Function to release context post-batching?

app.use('/trpc', async (req, res, next) => {
    const client = await getClient()
    req.client = client

    await createExpressMiddleware({
        router: appRouter,
        createContext
    })(req, res, next)

    if (req.client) {
        await req.client.release()
    }
})

app.use('/trpc', async (req, res, next) => {
    const client = await getClient()
    req.client = client

    await createExpressMiddleware({
        router: appRouter,
        createContext
    })(req, res, next)

    if (req.client) {
        await req.client.release()
    }
})

and actually...this can be simplified into just one middleware for /trpc

Function to release context post-batching?

@Alex / KATT 🐱 I think I got this working just with express middleware. Somewhat hacky but...it's working!

app.use(async (req, res, next) => {
    const client = await getClient()
    req.client = client
    next()
})

app.use('/trpc', async (req, res, next) => {
    await createExpressMiddleware({
        router: appRouter,
        createContext,
    })(req, res, next)
    next()
})

app.use(async (req, res) => {
    if (req.client) {
        await req.client.release()
    }
})

app.use(async (req, res, next) => {
    const client = await getClient()
    req.client = client
    next()
})

app.use('/trpc', async (req, res, next) => {
    await createExpressMiddleware({
        router: appRouter,
        createContext,
    })(req, res, next)
    next()
})

app.use(async (req, res) => {
    if (req.client) {
        await req.client.release()
    }
})

Was there a reason for the removal of teardown? I'm happy to suggest reverting but lack the context.

Thanks, I'll peek at that. I'm also going to experiment with moving the db connection logic onto the express middleware layer

Front to back end type inference with parameters sent via request

Just following up with this article, apparently I’ve been fighting against a tRPC limitation this whole time! https://dev.to/zenstack/limitation-of-trpcs-type-inference-and-how-we-improved-it-47fl

This is incredibly helpful thank you and I really appreciate the effort in pointing me in the right direction. This has been such a fun exercise in improving my typescript skills so I greatly prefer guidance like this.

Front to back end type inference with parameters sent via request

Gotcha ok, I’ll look into doing that in the morning, thanks so much! Do you have any guidance on utility types I should be using to build it?

Front to back end type inference with parameters sent via request

I definitely won't discount that I may be going about this the wrong way for what it's worth! But I'm super curious if this is feasible because it would perfect the developer experience here.

Nested with clauses aside, what about parameters like columns that should directly affect the return value?

export const getEntityFetchProcedures = <TTableName extends TableNames>(
    table: TTableName,
) => ({
    discordDemo: privateProcedure
        .input(
            columns =>
                ({ columns } as {
                    columns: NonNullable<FindFirstArg<TTableName>>['columns']
                }),
        )
        .query(async ({ input }) => {
            const queryRef = db.query[table]
            return await queryRef.findFirst(input)
        }),
})

export const getEntityFetchProcedures = <TTableName extends TableNames>(
    table: TTableName,
) => ({
    discordDemo: privateProcedure
        .input(
            columns =>
                ({ columns } as {
                    columns: NonNullable<FindFirstArg<TTableName>>['columns']
                }),
        )
        .query(async ({ input }) => {
            const queryRef = db.query[table]
            return await queryRef.findFirst(input)
        }),
})
