has-require-or-import

Check if code requires/imports any module or a specific id

A fork of has-require by Ben Drucker. (Thanks Ben!)

Installing

$ npm install --save has-require-or-import

Usage

var hasRequire = require('has-require-or-import')
hasRequire('require("foo")', 'foo') // => true
hasRequire('import foo from "bar"', 'bar') // => true
hasRequire.any('require') // => false

API

For full implementation details, see the Checker API.

hasRequire(code, id) -> boolean

code

Required
Type: string

The code to check.

id

Required
Type: string

The module id to check, e.g. 'http'.

hasRequire.any(code) -> boolean

code

Required
Type: string

The code to check.

---

Checker

new hasRequire.Checker(code) -> checker

code

Required
Type: string

The code to store on the checker.

checker.any() -> boolean

Checks if any string literal is required. The result is cached. The following code won't be matched:

• require
• require()
• require('')

checker.has(id) -> boolean

id

Required
Type: string

The module id to check, e.g. 'http'.

Uses checker.any() first, so calling has for multiple ids when no require is present (!checker.any()) will avoid needlessly re-testing the code.
