Make Vercel URL rewrites precise (#2913)
### The problem

Right now we use a catchall path in Vercel routing config to rewrite all
requests that don't match existing assets to `/index.html`, which is
needed for client side routing to work. This, however, messes up 404
errors for truly non-existing files which won't be handled by the SPA,
because they get redirected to index.html.

Even worse, this interacts very poorly with caching. Normally if we
request a non-existent file, then put the file in place, and request the
file again, we'll get 404 the first time and the actual file the second
time. However, in our case we instead return `/index.html` after the
first attempt and cache that response, making it impossible to correct a
missing file without cache flush.

### The solution

One way to fix this is to make the regex in Vercel config precise, so
that they only match our SPA routes. However, it can be dangerous,
because this means we'll need to manually update the config with new SPA
routes every time we add any. This PR tests that regexes we're using in
Vercel match all routes that we set in the SPA router.

### Potential future improvements

It's very possible to generate Vercel's config from React Router routing
objects, but at the moment it's not done because that would require
importing most of dotcom during the build phase, which seem to cause
errors.

### Change Type

- [x] `internal` — Any other changes that don't affect the published
package[^2]

### Test Plan

1. Might need a light smoke test after deployment to dotcom.

- [x] End to end tests

Project overview

This project is a Next.js application which contains the tldraw free as well as the tldraw pro applications. We are currently using the Next.js 13 option of having both pages (tldraw free) and app (tldraw pro) directory inside the same app. We did this since the free offering is the continuation of a Next.js version 12 app and it allowed us to combine it with the new App router option from Next.js 13 for tldraw pro without having to do a full migration to App router.

We also split the supabase into two projects:

  • tldraw-v2 for tldraw free where we mainly store the snapshots data
  • tldraw-pro for tldraw pro which holds all the relational data that the pro version requires

On top of that we also use R2 for storing the documents data.

How to run the project

Tldraw pro

The development of tldraw pro happens against a local supabase instance. To set that up, you'll first need to install & start docker.

Once docker is started & you've run yarn to install tldraw's dependencies, the rest should be handled automatically. Running yarn dev-app will:

  1. Start a local instance of supabase
  2. Run any database migrations
  3. Update your .env.local file with credentials for your local supabase instance
  4. Start tldraw

The supabase local development docs are a good reference. When working on tldraw, the supabase command is available by running yarn supabase in the apps/app directory e.g. yarn supabase status.

When you're finished, we don't stop supabase because it takes a while each time we start and stop it. Run yarn supabase stop to stop it manually.

If you write any new database migrations, you can apply those with yarn supabase migration up.

Some helpers

  1. You can see your db schema at the Studio URL printed out in the step 2.
  2. If you ever need to reset your local supabase instance you can run supabase db reset in the root of apps/app project.
  3. The production version of Supabase sends out emails for certain events (email confirmation link, password reset link, etc). In local development you can find these emails at the Inbucket URL printed out in the step 2.

Tldraw free

The development of tldraw free happens against the production supabase instance. We only store snapshots data to one of the three tables, depending on the environment. The tables are:

  • snapshots - for production
  • snapshots_staging - for staging
  • snapshots_dev - for development

For local development you need to add the following env variables to .env.local:

  • SUPABASE_URL - use the production supabase url
  • SUPABASE_KEY - use the production supabase anon key

Once you have the environment variables set up you can run yarn dev-app from the root folder of our repo to start developing.

Running database tests

You need to have a psql client installed. You can then run yarn test-supabase to run db tests.

Sending emails

We are using Resend for sending emails. It allows us to write emails as React components. Emails live in a separate app apps/tl-emails.

Right now we are only using Resend via Supabase, but in the future we will probably also include Resend in our application and send emails directly.

The development workflow is as follows:

1. Creating / updating an email template

To start the development server for email run yarn dev-email from the root folder of our repo. You can then open http://localhost:3333 to see the result. This allows for quick local development of email templates.

Any images you want to use in the email should be uploaded to supabase to the email bucket.

Supabase provides some custom params (like the magic link url) that we can insert into our email, check their website for more info.

2. Generating the html version of the email

Once you are happy with the email template you can run yarn build-email from the root folder of our repo. This will generate the html version of the email and place it in apps/tl-emails/out folder.

3. Updating the template in Supabase

Once you have the html version of the email you can copy it into the Supabase template editor. You can find the templates here.
