Is it possible to use in chrome extension?

[lionelhorn]

Hello,

I'm trying to make kikko work in a browser extension but without luck so far.

Do you have any pointers or idea if it's compatible? How to make it work?

What I tried so far is to initalize the db from a ServiceWorker / background page.

With wa-sqlite

https://github.com/lionelhorn/kikko-in-browser-extension/blob/7163528b2152e70d94cacb5ef6ea5c014f63b82b/src/background/index.ts#L29-L38

With wa-sqlite, the first error was

Uncaught (in promise) TypeError: Failed to fetch
    at wa-sqlite-async.mjs:93:285
    at wa-sqlite-async.mjs:93:504
    at wa-sqlite-async.mjs:94:9
    at Object.initialize (index.js:2855:34)
    at ee (initDb.ts:142:25)
    at async index.ts:51:16

I managed to apparently fix that one by adding it to the extension manifest.

but then get the following

@kikko-land_wa-sqlite-web-backend.js?v=2af23068:3107 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'apply')

With absurd sql backend.

@lionelhorn it seems to be possible to run it in service worker, regarding jlongster/absurd-sql#54 . It will take a look, hope this week 🙂

@quolpr Thanks for the help.

I dug into it a bit more.

Uncaught (in promise) ReferenceError: Worker is not defined seen in my previous attemps is I think related to the way chrome extension work with their manifest v3 (mv3). Service worker can't spawn new Worker.

So I tried to make it work with a chrome extension using manifest v2.
Repro repo : https://github.com/lionelhorn/sqlite-browser-extension-mv2

For all options, wasm files are properly fetched and loaded.

Using wa-sqlite directly, it seems to work.

https://github.com/lionelhorn/sqlite-browser-extension-mv2/blob/main/src/sqlite-backends/wasqlite-direct.ts
I get no error in the console.

The indexdb appears in application storage but I can't run a dummy migration.

Using wa-sqlite backend from kikko

I get the same error message as previously using in extension with manifest v3.
