@ -5,43 +5,90 @@ title: Getting Started
## Requirements
You will need **Node.js** >= 12 and a **PostgreSQL** >= 10 database instance to be able to run Unleash.
You will need:
When starting Unleash you must specify a database URI (can be set as environment variable DATABASE_URL) which includes a username and password, that have rights to migrate the database.
- [**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).
On startup _Unleash_ will perform necessary migrations if needed.
## Start Unleash server
## Start Unleash
### 1. The simplest way to get started:
```bash
$ npm install unleash-server -g
$ unleash -d postgres://unleash_user:password@localhost:5432/unleash -p 4242
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:
```
Unleash started on http://localhost:4242
```
### 2. Or programmatically:
### Option one - from a terminal/bash shell
You can also depend on unleash
```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:${unleash.app.get('port')}`,
);
});
```
npm install unleash-server -g
unleash -d postgres://unleash_user:password@localhost:5432/unleash -p 4242
```
Available unleash options include:
### Option two - from Node.js
1. Create a new folder/directory on your development computer.
2. From a terminal/bash shell, install the dependencies:
```
npm init
npm install unleash-server --save
```
3. Create a file called *server.js*, paste the following into it and save.
```js
const unleash = require('unleash-server');
unleash
.start({
databaseUrl: 'postgres://unleash_user:password@localhost:5432/unleash',
port: 4242,
})
.then(unleash => {
console.log(
`Unleash started on http://localhost:${unleash.app.get('port')}`,
);
});
```
4. Run *server.js*:
```
node server.js
```
### Option three - use Docker
Launch the [Unleash server Docker image](https://hub.docker.com/r/unleashorg/unleash-server/).
```
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": {}\
}\
]\
}'\
~~~
<!-- The following doesn't seem to fit the 'remit' of Getting started'. it would be a better fit in the developer section of the documentation -->
## Unleash server options
Available Unleash options include:
- **db** - The database configuration object taking the following properties:
- _user_ - the database username (`DATABASE_USERNAME`)
@ -70,9 +117,9 @@ Available unleash options include:
- **baseUriPath** (string) - use to register a base path for all routes on the application. For example `/my/unleash/base` (note the starting /). Defaults to `/`. Can also be configured through the environment variable `BASE_URI_PATH`.
- **secureHeaders** (boolean) - use this to enable security headers (HSTS, CSP, etc) when serving Unleash from HTTPS. Can also be configured through the environment variable `SECURE_HEADERS`.
#### Disabling Auto-Start
### Disabling Auto-Start
If you're using unleash as part of a larger express app, you can disable the automatic server start by calling `server.create`. It takes the same options as `sevrer.start`, but will not begin listening for connections.

### 3. Docker
You can also use the [hosted docker image](https://hub.docker.com/r/unleashorg/unleash-server/) to start the Unleash server
```sh
docker run -d -e DATABASE_URL=postgres://user:pass@10.200.221.11:5432/unleash unleashorg/unleash-server
```
## Securing Unleash
Unleash also have extension points where you can integrate Unleash with your authentication provider (OAuth 2.0). Read more about [securing unleash](./securing-unleash.md).
