Bookmarkleter

You have JavaScript. You need a bookmarklet. This does that.

Browser tool

Create bookmarklets in your browser with a simple copy and paste.

npm install --save bookmarkleter

const bookmarkleter = require( 'bookmarkleter' );
const bookmarklet = bookmarkleter( code, options );

All options are Boolean flags.

urlencode (default true): URL-encode reserved characters: [space], %, ", <, >, #, @, &, ?
iife (default false): Wrap in an IIFE (anonymizing function) to prevent exposing variables to the page on which the bookmarklet is running.
minify (default false): Minify using babel-minify to reduce the size of the bookmarklet.
transpile (default false): Transpile to ES5 using Babel.
jQuery (default false): Make sure a modern version (>= 1.7) of jQuery is available for your code.

This is free software. It is released to the public domain without warranty.
