PHP's addslashes in TypeScript

How to use

Install via yarn add locutus and import: import { addslashes } from 'locutus/php/strings/addslashes'.

Or with CommonJS: const { addslashes } = require('locutus/php/strings/addslashes')

Use a bundler that supports tree-shaking so you only ship the functions you actually use. Vite, webpack, Rollup, and Parcel all handle this. For server-side use this is less of a concern.

Examples

These examples are extracted from test cases that automatically verify our functions against their native counterparts.

#	code	expected result
1	addslashes("kevin's birthday")	"kevin\\'s birthday"

Here's what our current TypeScript equivalent to PHP's addslashes looks like.
