## Requirements
|
|
|
|
You will need:
|
|
|
|
- [**Node.js**](https://nodejs.org/en/download/) (version 12 or later)
|
|
- [**PostgreSQL**](https://www.postgresql.org/download/) (version 10 or later)
|
|
- [Create an unleash user and database](./developer-guide.md).
|
|
|
|
## Start Unleash server
|
|
|
|
Whichever option you choose to start Unleash, you must specify a database URI (it can be set in the environment variable DATABASE_URL).
|
|
|
|
Once the server has started, you will see the message:
|
|
|
|
```sh
|
|
Unleash started on http://localhost:4242
|
|
```
|
|
|
|
### Option one - from a terminal/bash shell
|
|
|
|
```sh
|
|
npm install unleash-server -g
|
|
unleash -d postgres://unleash_user:password@localhost:5432/unleash -p 4242
|
|
```
|
|
|
|
### Option two - from Node.js
|
|
|
|
1. Create a new folder/directory on your development computer.
|
|
2. From a terminal/bash shell, install the dependencies:
|
|
|
|
```sh
|
|
npm init
|
|
npm install unleash-server --save
|
|
```
|
|
|
|
3. Create a file called _server.js_, paste the following into it and save.
|
|
|
|
```js
|
|
const unleash = require('unleash-server');
|
|
|
|
unleash
|
|
.start({
|
|
databaseUrl: 'postgres://unleash_user:password@localhost:5432/unleash',
|
|
port: 4242,
|
|
})
|
|
.then(unleash => {
|
|
console.log(
|
|
`Unleash started on http://localhost:${unleash.app.get('port')}`,
|
|
);
|
|
});
|
|
```
|
|
|
|
4. Run _server.js_:
|
|
```sh
|
|
node server.js
|
|
```
|
|
|
|
### Option three - use Docker
|
|
|
|
Launch the [Unleash server Docker image](https://hub.docker.com/r/unleashorg/unleash-server/).
|
|
|
|
```sh
|
|
docker run -d -e DATABASE_URL=postgres://user:pass@10.200.221.11:5432/unleash unleashorg/unleash-server
|
|
```
|
|
|
|
## Test your server and create a sample API call
|
|
|
|
Once the Unleash server has started, go to [localhost:4242](http://localhost:4242) in your browser. If you see a list of example feature toggles, try modifying one of them with [curl](https://curl.se/) from a terminal/bash shell:
|
|
|
|
```
|
|
curl --location --request PUT 'http://localhost:4242/api/admin/features/Feature.A' --header 'Content-Type: application/json' --data-raw '{\
|
|
"name": "Feature.A",\
|
|
"description": "Dolor sit amet.",\
|
|
"type": "release",\
|
|
"enabled": false,\
|
|
"stale": false,\
|
|
"strategies": [\
|
|
{\
|
|
"name": "default",\
|
|
"parameters": {}\
|
|
}\
|
|
]\
|
|
}'\
|
|
```
