- Export Canvas Images as SVG.

- Allows creation of Public/Private Canvas.
- Others can join a Public Canvas and work collaboratively in a cool art project.

## Access

Search for `~dister-norsyr-torryn` in Grid to find the Canvas app, and install it from there

A public canvas is hosted at

```hoon
~picsel-norsyr-torryn/public
```

## Development Setup

1. Clone the repo, of course
2. Create a new desk in Urbit to install canvas in
- `$ ./urbit -F zod` - Spin up a fake zod, if you haven't already (should be running on port 8080. If not, you'll need to edit [`ui/svelte.config.js`](ui/svelte.config.js))
- `dojo> +code` - Get an access code and use it to sign in to your ship at http://localhost:8080
- `dojo> |mount %base` - Mount `%base`, if you haven't already
- `dojo> |merge %canvas our %base` - Create a `%canvas` desk
- `dojo> |mount %canvas` - Mount the desk so it appears in your pier
- `$ rm -r zod/canvas/*` - Clear out your new desk to make room for the actual desk
- Follow the instructions [here](https://urbit.org/docs/userspace/dist/guide#create-desk) to merge the `base-dev` and `garden-dev` desks into your desk
3. Copy canvas desk to Urbit
From the repo folder, run `./install.sh ` where `` might be something like `~/urbit/zod/canvas`
You can alse run `./install.sh -w ` if you want to watch for changes.
4. Install `%canvas` in Dojo with
- `dojo> |commit %canvas` (do this after every change to see it reflected in Urbit)
- `dojo> |install our %canvas`(only necessary the first time, I think)
5. Serve the UI for development
In the repo folder:
- `cd ui`
- `npm i` (short for `npm install`)
- `npm run dev` (runs on port 3000. To run on a different port: `npm run dev -- --port 3001`)
- Visit http://localhost:3000/apps/canvas
6. Eventually, build the UI to test in Urbit for real test
- `npm run build` (in `/ui`)
- `./install.sh ` (in project root)
- `|commit %canvas` (in dojo)
