Should I avoid this ent query?

This is an example from ents docs:

export const listTeamInvites = query({
  args: { teamId: v.id("teams") },
  async handler(ctx, { teamId }) {
    return await ctx
      .table("teams")
      .getX(teamId)
      .edge("invites")
      .map(async (invite) => ({
        _id: invite._id,
        email: invite.email,
        role: (await invite.edge("role")).name,
      })); // `{ _id: Id<"invites">, email: string, role: string }[]`
  },
});

export const listTeamInvites = query({
  args: { teamId: v.id("teams") },
  async handler(ctx, { teamId }) {
    return await ctx
      .table("teams")
      .getX(teamId)
      .edge("invites")
      .map(async (invite) => ({
        _id: invite._id,
        email: invite.email,
        role: (await invite.edge("role")).name,
      })); // `{ _id: Id<"invites">, email: string, role: string }[]`
  },
});

It's likely there are just a few roles so I guess it's fine but let's say there are many roles or let's say it's ever growing collection i.e "posts". Should I try to avoid this kind of query and doing i.e title: (await invite.edge("posts")).title My example might be silly with "posts" but just want to make a point and to understand if this is ok for larger collections then just "roles".

How to properly update many to many records with ents?

Do I need to update (add or remove) on both sides or one is enough for convex to figure out? I.e:

       await payLink.patch({
          customers: { add: [customer._id] },
        });
        await customer.patch({
          payLinks: { add: [payLink._id] },
        });

       await payLink.patch({
          customers: { add: [customer._id] },
        });
        await customer.patch({
          payLinks: { add: [payLink._id] },
        });

Ents is in maintenance mode. Should I use it?

"Ents is in maintenance mode. We're open to taking PRs, and will make sure it doesn't break. There will not be active feature development from the Convex team." Is it OK to use ents? Should I avoid using it if I started a new project?

Is runMutation transactional?

        await ctx.runMutation(internal.foo.create, {
          foo: "xyz"
        });
        await ctx.runMutation(internal.bar.create, {
          bar: "zyx"
        });

        await ctx.runMutation(internal.foo.create, {
          foo: "xyz"
        });
        await ctx.runMutation(internal.bar.create, {
          bar: "zyx"
        });

will internal.bar.create be executed if internal.foo.create fails?

Whats the best practice/approach for saving and fetching convex images?

- Should I save storageId inside i.e product's table i.e thumbnail: v.id("_stareage") or should I have a separate table i.e productThumbnails? - If I have multiple images (previous question also applies) i.e images: v.array(v.id("_stareage")) when I delete I need to make sure I delete in both places (storage and in database) right? - Should I prefetch images in convex server side when I call i.e getProducts? i.e

return [...products, {...product, images: imageUrlsFromStorage} ]

return [...products, {...product, images: imageUrlsFromStorage} ]

Or should I fetch images client side where I have only storageId id?

Is this is valid Access-Control-Allow-Origin?

This is my http endpoint return:

    return new Response(null, {
      status: 200,
      headers: new Headers({
        "Access-Control-Allow-Origin": "*.xyz.com",
      }),
    });

    return new Response(null, {
      status: 200,
      headers: new Headers({
        "Access-Control-Allow-Origin": "*.xyz.com",
      }),
    });

Would this be valid? "Access-Control-Allow-Origin": "*.xyz.com" ? If not, is there a workaround? Sorry, too lazy to test myself.

how do I efficiently aggregate data?

How do I aggregate data? I.e I have orders, how do I calculate the total amount through entire period? I would assume querying all records and adding up the count wouldn't be the best option?

Is this is legit way to upload files? Haven't seen this in any example

With this approach you do not have to create http route. frontend:

function convertFileToBase64(file: File): Promise<string> {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.onloadend = () => resolve(reader.result as string);
    reader.onerror = reject;
    reader.readAsDataURL(file);
  });
}

  const upload = useAction(api.image.upload);

  const handleUploadLogo = async (file: File | null) => {
    if (!file) return;
    const base64 = await convertFileToBase64(file);
    await upload({ base64, table: "accounts", column: "logo" });
  };

function convertFileToBase64(file: File): Promise<string> {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.onloadend = () => resolve(reader.result as string);
    reader.onerror = reject;
    reader.readAsDataURL(file);
  });
}

  const upload = useAction(api.image.upload);

  const handleUploadLogo = async (file: File | null) => {
    if (!file) return;
    const base64 = await convertFileToBase64(file);
    await upload({ base64, table: "accounts", column: "logo" });
  };

How do I extend convex auth with my custom auth provider?

