This Chrome Web extension reads the game Journal and allows websites to read it without other tools.

As a website developer, you should look at the 'examples' folder to understand how communication works between the background, content and page scripts.

The extension will inject itself into the active tab once the user clicks the extension icon in the browser.

Retrieving journal events is as simple as the following:

window.addEventListener("message", (event) => {
    if (event.data.source === 'Elite Journal Connector') { // Always check this
        switch (event.data.command) {
            case 'loading': // This event is the first message, extension is injected into the page.
                break;
            case 'loaded': // The extension has finished loading initial Journal data.
                break
            case 'journal': // Any Journal event
                if (this.loaded || this.fullJournal && !this.loaded)
                    this.parseEvent(event.data.event)
                break;
        }
    }
})

Web page listens for extension injection using window.addEventlistener

Extension injects (content script) and sends a message (content script) to the web page (page script) using window.postMessage

It also waits (content script) for commands from the web page, for example to fetch all journal data

Web page (script page) receives the message and asks for initial journal data using window.postMessage (sent to content)

Content then asks background to get the data and background sends it back as a whole.
