24function updateFeedback(ref) {
25  let feedback = [...document.getElementsByTagName('a')].find(e => e.innerText == 'Feedback')

32Finally, you may be wondering why I queue up feedback in `@stevekrouse.docsFeedback`, a private JSON val, and then process it via [`@stevekrouse.formFeedbackAlert`](https://www.val.town/v/stevekrouse.formFeedbackAlert) instead of sending it along to Discord directly in this val. I [tried that originally](https://www.val.town/v/stevekrouse.docFeedbackForm?v=61) but it felt too slow to wait for the API call to Discord before returning the "Thanks for your feedback" message. This is where the `context.waitUntil` method (that Cloudflare workers and Vercel Edge Functions support) would really come in handy – those allow you to return a Response, and then continue to compute. Currently Val Town requires you to stop all compute with the returning of your Response, so the only way to compute afterwards is to queue it up for another val to take over, and that's what I'm doing here.

15There will be one migration per val, per version.
16
17You can do anything you want in the function passed to `migrate`; create or alter tables, populate data... whatever!

19## Migrating backwards

171. [Generate your keypair](https://www.val.town/embed/new?code=import+%7B+set+%7D+from+%22https%3A%2F%2Fesm.town%2Fv%2Fstd%2Fset%22%3B%0Aimport+%7B+generateKeys+%7D+from+%22https%3A%2F%2Fesm.town%2Fv%2Fstevekrouse%2FgenerateKeys%22%3B%0A%0Alet+keys+%3D+await+generateKeys%28%29%0A%0Aexport+let+exportedKeySetter+%3D+Promise.all%28%5B%0A++set%28%22exportedKeys%22%2C+keys%29%2C%0A++set%28%22publicKey%22%2C+keys.publicKey%29%0A%5D%29)
182. On [your publicKey](https://www.val.town/v/me/publicKey) click the lock icon🔒 to change the permissions to `Unlisted`.
193. [Fork this helper function](https://www.val.town/v/stevekrouse.turso/fork) replacing `stevekrouse` with your own username

35## Architecture
36
37This @std.turso function is the client or SDK to @std.tursoAPI, which acts as a "proxy" to Turso. It handles authentication, creates databases, and forwards on your SQL queries. You can get lower latency (~200ms vs ~800ms), more storage, databases, CLI & API access by having your own Turso account.

131. This val requires you to setup public key auth, which is really just three clicks here: https://blog.val.town/public-key-auth-val-town-users-can-be-your-users
142. [Optional] You can setup a helper function so you don't have to pass your keys every time:
15
16```js
18```
19
20Warning: Do **not** make your blob function public or unlisted. That would allow anyone to use it.
21
22## Usage

18```
19
20⚠️ For the notification to be sent it needs to be published (`publish` function).
21
22## Use helper
23
24Executes specified functions that can modify the notification. Can be used to streamline authentication, apply common operations, etc.
25
26```ts
40```
41
42You can pass it multiple functions.
43
44## Functions
45
46### `toServer(url)` - optional
120```
121
122Alternatively you can use dedicated functions: `.withMinPriority()`, `.withLowPriority()`, `.withDefaultPriority()`, `.withHighPriority()`, `.withMaxPriority()`
123
124```ts

22
23```js
24function updateFeedback(ref) {
25  let feedback = [...document.getElementsByTagName('a')].find(e => e.innerText == 'Feedback')
26  feedback.setAttribute('href', "https://stevekrouse-docfeedbackform.web.val.run/?ref=" + ref)
