Apollo Client Devtools

Download for Firefox | Download for Chrome

This repository contains the Apollo DevTools extension for Chrome & Firefox.

If you are running Apollo Client 2.0, the dev tools require at least apollo-client@2.0.0-rc.2 and react-apollo@2.0.0-beta.0, and you must be running at least version 2.0.5 of the dev tools themselves.

If you are running Apollo Client 3.0, you must be running at least version 2.3.1 of the dev tools.

The devtools no longer work with Apollo Client 1.0, but upgrading should be relatively easy! If it isn't, please reach out on the Apollo Spectrum

Code of Conduct

This project is governed by the Apollo Code of Conduct

Features

The devtools appear as an "Apollo" tab in your Chrome inspector, along side the "Elements" and "Console" tabs. There are currently 3 main features of the devtools:

  • GraphiQL: Send queries to your server through the Apollo network interface, or query the Apollo cache to see what data is loaded.
  • Normalized store inspector: Visualize your GraphQL store the way Apollo Client sees it, and search by field names or values.
  • Watched query inspector: View active queries and variables, and locate the associated UI components.

GraphiQL Console

Make requests against either your app’s GraphQL server or the Apollo Client cache through the Chrome developer console. This version of GraphiQL leverages your app’s network interface, so there’s no configuration necessary — it automatically passes along the proper HTTP headers, etc. the same way your Apollo Client app does.

Store Inspector

View the state of your client-side cache as a tree and inspect every object inside. Visualize the mental model of the Apollo cache. Search for specific keys and values in the store and see the path to those keys highlighted.

Watched Query Inspector

View the queries being actively watched on any given page. See when they're loading, what variables they're using, and, if you’re using React, which React component they’re attached to. Angular support coming soon.

Installation

You can install the extension via Firefox Browser Add-ons or the Chrome Webstore. If you want to install a local version of the extension instead, skip ahead to the Developing section.

Configuration

While your app is in dev mode, the devtools will appear as an "Apollo" tab in your chrome inspector. To enable the devtools in your app even in production, pass connectToDevTools: true to the ApolloClient constructor in your app. Pass connectToDevTools: false if want to manually disable this functionality.

The "Apollo" tab will appear in the Chrome console if there exists a global window.__APOLLO_CLIENT__ object in your app. Apollo Client adds this hook to the window automatically unless process.env.NODE_ENV === 'production'. If you would like to use the devtools in production, just manually attach your Apollo Client instance to window.__APOLLO_CLIENT__ or pass connectToDevTools: true to the constructor.

If you're seeing the "Apollo" tab but still having issues, skip ahead to the Developing: Debugging section.

Developing

Installation

After cloning this repo, compile the extension bundle:

cd apollo-client-devtools
npm install
npm run build

Install the extension in Chrome:

  • Open chrome://extensions
  • Enable the 'Developer Mode' checkbox
  • Click 'Load unpacked extensions...'
  • Select the apollo-client-devtools/shells/webextension folder

Now, while on any page, open the chrome inspector. If you're inspecting a page that is using Apollo Client, there will be a global window.__APOLLO_CLIENT__ object on that page. If that object exists, you will see an "Apollo" tab in the inspector menu. This tab will contain the Apollo Client devtools.

Folder structure

The extension is built using React and ES6. All the main source code for the devtools exists in the /src folder, with devtools/components/Panel.js being the container component, and index.js attatching the Panel to the document itself. If you're interested in editing the current code or adding a new feature, you would do so here.

Since the devtools are designed to work in multiple environments, the /shells folder is where each environment is setup. The one for chrome and firefox live under webextension. Wepback bundles the code from the /src into /shells/webextension/dist when building for chrome for example. To load the extension locally, you would load from this folder. Likewise, to upload the extension to the Chrome Webstore, you would upload a zip of this folder.

The root of the repo contains the .bablerc file, webpack config file, and necessary package.json.

Reloading the Chrome extension

Unfortunately, there is no way to hot-reload a Chrome extension in the inspector while developing it.

While actively working on the devtools, you should run npm run chrome in the devtools repo. This will have webpack watch your files, and rebundle them automatically whenever you make a change. With webpack -w running, you'll simply have to close the chrome inspector and open it again to see your changes in effect (no need to hit reload on the chrome://extensions page unless you make a change to the extension manifest).

Developing with hot reload in an app

Working within a specific browser's extension environment can be a less than ideal development experience. To make this better, we have created a local shell with hot reloading to try out features. To run this, run npm run dev and go to the local app.

Note: While great for expedited development of layout and CSS, this method doesn't allow you to simulate the environment of a chrome extension perfectly. Thus, we recommend you use a combination of both this process and the one described in the previous section while working on the extension. Make sure to test any major changes in the final environment.

Debugging

If there is an error in the devtools panel, you can inspect it just like you would inspect a normal webpage. Detach the inspector console from the window (if it's not already detached) by clicking the button with three vertical dots in the upper right corner of the console and selecting the detach option. With the detached console in focus, press opt-cmd-I again to open an inspector for the detached console (inspector inception). In this new inspector, you will be able to inspect elements in the first inspector, including the Apollo dev tools panel.

If you are using Apollo Client 2.0, make sure you are using at least version 2.0.5 of the devtools.

If you are using Apollo Client 3.0, make sure you are using at least version 2.3.1 of the devtools.

If you're seeing an error that's being caused by the devtools, please open an Issue on this repository with a detailed explanation of the problem and steps that we can take to replicate the error.

Prior Art

Special thanks goes out to the Vue devtools and in particular the help of Guillaume Chau (@Akryum) who has been an incredible part of the Apollo community. The continued progress of this tool wouldn't be possible without his guidance and help.

Publishing

Release process, for those with permission:

  1. Commit changes, update the manifest.json version number where needed, and tag your version release.
  2. Verify that your changes work as expected by loading the extension as an "unpacked extension" locally for each browser.
  3. Merge changes and version tag to master.
  4. Run npm run zip to pack all of the builds for submission.
  5. Make sure the version used in manifest.json is also used in package.json, and publish a new version to npm using npm publish in the root of the project. We're publishing to npm to allow other projects to have a dependency on devtools.
  6. Create a new release in the Chrome/Firefox web stores (following the instructions for each browser in the sections below), uploading the new zip folder.

Chrome

TODO

Firefox

  1. Login to the Firefox developer hub (user/pass is in our shared password system as "Firefox Developer Account").
  2. Once logged in, click on the Apollo Client Developer Tools "Edit Product Page" link.
  3. Click on the "Upload New Version" link in the top left side menu.
  4. Agree to any new Firefox distribution agreements or policies that might show up.
  5. When the "Submit a New Version" page shows, click on the file upload button in the "Upload Version" section (keeping "Firefox" as the only option checked in the compatible application section).
  6. Choose the apollo-client-devtools/dist/apollo_client_developer_tools-X.X.X.zip for upload and submit.
  7. After the file has been validated, continue with the submission.
