Extracts the Avatar Group component into a `common` component and adds a standard tooltip to all avatars. Relates to linear issue 1-2606 This is a suggestion / proof of concept for how we can solve it. While I think we can merge this as is, I'd also be happy to take any discussions on other ways to approach it etc. ## Why are these changes made together? Because extracting the avatar group without adding the new tooltip data made the existing tooltip misbehave (it'd show up in the top left of the screen, not synced to the avatar in any way). I probably could have (and still can if you think it's prudent) split it out such that the avatar gets a standardized tooltip first (and disable it for the group card avatars), and split out the avatars in a follow-up. Happy to do that if you think it's better. ## What does this mean? It used to be that we had no consistent way of dealing with avatars and tooltips. Some places had them, some places didn't. This change makes it so that all avatars that we can show tooltips for will get the same tooltip. Previously, we had at least 4 different ways of dealing with tooltips: - The HTML tooltip (that would be standardized with this PR) in the project flags table  - The "title" that you'd get on your user avatar  - The group card list tooltip  - And sometimes you'd get nothing at all  with this change, we'll always show the same kind of tooltip if we can:  ## What goes in the tooltip? We use the `UserAvatar` component for a fair few different things and I didn't want to extract separate components for all the different use cases. Instead, I wanted to get an overview over what we use it for and what is relevant info to show. I found all the places we used it and tried to form an opinion. This tooltip will work with a user's email, name, username, and id. If there is no user (such as for empty avatars and avatars displaying only "+n" for remaining members), we show no tooltip. Following the example set by the group card avatars, we'll try to use email or username (in that order) as the main bit of text. If the user has an email or a username and also a name, the name will be used as secondary text. If the user does not have an email or username, but has a name, we'll use the name as the main text. If the user does not have an email, a username, or a name, we'll try to show "User ID: N" if they have an id. If they do not have a username, a name, an email, or an ID, we bail out and show nothing. ## Why can you disable the tooltip? In some cases, you might want to disable the tooltip because you have more information to feed into it. An example of that is in the project flags table, where we want to show more information in cases where the user is 'unknown':  ## Additional fixes This PR also adds a few lines of CSS to fix a minor avatar layout bug.

What is Unleash?
Unleash is a powerful open source solution for feature management. It streamlines your development workflow, accelerates software delivery, and empowers teams to control how and when they roll out new features to end users. With Unleash, you can deploy code to production in smaller, more manageable releases at your own pace.
Feature flags in Unleash let you test your code with real production data, reducing the risk of negatively impacting your users' experience. It also enables your team to work on multiple features simultaneously without the need for separate feature branches.
Unleash is the most popular open source solution for feature flagging on GitHub. It supports 15 official client and server SDKs and over 15 community SDKs. You can even create your own SDK if you wish. Unleash is compatible with any language and framework.
Getting Started with Unleash
1. Setting Up Unleash
To get started with Unleash, you need git and docker installed on your machine.
Execute the following commands:
git clone git@github.com:Unleash/unleash.git
cd unleash
docker compose up -d
Then point your browser to localhost:4242 and log in using:
- username:
admin - password:
unleash4all
If you'd rather run the source code in this repo directly via Node.js, see the step-by-step instructions to get up and running in the contributing guide.
2. Connect your SDK
Find your preferred SDK in our list of official SDKs and import it into your project. Follow the setup guides for your specific SDK.
If you use the docker compose file from the previous step, here's the configuration details you'll need to get going:
- For front-end SDKs, use:
- URL:
http://localhost:4242/api/frontend/ clientKey:default:development.unleash-insecure-frontend-api-token
- URL:
- For server-side SDKs, use:
- Unleash API URL:
http://localhost:4242/api/ - API token:
default:development.unleash-insecure-api-token
- Unleash API URL:
If you use a different setup, your configuration details will most likely also be different.
Check a feature flag
Checking the state of a feature flag in your code is easy! The syntax will vary depending on your language, but all you need is a simple function call to check whether a flag is available. Here's how it might look in Java:
if (unleash.isEnabled("AwesomeFeature")) {
// do new, flashy thing
} else {
// do old, boring stuff
}
Run Unleash on a service?
If you don't want to run Unleash locally, we also provide easy deployment setups for Heroku and Digital Ocean:
Configure and run Unleash anywhere
The above sections show you how to get up and running quickly and easily. When you're ready to start configuring and customizing Unleash for your own environment, check out the documentation for getting started with self-managed deployments, Unleash configuration options, or running Unleash locally via docker.
