Developing InstallationĪfter cloning this repo, install the required packages: If you are seeing the "Apollo" tab but are still having issues, skip ahead to the Debugging section. If you would like to use the devtools in production, manually attach your Apollo Client instance to window._APOLLO_CLIENT_ or pass connectToDevTools: true to the constructor. Apollo Client adds this hook to the window automatically unless _ENV = 'production'. The "Apollo" tab will appear in your web browser inspector if a global window._APOLLO_CLIENT_ object exists in your application. Pass connectToDevTools: false if want to manually disable this functionality. To enable the devtools for your application in production, pass connectToDevTools: true to the ApolloClient constructor in your application. While your application is in dev mode, the devtools will appear as an "Apollo" tab in your web browser inspector. If you want to install a local version of the extension instead, skip ahead to the Developing section. You can install the extension via Firefox Browser Add-ons or the Chrome Webstore. Cache inspector: Visualize the Apollo Client cache and search through it by field names and/or values.Mutation inspector: View fired mutations, variables, and re-run individual mutations.Watched query inspector: View active queries, variables, cached results, and re-run individual queries.GraphiQL: Send queries to your server through your web applications configured Apollo Client instance, or query the Apollo Client cache to see what data is loaded.The devtools currently have four main features: The Apollo Client Browser Devtools appear as an "Apollo" tab in your web browser inspector, alongside other tabs like "Elements" and "Console". This repository contains the Apollo Client Browser Devtools extension for Chrome & Firefox.

ĭocument.getElementById("remove").Download for Firefox | Download for Chrome In this example we have a list in the DOM, and assign the DOM element to a variable to change its styles. To do this, switch to the Memory tab in Chrome DevTools We can use a Heap Snapshot to detect them. The garbage collector can not remove them and they stay in memory. The garbage collectors of modern browsers will free up memory if a DOM node is no longer referenced, either by the DOM tree or by JavaScript code.ĭetached DOM nodes are nodes that are removed from the page but are still JavaScript referenced by JavaScript. Identify detached DOM nodes with the Heap Snapshot Memory consumption on the page returns to normal:

That's because we always push the same string onto the array, and storing the same string twice doesn't take any additional memory.Ĭlicking the Remove button clears up the array and removes the divs from the DOM. It rises after the first click, but not after. We see that the green graph is rising after every click, as more notes are added to the DOM.

Next, we click the button on our page several times and wait 2-3 seconds after each click. This way we ensure that anything that can be cleaned up is cleaned up by the JavaScript engine, rather than being cleaned up later and confusing our results. Navigate to the test page, open the DevTools performance tab, and hit the red Record icon.Ĭlick the garbage collection button (trash icon) to force a garbage collection.

Let's take this code snippet as an example: Click meĮvery time we click the "click me" button the script appends 10.000 nodes to the DOM and pushes a string consisting of million x characters onto the array. If we do this in a normal window the measurement data would include all browser extensions, making it harder to identify issues caused by our own code. Note that we use an Incognito window when measuring performance. To try this out, open the DevTools in Chrome and switch to the Performance tab. The performance profiler in Chrome can visualize memory usage and graph it over time. Visualize memory consumption with the performance profiler

In this article we'll explain how to debug JavaScript memory issues and look at some common problems. Memory leaks can hurt the performance of your website and even crash your page, especially on mobile devices.
