Ember Inspector

Adds an Ember tab to the browser's Developer Tools that allows you to inspect Ember objects in your application.

Installation

Chrome

Install the extension from the Chrome Web Store.

OR:

• Clone the repository
• cd into the repo directory
• run yarn install
• run yarn global add ember-cli
• run yarn build to build the dist directory
• Visit chrome://extensions in Chrome
• Make sure Developer mode is checked
• Click on 'Load unpacked extension...'
• Choose the dist/chrome folder in the cloned repo
• Close and re-open developer tools if it's already open

Firefox

Install the Firefox addon.

OR:

• Clone the repository
• cd into the repo directory
• run yarn install
• run yarn global add ember-cli
• run yarn build to build the dist directory
• Visit about:debugging in Firefox
• Click on 'Load Temporary Addon-on'
• Choose the dist/firefox/manifest.json file in the cloned repo

Opera

• Clone the repository

• run yarn install
• run yarn global add ember-cli
• run yarn build to build the dist directory
• Visit chrome://extensions in Opera
• Make sure Developer mode is checked
• Click on 'Load unpacked extension...'
• Choose the dist/chrome folder in the cloned repo
• Close and re-open developer tools if it's already open

Bookmarklet (All Browsers)

javascript: (function() { var s = document.createElement('script'); s.src = '//ember-extension.s3.amazonaws.com/dist_bookmarklet/load_inspector.js'; document.body.appendChild(s); }());

Internet explorer will open an iframe instead of a popup due to the lack of support for cross-origin messaging.

For development:

• run yarn serve:bookmarklet
• create a bookmark (make sure you unblock the popup when you run the bookmarklet):

javascript: (function() { var s = document.createElement('script'); s.src = 'http://localhost:9191/bookmarklet/load_inspector.js'; document.body.appendChild(s); }());

Building and Testing:

Run yarn install && yarn global add ember-cli && grunt-cli to install the required modules.

• yarn build to build the files in the dist directory
• yarn watch To watch the files and re-build in dist when anything changes (useful during development).
• yarn test To run the tests in the terminal
• yarn start To start the test server at localhost:4200/testing/tests

Deploy new version:

Patch versions

Patch versions are only committed to the stable branch. So we need to cherry-pick the commits we need from master and bump stable to the new patch version.

• git checkout stable
• Cherry-pick the needed commits from master to stable
• Bump the patch version in package.json. Add the change log entry and commit.
• Follow the "Steps to publish" below.
• git checkout master
• Commit the change log entry to the master branch.

Minor and major versions

When releasing a major/minor version, master would already have this version set, so what we need to do is to merge master into stable and release.

• Add the new minor/major version's change log entry in CHANGELOG.md and commit to master. We use github-changelog-generator for this. You will want to follow the installation instructions on their README, and take note that you will need to provide a GitHub token. Once installed, and you add a token, you can just run github_changelog_generator in your terminal.
• git checkout stable
• git merge -X theirs master
• Follow the "Steps to publish" steps below.
• git checkout master
• Update package.json to the future major/minor version.

Steps to publish

• Push the stable branch to github (this will publish the bookmarklet version).
• yarn build:production
• git tag the new version
• Follow the "Publishing to Chrome" steps
• Follow the "Publishing to Firefox" steps
• npm publish ./

Locking a version

We can take a snapshot of the current inspector version to support a specific Ember version range. This allows us to stop supporting old Ember versions in master without breaking the published inspector for old Ember apps. It works by serving a different inspector version based on the current app's Ember version.

The Ember versions supported by the current inspector are indicated in the emberVersionsSupported array in package.json.

Here are the steps to lock an inspector version:

• Update package.json's emberVersionsSupported: add a second element that indicates the minimum Ember version this inspector does not support.
• Release a new version (See "Minor and major versions"). Create a branch for this version.
• Run yarn lock-version. This will build, compress, and upload this version to S3.
• Update package.json's previousEmberVersionsSupported: add the first Ember version supported by the recently locked version (the first element in the emberVersionsSupported array).
• Update package.json's emberVersionsSupported: Move the second element in the array to the first position. Add an empty string as the second element to indicate there's currently no maximum Ember version supported yet.
• Commit.

Window Messages

The Ember Inspector uses window messages, so if you are using window messages in your application code, make sure you verify the sender and add checks to your event listener so as not to conflict with the inspector's messages.
