Making a Chrome Extension

The first part of making an extension for chrome is that you need the manifest file, so create a text file and name is manifest.json The manifest file basically says what your project is all about, and different things your project needs to run. Open the manifest file in a text editor and type in the “manifest_version”, you project name, it’s description, and it’s version…as such:

{ “manifest_version” : 2, “name” : “Pianobar Remote”, “description” : “Example chrome extension”, “version” : “1.0”,

Next you need to add the “browser_action” setting. This sets up your icon for the extension and the website that opens when you click on it.

“browser_action”: { “default_icon” : “icon.png”, “default_popup” : “popup.html” },

Finally, you need to setup the “permissions”. Currently we have no permissions that we need so will just put in a placeholder.

“permissions”:[ "“https://ajax.googleapis.com/” ] }

Next we will setup a simple popup.html file.

Finally you need to open up your chrome, click on the 3 bars, go to tools, extensions and select “Developer Mode”. Click load unpacked extension and open the folder where your extension is stored.
