModules(MyComponent, styles)))

Automatically Curried

If you omit the second argument, the wrapper, ignoreIf will automatically return a curried function that allows you to call it again with the second argument:

import cssModules from 'react-css-modules'
import ignoreIf from 'ignore-if'
import styles from './styles.css'
 
const ignoreIfTest = ignoreIf(process.env.NODE_ENV === 'test')
 
class MyComponent {
  render() {
    return <div></div>
  }
}
 
export default ignoreIfTest(cssModules(MyComponent, styles)))

Compose and Pipe

You can use this tool easily with compose() or pipe() from functional libraries like Ramda:

import {pipe} from 'ramda'
import connect from 'react-redux'
import cssModules from 'react-css-modules'
import ignoreIf from 'ignore-if'
import styles from './styles.css'
 
const ignoreIfTest = ignoreIf(process.env.NODE_ENV === 'test')
 
class MyComponent {
  render() {
    return <div></div>
  }
}
 
export default pipe(
  ignoreIfTest(cssModules(styles)),
  connect()
)(MyComponent)
