# frontend
This directory contains the Unleash Admin UI frontend app.
## Run with a local instance of the unleash-api
Refer to the [Contributing to Unleash](../CONTRIBUTING.md#how-to-run-the-project) guide for instructions.
The frontend dev server runs (in port 3000) simultaneously with the backend dev server (in port 4242):
```
yarn install
yarn dev
```
## Run with a sandbox instance of the Unleash API
Alternatively, instead of running unleash-api on localhost, you can use a remote instance:
```
cd ./frontend
yarn install
yarn run start:sandbox
```
## Running end-to-end tests
We have a set of Cypress tests that run on the build before a PR can be merged
so it's important that you check these yourself before submitting a PR.
On the server the tests will run against the deployed Heroku app so this is what you probably want to test against:
```
yarn run start:sandbox
```
In a different shell, you can run the tests themselves:
```
yarn run e2e:heroku
```
If you need to test against patches against a local server instance,
you'll need to run that, and then run the end to end tests using:
```
yarn run e2e
```
You may also need to test that a feature works against the enterprise version of unleash.
Assuming the Heroku instance is still running, this can be done by:
```
yarn run start:enterprise
yarn run e2e
```
## Generating the OpenAPI client
The frontend uses an OpenAPI client generated from the backend's OpenAPI spec.
Whenever there are changes to the backend API, the client should be regenerated:
For now we only use generated types (src/openapi/models).
We will use methods (src/openapi/apis) for new features soon.
```
yarn gen:api
rm -rf src/openapi/apis
```
clean up `src/openapi/index.ts` imports, only keep first line `export * from './models';`
This script assumes that you have a running instance of the enterprise backend at `http://localhost:4242`.
The new OpenAPI client will be generated from the runtime schema of this instance.
The target URL can be changed by setting the `UNLEASH_OPENAPI_URL` env var.
## Analyzing bundle size
