> Convex supports indexes containing up

Convex supports indexes containing up to 16 fields. You can define 32 indexes on each table. Indexes can't contain duplicate fields.

tried three fields, been battling with typescript for more than an hour gonna continue tomrorow strange, never had issues with convex indexes i wonder if anyone else has succeeded with more than 2 index fields for an index?

What's happening? I have lots of indexes with lots of fields, what error(s) are you seeing? also Tiger how do you not have more than two fields in your indexes, you are not convexing hard enough lol

MapleLeaf 🍁•4mo ago

it's a typescript issue? so it may be a problem with the index definition itself, can you show your schema code?

Tiger 🐅OP•4mo ago

@MapleLeaf 🍁 @erquhart yeah sorry for not being specific its typescript complaining

Function implicitly has return type 'any' because it does not have a return type annotation and is referenced directly or indirectly in one of its return expressions.

guess i gotta convex harder lmfao i tried just focusing on one mutation, commenting the others out trying to narrow this down

export const getFlameProgress = query({
  args: {
    flame: convexFlameUnionSchema,
  },
  handler: async (ctx, args) => {
    const user = await ctx.runQuery(api.users.currentUser)
    if (!user) throw new ConvexError('User not found')

    // return ctx.db
    //   .query('flameProgress')
    //   .withIndex('by_userId_flame_lang', (q) =>
    //     q.eq('userId', user._id).eq('flame', args.flame).eq('lang', user.lang)
    //   )
    //   .unique()
  },
})

export const getFlameProgress = query({
  args: {
    flame: convexFlameUnionSchema,
  },
  handler: async (ctx, args) => {
    const user = await ctx.runQuery(api.users.currentUser)
    if (!user) throw new ConvexError('User not found')

    // return ctx.db
    //   .query('flameProgress')
    //   .withIndex('by_userId_flame_lang', (q) =>
    //     q.eq('userId', user._id).eq('flame', args.flame).eq('lang', user.lang)
    //   )
    //   .unique()
  },
})

when i comment in getting the flame progress user loses its type defintiions as if everything messus up

only thing missing is the morning coffee but lemme get in some water first

erquhart•4mo ago

When you run a function from within another function you have to explicitly type any part of the return value that came from the inner function.

also big cleaned myroom this morning feels so fucking good clean room + good music + write loads of code no way

i see

erquhart•4mo ago

Used to only affect actions but now that any function can run other functions it can happen to any of them

ERQUAHARTTTT ty virtual dap my G thanks so much hahaha

  handler: async (ctx, args) => {
    const user: DataModel['users']['document'] | null = await ctx.runQuery(
      api.users.currentUser
    )

    return ctx.db
      .query('flameProgress')
      .withIndex('by_userId_flame_lang', (q) =>
        q.eq('userId', user._id).eq('flame', args.flame).eq('lang', user.lang)

      )
      .unique()
  },

but then this should work no 🤔 @erquhart still doesnt work 😭 the schema @MapleLeaf 🍁

  flameProgress: defineTable({
    userId: v.id('users'),
    // flame is the difficulty of the world
    flame: convexFlameUnionSchema,
    lang: v.union(v.literal('en'), v.literal('de')),
    isUnlocked: v.boolean(),
    rankCounts: convexRankCountsSchema,
    totalWorldsCount: v.number(),
  }).index('by_userId_flame_lang', ['userId', 'flame', 'lang']),

  flameProgress: defineTable({
    userId: v.id('users'),
    // flame is the difficulty of the world
    flame: convexFlameUnionSchema,
    lang: v.union(v.literal('en'), v.literal('de')),
    isUnlocked: v.boolean(),
    rankCounts: convexRankCountsSchema,
    totalWorldsCount: v.number(),
  }).index('by_userId_flame_lang', ['userId', 'flame', 'lang']),

full current query

  },
})

MapleLeaf 🍁•4mo ago

what's convexFlameUnionSchema?

erquhart•4mo ago

That’s still leaning on inference

MapleLeaf 🍁•4mo ago

that seems potentially relevant oh wait oh no yeah i see what erquhart means lol

Tiger 🐅OP•4mo ago

what am i missing

MapleLeaf 🍁•4mo ago

const user: DataModel['users']['document'] | null that's the issue

Tiger 🐅OP•4mo ago

shouldnt that be ok

MapleLeaf 🍁•4mo ago

does it work if you remove it? but also why is that there

Tiger 🐅OP•4mo ago

type annotation to work around the inference issue

MapleLeaf 🍁•4mo ago

oh :ded: maybe put an annotation on the currentUser query instead? the return type probably

erquhart•4mo ago

I can’t remember if this works but try typing that return value as Doc<‘flameProgress’>

MapleLeaf 🍁•4mo ago

issues like this are kind of just a guess lol

erquhart•4mo ago

Might still be in the inference loop

      )
      .unique()
  },
})

this gets the job done cheers love you all gonna add a code comment here so my future self doesn't get all confused

MapleLeaf 🍁•4mo ago

fair enough

Tiger 🐅OP•4mo ago

when ure evil enough to think

MapleLeaf 🍁•4mo ago

fwiw this might be why I tend to prefer having functions (like getCurrentUser(ctx)) to reuse functionality

Tiger 🐅OP•4mo ago

its time for me to writer a post why not to use convex

MapleLeaf 🍁•4mo ago

i mean hey if it has valid criticisms, the convex team would still appreciate it 😛

Tiger 🐅OP•4mo ago

yeah, but i guess this is some quriky ts issue 😭 thats better actually when i think about it hmmh much cleaner love it
