# Developing
## Starting the Development Server
Once you've created a project and installed dependencies with `npm install` (or
`pnpm install` or `yarn`), start a development server:
```bash
npm run dev
```
To have the whole stack backing your dev environment, 3 solutions:
### 1. Backend is run by docker
In the root folder:
```bash
docker build . -t windmill
docker-compose up db server
```
### 2. Backend is run by cargo
**Prerequisites**
- Install Rust [as explained on the website](https://www.rust-lang.org/tools/install).
- Install llvm
**on OSX:**
```bash
brew install llvm caddy gsed
# make LLVM tools available on PATH
echo 'export PATH="/opt/homebrew/opt/llvm/bin:$PATH"' >> ~/.zshrc
# now, restart your shell. You should now have the `lld` binary on your PATH.
```
**Do a Frontend Build**
In order to run the backend, you need to have a frontend build inside `frontend/build/`.
Otherwise, `cargo run` will break.
So, in the frontend folder, run:
```bash
# !!! on OSX, you are not allowed to use the system SED, but you need to use GNU SED.
# !!! thus, in `frontend/package.json`, replace all `sed` occurences with `gsed`.
# prerequisite for build
npm run generate-backend-client
npm run build
# now, you'll have a `frontend/build` folder.
```
In the root folder:
```bash
docker-compose up db
```
In the backend folder:
```bash
DATABASE_URL=postgres://postgres:changeme@127.0.0.1:5433/windmill?sslmode=disable cargo run
```
You can now access [http://127.0.0.1:8000](http://127.0.0.1:8000).
### In both cases
In the frontend folder:
```bash
sudo caddy run --config ./Caddyfile
```
(sudo is required to bind port 80 and 443)
and then go to <http://localhost>
### Backend is run by remote!
```bash
sudo caddy run --config ./CaddyfileRemote
```
and then go to <http://localhost>
## Building
```bash
npm run build
```
## Generating the backend client automatically
```bash
npm run generate-backend-client
```
## Formatting
This project uses [prettier](https://prettier.io/docs/en/install.html) and
[prettier-plugin-svelte](https://github.com/sveltejs/prettier-plugin-svelte), be
sure to install them and set up your editor to run prettier automatically before
you commit.
Recommended config for VS Code:
- [Prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode)
for formatting
- [Svelte for VS Code](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode)
for highlighting and Intellisense
- make sure that your VS Code `settings.json` has the following lines:
```json
"[svelte]": {
"editor.defaultFormatter": "esbenp.prettier-vscode"
}
```
- turn _format on save_ on
