О чём код?
/* global chrome */ let lastSentDevToolsHookMessage; // We want to detect when a renderer attaches, and notify the "background page" // (which is shared between tabs and can highlight the React icon). // Currently we are in "content script" context, so we can't listen to the hook directly // (it will be injected directly into the page). // So instead, the hook will use postMessage() to pass message to us here. // And when this happens, we'll send a message to the "background page". window.addEventListener('message', function onMessage({data, source}) { if (source !== window || !data) { return; } // We keep this logic here and not in `proxy.js`, because proxy content script is injected later at `document_end` if (data.source === 'react-devtools-hook') { const {source: messageSource, payload} = data; const message = {source: messageSource, payload}; lastSentDevToolsHookMessage = message; chrome.runtime.sendMessage(message); } }); // NOTE: Firefox WebExtensions content scripts are still alive and not re-injected // while navigating the history to a document that has not been destroyed yet, // replay the last detection result if the content script is active and the // document has been hidden and shown again. window.addEventListener('pageshow', function ({target}) { if (!lastSentDevToolsHookMessage || target !== window.document) { return; } chrome.runtime.sendMessage(lastSentDevToolsHookMessage); });
