## About Unleash
|
|
|
|
Unleash is an open source feature management solution. It improves the workflow of your development team and leads to quicker software delivery. Unleash increases efficiency and gives teams _full control_ of how and when they enable new functionality for end users. Unleash lets teams ship code to production in _smaller_ releases _whenever_ they want.
|
|
|
|
Feature toggles make it easy to test how your code works with real production data without the fear that you'll accidentally break your users' experience. It also helps your team work on multiple features in parallel without each maintaining an separate feature branch.
|
|
|
|
Unleash is the largest open source solution for feature flagging on GitHub. There's 12 official client and server SDKs and 10+ community SDKs available; you can even make your own if you want to. You can use Unleash with any language and any framework.
|
|
|
|
<br/>
|
|
|
|
## Get started in 2 steps
|
|
|
|
### 1. Start Unleash
|
|
|
|
With [`git`](https://git-scm.com/) and [`docker`](https://www.docker.com/) installed, it's easy to get started:
|
|
|
|
Run this script:
|
|
|
|
```bash
|
|
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](./CONTRIBUTING.md#how-to-run-the-project).
|
|
|
|
### 2. Connect your SDK
|
|
|
|
Find your preferred SDK in [our list of official SDKs](#unleash-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`
|
|
- For server-side SDKs, use:
|
|
- Unleash API URL: `http://localhost:4242/api/`
|
|
- API token: `default:development.unleash-insecure-api-token`
|
|
|
|
If you use a different setup, your configuration details will most likely also be different.
|
|
|
|
### Check a feature toggle
|
|
|
|
Checking the state of a feature toggle 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 toggle is available. Here's how it might look in Java:
|
|
|
|
```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](https://docs.getunleash.io/reference/deploy/getting-started), [Unleash configuration options](https://docs.getunleash.io/reference/deploy/configuring-unleash), or [running Unleash locally via docker](https://docs.getunleash.io/tutorials/quickstart#i-want-to-run-unleash-locally).

## Unleash SDKs
|
|
|
|
To connect your application to Unleash you'll need to use a client SDK for your programming language.

## Migration guides
|
|
|
|
Unleash has evolved significantly over the past few years, and we know how hard it can be to keep software up to date. If you're using the current major version, upgrading shouldn't be an issue. If you're on a previous major version, check out the [Unleash migration guide](https://docs.getunleash.io/deploy/migration_guide)!
