# Squiggle Components
This package contains all the components for squiggle. These can be used either as a library or hosted as a [storybook](https://storybook.js.org/).
# Build for development
We assume that you had run `yarn` at monorepo level, installing dependencies.
You need to _prepare_ by building and bundling `squiggle-lang`
``` sh
We assume that you had run `yarn` at monorepo level, installing dependencies.
You need to _prepare_ by building and bundling `squiggle-lang`
```sh
cd ../squiggle-lang
yarn build
```
If you've otherwise done this recently you can skip those.
Run a development server
``` sh
```sh
yarn start
```
And build artefacts for production,
``` sh
```sh
yarn bundle # builds components library
yarn build # builds storybook app
```

# Squiggle Playground
This repository contains the squiggle playground, a small web interface
for playing around with squiggle concepts.
It depends on `@quri/squiggle-components` and `@quri/squiggle-lang` so both of them will
need to be packaged for this to work. This can be done from the root directory
with
```
yarn build:lang
yarn build:components
```
Then, starting the playground can be done with:
```
yarn parcel
```
