Kysely SqlCommnenter
SqlCommenter plugin for Kysely
Getting started
npm install kysely-sqlcommenter
SqlCommenterPlugin does not change the API of Kysely. You can only provide it callback for getting the metadata for the comment. AsyncLocalStorage or any alternative is needed.
Initialize the AsyncLocalStorage
:
import { AsyncLocalStorage } from 'node:async_hooks'
import { SqlCommentLike } from 'kysely-sqlcommenter'
const asyncLocalStorage = new AsyncLocalStorage<SqlCommentLike>()
Register the SqlCommenterPlugin
using the asyncLocalStorage
in callback:
import { SqlCommenterPlugin } from 'kysely-sqlcommenter'
const db = new Kysely<DB>({
// ... kysely config
plugins: [
// Provide callback
new SqlCommenterPlugin(() => asyncLocalStorage.getStore()),
],
})
Create a root middleware, register the root span with storage via asyncLocalStorage.run
. Everything in the callstack of this next
will have access to a shared copy of the storage (new calls will have exclusive storage). You can initialize it with a value.
app.use((req, res, next) => {
asyncLocalStorage.run({ controller: req.path }, next)
})
Any kysely calls will have the appropriate SqlComment
db.selectFrom('cats').select(['id', 'name'])
// select "id", "name" from "cats" /*controller='cats'*/
See the full working example for express here, including concurrency demo and adjusting the comment in other middleware.
