## Development
|
||||||
|
### Requirements
|
||||||
|
* [npm](https://www.npmjs.com/)
|
||||||
|
|
||||||
|
### Setting up
|
||||||
|
```shell script
|
||||||
|
# Install dependencies (only needed once)
|
||||||
|
$> npm ci
|
||||||
|
```
|
||||||
|
|
||||||
|
### Building
|
||||||
|
```shell script
|
||||||
|
# Build the tool in `dist/` for development
|
||||||
|
$> npm run dev
|
||||||
|
# Same as above, but automatically rerun it whenever files are changed
|
||||||
|
$> npm run dev:server
|
||||||
|
# Build the tool in `dist/` for deployment
|
||||||
|
$> npm run deploy
