Instalike Build Status npm version

Attractive, anonymous, globally-aware like buttons for anything. Simple embed an iframe in your website and it will use the public API. Or, you can self-host the API in order to add a custom like button to your nodejs project. You can use Instalike buttons to hold informal polls, to ask the internet for approval, and even to impress your friends.



There are 2 ways you can use Instalike: with the public API, or as a self-hosted node package.

Option 1: Use the public API

Place the <iframe> into your HTML, and specify a THING to keep track of. (Thing names are case-sensitive and can contain any Unicode characters.) That's it! The website will automatically use the public API to keep track of the like count for your "thing." Optionally, you can specify align=right to make the button right-aligned (default is left-aligned).

<iframe src="//" frameborder="0" scrolling="0" width="140px" height="20px">

API hosting provided by Cimpress. The API supports GET/POST/PATCH

Option 2: Host the API yourself

Install the npm module if you want to host the API yourself. This is perfect for on-premesis enterprise installations.

$ sudo npm install -g gulp
$ npm install instalike
$ redis-server & # or start it as a service
$ npm start

# Note: stop redis safely using redis-cli
$ redis-cli> shutdown
2002:M 20 Jul 16:50:13.137 # User requested shutdown...
2002:M 20 Jul 16:50:13.137 * Saving the final RDB snapshot before exiting.
2002:M 20 Jul 16:50:13.138 * DB saved on disk
2002:M 20 Jul 16:50:13.138 # Redis is now ready to exit, bye bye...
not connected> exit
Job 1, 'redis-server &' has ended
