### Start project in dev mode

#### In Docker mode (easy-mode):

On Linux systems:

```bash
git clone git@github.com:datalens-tech/datalens.git
cd datalens
./init.sh --ipv6 --docker-ipv6 --dev-light --dev-root --dev-ui
```

On macOS systems:

```bash
git clone git@github.com:datalens-tech/datalens.git
cd datalens
./init.sh --dev-light --dev-ui
```

#### Local mode:

Install Node.js >= v18.17.0 manually or via [node version manager](https://github.com/nvm-sh/nvm).

Start project in dev mode:

```bash
# Start backend for datalens:
git clone git@github.com:datalens-tech/datalens.git
cd datalens
docker compose -f docker-compose.dev.yaml up

# Start datalens ui in dev mode:
git clone git@github.com:datalens-tech/datalens-ui.git
cd ui
pnpm install --frozen-lockfile
pnpm run dev
```
