# Dify Frontend

This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).

## Getting Started

### Run by source code

To start the web frontend service, you will need [Node.js v18.x (LTS)](https://nodejs.org/en) and [pnpm version 9.12.2](https://pnpm.io).

First, install the dependencies:

```bash
pnpm install
```

Then, configure the environment variables. Create a file named `.env.local` in the current directory and copy the contents from `.env.example`. Modify the values of these environment variables according to your requirements:

```bash
cp .env.example .env.local
```

```
# For production release, change this to PRODUCTION
NEXT_PUBLIC_DEPLOY_ENV=DEVELOPMENT
# The deployment edition, SELF_HOSTED
NEXT_PUBLIC_EDITION=SELF_HOSTED
# The base URL of console application, refers to the Console base URL of WEB service if console domain is
# different from api or web app domain.
# example: http://cloud.dify.ai/console/api
NEXT_PUBLIC_API_PREFIX=http://localhost:5001/console/api
# The URL for Web APP, refers to the Web App base URL of WEB service if web app domain is different from
# console or api domain.
# example: http://udify.app/api
NEXT_PUBLIC_PUBLIC_API_PREFIX=http://localhost:5001/api

# SENTRY
NEXT_PUBLIC_SENTRY_DSN=
```

Finally, run the development server:

```bash
pnpm run dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the file under folder `app`. The page auto-updates as you edit the file.

## Deploy

### Deploy on server

First, build the app for production:

```bash
pnpm run build
```

Then, start the server:

```bash
pnpm run start
```

If you want to customize the host and port:

```bash
pnpm run start --port=3001 --host=0.0.0.0
```

## Storybook

This project uses [Storybook](https://storybook.js.org/) for UI component development.

To start the storybook server, run:

```bash
pnpm storybook
```

Open [http://localhost:6006](http://localhost:6006) with your browser to see the result.

## Lint Code

If your IDE is VSCode, rename `web/.vscode/settings.example.json` to `web/.vscode/settings.json` for lint code setting.

## Test

We start to use [Jest](https://jestjs.io/) and [React Testing Library](https://testing-library.com/docs/react-testing-library/intro/) for Unit Testing.

You can create a test file with a suffix of `.spec` beside the file that to be tested. For example, if you want to test a file named `util.ts`. The test file name should be `util.spec.ts`.

Run test:

```bash
pnpm run test
```

If you are not familiar with writing tests, here is some code to refer to:
* [classnames.spec.ts](./utils/classnames.spec.ts)
* [index.spec.tsx](./app/components/base/button/index.spec.tsx)
