Google Chrome extension (Fire a event when extension starts)

Question

I want to fire a event just when my chrome extension starts. How do I achieve this? Is there a event listener that triggers when extension starts?

for example:-

chrome.runtime.onInstalled.addListener(function(){
        console.log('i will run once!');
});

Similar to this but not on installed but on start and it should only fire once during the extension's run time which is when it starts.

You could use an onload event in your background page and put the code that you want to be executed on extension "start-up" in there.

Example (inside background.js):

window.onload = function() {
  console.log("Extension has started...");
};

That message will be logged (once) when:

• Extension is installed
• Chrome is started (and extension is enabled)
• Extension is enabled from disabled state
