Can't |start %canvas

[johnhyde]

I did the following:

• dojo> |merge %base %canvas
• dojo> |mount %canvas
  (in pier)
• $ rm -r canvas/*
  (in /ui)
• $ npm i
• $ npm run build
• $ ../install.sh ~/urbit/zod/canvas
• created a sys.kelvin file with [%zuse 419]
• dojo> |commit %canvas
  and that all worked fine.
  But when I try: dojo> |start %canvas, I get

clay: %a no file at path [%base 1 /app/canvas/hoon]
crud: %belt event failed

Are you on master? I have a branch (that's the one deployed on my moon) that is set up for software distribution:

https://github.com/yosoyubik/canvas/tree/distro

Your instructions should work for getting the backend running. Then you can go to http://localhost:8080/~debug and log in—you need a cookie for developing the UI.

Then go to /ui and npm i && npm run dev.

This is going to serve the frontend on http://localhost:3000/app/canvas—it's proxying all the calls to the backend to port 8080 on your urbit.

I think that's all you need to get it to work, let me know if run into any problems and thanks for trying it out! :)

When I try checking out distro and committing that to my desk, I get:

and I have no idea what to make of that.

If I stick with master, running npm run dev and visiting http://localhost:3000/apps/canvas gives me,

which is something, I guess. Should I assume that I need to get the distro branch working to develop on the ui?

Edit: If I actually use the right url 🤦‍♂️, I get a better situation, although there's still an error:

TypeError: Cannot read property 'default' of null
    at eval (/src/components/Header.svelte:38:61)

Edit #2: Actually, after deleting desk.docket-0, I can commit the desk from distro, but I still get the 404 error on the frontend, even at the correct URL.

[yosoyubik]

It looks like the docket-0 mark is missing—the repo here has only the files that relate to canvas, but no the whole thing, which is something I should probably fix before I merge to master. In the distro guide you have the steps for getting a minimal desk with the necessary files prior to putting all the canvas files (the part about ./symbolic-merge.sh will set everything up)

https://urbit.org/docs/userspace/dist/guide#create-desk

[johnhyde]

Sounds like Urbit needs a package dev-desk management system.
Once I figured out I needed to run |install our %canvas, things improved dramatically. I'll include it in my README updates.
