## Setting up your development environment
This guide will help you set up your development environment to start contributing to homarr.
## Set up your development environment
### Prerequisites
- **Node.js (lts)**: You can download it from the [official website](https://nodejs.org/).
- **pnpm (latest)**: You can install it by running `npm install -g pnpm`.
- **Git**: You can download it from the [official website](https://git-scm.com/).
- **Docker or Docker Desktop**: You can download it from the [official website](https://www.docker.com/).
- **A GitHub account**: You can create one on the [official website](https://github.com/).
- Node.js 24.18 or newer
- Corepack and pnpm 11.11
- Git
- Docker with Docker Compose
### Setting up the project
The versions in the root `package.json` are the supported baseline. Let Corepack select the repository version instead
of installing an unrelated global pnpm:
1. Fork the repository by clicking on the "Fork" button on the top right corner of the repository page.
```sh
corepack enable
corepack install
pnpm install --frozen-lockfile
```
![Fork button](./img/fork.png)
### Run the Homarr application
2. Clone the repository to your local machine with `git clone`. You can find the url to use by clicking on the "Code" button on the top right corner of your forks repository page.
1. Copy `.env.example` to `.env`.
2. Set `DB_URL` to an absolute writable SQLite file path.
3. Keep Redis and the optional local databases running in one terminal.
4. Apply migrations and start Next.js in another terminal.
![Clone button](./img/clone.png)
```sh
cp .env.example .env
```
3. Change directory to the project folder with `cd homarr`.
Terminal 1:
4. Install the dependencies with `pnpm install`.
```sh
pnpm docker:dev
```
5. Start redis by running `pnpm run docker:dev`. This will run a docker-compose file with a redis service.
Terminal 2:
6. Copy the `.env.example` file to `.env` and replace `DB_URL` with the full path you want to use for the sqlite database file. For example `DB_URL='C:\\Dev\\homarr\\packages\\db\\db.sqlite'`
```sh
pnpm db:migration:sqlite:run
pnpm dev
```
7. Run the migrations to create the sqlite db file with `pnpm run db:migration:sqlite:run`.
The infrastructure command remains in the foreground. Open `http://127.0.0.1:3000`; the first user created through
Homarr becomes the instance administrator.
8. Start the development server with `pnpm dev` and wait for a message that says `✓ Ready in 10.7s`
### Run PocketBase and documentation
9. Open your browser and navigate to [http://localhost:3000](http://localhost:3000). (Loading the page might take up to 2 minutes the first time)
Start PocketBase in another terminal:
### Useful npm scripts
```sh
cp apps/workshop/.env.example apps/workshop/.env
docker compose --env-file apps/workshop/.env -f apps/workshop/docker-compose.yml up --build workshop
```
#### During development
Then start Docusaurus in a third terminal:
- `pnpm dev`: Start the development server.
- `pnpm cli`: Run cli commands.
- `pnpm db:migration:sqlite:run`: Run the migrations to create or update the sqlite db file.
- `pnpm db:migration:sqlite:generate`: Generate a new migration file for the sqlite db. Also works with `mysql`.
- `pnpm db:studio`: Open a visual studio for the database.
- `pnpm package:new`: Create a new package in the monorepo.
```sh
WORKSHOP_API_URL=http://127.0.0.1:8090 pnpm dev:docs
```
#### Checking code quality
PocketBase runs on port 8090 and Docusaurus on port 3003. Stopping the services preserves the PocketBase volume.
- `pnpm lint`: Run the linter to check for code quality issues.
- `pnpm format:fix`: Run the formatter to fix code style issues.
- `pnpm test`: Run the tests. You can also use `pnpm test:ui` to get a UI for the tests.
- `pnpm typecheck`: Run the typescript type checker.
Open `http://127.0.0.1:8090/_/` and create the first PocketBase superuser. The Workshop UI is available at
`http://127.0.0.1:3003/workshop`.
#### Building the project
Point Homarr at the local services with:
- `pnpm build`: Build the project for production.
- `docker build -t homarr .`: Build a docker image for the project.
- `docker run -p 7575:7575 -e SECRET_ENCRYPTION_KEY='your_64_character_hex_string' homarr:latest`: Run the created docker image.
```dotenv
HOMARR_WEBSITE_URL=http://127.0.0.1:3003
WORKSHOP_API_URL=http://127.0.0.1:8090
WORKSHOP_WEB_URL=http://127.0.0.1:3003/workshop
```
Restart `pnpm dev` after changing `.env`. GitHub OAuth is optional locally. See
[`apps/workshop/README.md`](https://github.com/homarr-labs/homarr/blob/HEAD/apps/workshop/README.md) for OAuth,
Workshop moderator promotion, logs, tests, backup, restore, stopping, and intentional volume reset.
### URL testing
Docusaurus reads `HOMARR_WEBSITE_URL` and `WORKSHOP_API_URL` when it starts or builds. Homarr also reads
`WORKSHOP_WEB_URL` when its server starts, so these values do not rely on `NEXT_PUBLIC_*` build variables. Test a
separate API origin before release:
```sh
HOMARR_WEBSITE_URL=http://127.0.0.1:3003 \
WORKSHOP_API_URL=http://127.0.0.1:8090 \
WORKSHOP_WEB_URL=http://127.0.0.1:3003/workshop \
pnpm dev:docs
```
### Useful commands
- `pnpm dev` — Next.js on port 3000.
- `pnpm dev:docs` — Docusaurus only on port 3003.
- `pnpm docker:workshop` — local PocketBase through Docker Compose.
- `pnpm cli` — Homarr operations CLI.
- `pnpm db:migration:sqlite:run` — create or update a SQLite database.
- `pnpm db:studio` — inspect the database.
- `pnpm format` / `pnpm format:fix` — check or apply oxfmt.
- `pnpm lint` / `pnpm lint:fix` — check or apply oxlint.
- `pnpm typecheck` — typecheck all workspaces.
- `pnpm test` — unit and contract suites.
- `pnpm test:workshop` — disposable Workshop integration suite.
- `pnpm build` — production monorepo build.

All public URL variables reject non-HTTP protocols, embedded credentials, query strings, and fragments, and normalize
trailing slashes when Homarr or Docusaurus starts. The Docusaurus-only `WORKSHOP_URL` name is accepted as a deprecated alias for
`WORKSHOP_API_URL` for one release. `WORKSHOP_API_URL` takes precedence.
