## What Delete static client-side SDK docs in favor of generating them at build time. - Add a separate list of `clientSideSdks` to `readme-fns`. - Use sdk type to determine which generation directory it goes into - Replace manual sidebar category with autogenerated one ## Why This does the same for client-side SDKs as was done for server-side SDKs in https://github.com/Unleash/unleash/pull/2858 (Supersedes #2859)

The [Unleash Proxy](../reference/unleash-proxy.md) provides a way for you to consume feature toggles in [front-end clients](../reference/sdks/index.md#front-end-sdks), such as the [JavaScript Proxy client](/docs/generated/sdks/client-side/javascript-browser.md) and [React Proxy client](/docs/generated/sdks/client-side/react.md).
|
|
|
|
Depending on your setup, the Proxy is most easily run in one of two ways, depending on your situation:
|
|
|
|
- [Via Docker](#run-proxy-via-docker)
|
|
- [As a Node.js app](#run-proxy-as-node-app)
|
|
|
|
If you're using a hosted version of Unleash, we can also run the proxy for you.
|
|
|
|
## Prerequisites
|
|
|
|
This is what you need before you can run the proxy:
|
|
|
|
- A running Unleash server to connect to. You'll need its API path (e.g. `https://app.unleash-hosted.com/demo/api`) to connect the proxy to it.
|
|
- A [client API token](../reference/api-tokens-and-client-keys#client-tokens) for the proxy to use.
|
|
- If you're running the Proxy via Docker: [the `docker` command line tool](https://www.docker.com/).
|
|
- If you're running the Proxy as a Node.js app: [Node.js and its command line tools](https://nodejs.org/).
|
|
- A [Proxy client key](../reference/api-tokens-and-client-keys#proxy-client-keys). This can be any arbitrary string (for instance: `proxy-client-key`). Use this key when connecting a client SDK to the Proxy.
|
|
|
|
## How to run the Proxy via Docker {#run-proxy-via-docker}
|
|
|
|
We provide a [Docker image (available on on Docker Hub)](https://hub.docker.com/r/unleashorg/unleash-proxy) that you can use to run the proxy.
|
|
|
|
### 1. Pull the Proxy image
|
|
|
|
Use the `docker` command to pull the Proxy image:
|
|
|
|
```bash title="Pull the Unleash Proxy docker image"
|
|
docker pull unleashorg/unleash-proxy
|
|
```
|
|
|
|
### 2. Start the Proxy
|
|
|
|
When running the Proxy, you'll need to provide it with at least the configuration options listed below. Check the reference docs for the [full list of configuration options](../reference/unleash-proxy.md#configuration-options).
|
|
|
|
```bash title="Run the Unleash Proxy via Docker"
|
|
docker run \
|
|
-e UNLEASH_PROXY_CLIENT_KEYS=<proxy-client-key> \
|
|
-e UNLEASH_URL='<unleash-api-url>' \
|
|
-e UNLEASH_API_TOKEN=<client-api-token> \
|
|
-p 3000:3000 \
|
|
unleashorg/unleash-proxy
|
|
```
|
|
|
|
If the proxy starts up successfully, you should see the following output:
|
|
|
|
```bash
|
|
Unleash-proxy is listening on port 3000!
|
|
```
|
|
|
|
## How to run the Proxy as a Node.js app {#run-proxy-as-node-app}
|
|
|
|
To run the Proxy via Node.js, you'll have to create your own Node.js project and use the Unleash Proxy as a dependency.
|
|
|
|
### 1. initialize the project
|
|
|
|
If you don't already have an existing Node.js project, create one:
|
|
|
|
```bash npm2yarn
|
|
npm init
|
|
```
|
|
|
|
### 2. Install the Unleash Proxy package
|
|
|
|
Install the Unleash Proxy as a dependency:
|
|
|
|
```shell npm2yarn
|
|
npm install @unleash/proxy
|
|
```
|
|
|
|
### 3. Configure and start the proxy
|
|
|
|
Import the `createApp` function from `@unleash/proxy` and configure the proxy. You'll need to provide at least the configuration options highlighted below. Check the reference docs for the [full list of configuration options](../reference/unleash-proxy.md#configuration-options).
|
|
|
|
Here is an example of what running the Proxy as a Node.js app might look like:
|
|
|
|
```js title="Sample app running the Unleash Proxy"
|
|
const port = 3000;
|
|
|
|
const { createApp } = require('@unleash/proxy');
|
|
|
|
const app = createApp({
|
|
// highlight-start
|
|
unleashUrl: '<unleash-api-url>',
|
|
unleashApiToken: '<client-api-token>',
|
|
clientKeys: ['<proxy-client-key>'],
|
|
proxyPort: 3000,
|
|
// highlight-end
|
|
});
|
|
|
|
app.listen(port, () =>
|
|
console.log(`Unleash Proxy listening on http://localhost:${port}/proxy`),
|
|
);
|
|
```
|
|
|
|
## Verify that the proxy is working
|
|
|
|
When the proxy process has started up correctly, you can start querying its `/proxy` endpoint. If it's running correctly, you'll get back a JSON object with a list of toggles. The list may be empty if you haven't added any toggles for the corresponding project/environment yet.
