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.