So idea is to pass 3 things from frontend

singIn("my-custom-provider", {address, message, signature})

singIn("my-custom-provider", {address, message, signature})

and this is where I'm stuck at:

export const { auth, signIn, signOut, store } = convexAuth({
  providers: [
    GitHub,
    ConvexCredentials({
      id: "my-custom-provider"
      authorize: async (credentials, ctx) => {
        const { address, message, signature } = credentials

        const evmAddress = ethers.verifyMessage(message, signature);
        const isVerified = evmAddress === address;

        // ???
      },
    }),
  ],
});

export const { auth, signIn, signOut, store } = convexAuth({
  providers: [
    GitHub,
    ConvexCredentials({
      id: "my-custom-provider"
      authorize: async (credentials, ctx) => {
        const { address, message, signature } = credentials

        const evmAddress = ethers.verifyMessage(message, signature);
        const isVerified = evmAddress === address;

        // ???
      },
    }),
  ],
});

How do I finish this implementation? Should I use ConvexCredentials or should I use something else?

Am I doing this ent query correctly?

export const get = authQuery({
  args: {
    orderId: v.id("orders"),
  },
  handler: async (ctx, args) => {
    if (!ctx.user?.currentAccountId) return null;
    const order = await ctx
      .table("accounts")
      .getX(ctx.user.currentAccountId)
      .edgeX("orders")
      .filter((q) => q.eq(q.field("_id"), args.orderId))
      .firstX();
    return order;
  },
});

export const get = authQuery({
  args: {
    orderId: v.id("orders"),
  },
  handler: async (ctx, args) => {
    if (!ctx.user?.currentAccountId) return null;
    const order = await ctx
      .table("accounts")
      .getX(ctx.user.currentAccountId)
      .edgeX("orders")
      .filter((q) => q.eq(q.field("_id"), args.orderId))
      .firstX();
    return order;
  },
});

I want to get order by id but that order must belong to the account that is ctx.user.currentAccountId

What's the best way to manage long running functions in convex actions?

I have 3 async functions that depend one on each other so I can not do Promise.all I'm running these in internal action ("use node") each function can take ~5 seconds so total action execution time could take ~15 seconds Is this is healthy for convex? is there a better way todo this?

Why sometime ents one-to-one with optional: true work, sometimes not?

so my schema is this:

    wallets: defineEnt({
      privateKey: v.string(),
    })
      .edge("balance", { optional: true })
      .edge("user")
      .edge("store"),

    balances: defineEnt({
      balance: v.any() as BalanceMap,
    })
      .edge("wallet")
      .edge("store")
      .edge("user"),

    wallets: defineEnt({
      privateKey: v.string(),
    })
      .edge("balance", { optional: true })
      .edge("user")
      .edge("store"),

    balances: defineEnt({
      balance: v.any() as BalanceMap,
    })
      .edge("wallet")
      .edge("store")
      .edge("user"),

I first create wallet then I create balance

    // create wallet
    const walletId = await ctx.db.insert("wallets", {
      privateKey: wallet.privateKey,
      userId: ctx.userId,
      storeId,
    });

    // create balance
    const balanceId = await ctx.db.insert("balances", {
      walletId,
      balance: initialBalance,
      userId: ctx.userId,
      storeId,
    });

    // connect balance to the wallet
    await ctx.db.patch(walletId, { balanceId }); 

// ❌ this is where ts and console is not happy. no balanceId field on wallet table, but walletId field on balance seem to be fine

    // create wallet
    const walletId = await ctx.db.insert("wallets", {
      privateKey: wallet.privateKey,
      userId: ctx.userId,
      storeId,
    });

    // create balance
    const balanceId = await ctx.db.insert("balances", {
      walletId,
      balance: initialBalance,
      userId: ctx.userId,
      storeId,
    });

    // connect balance to the wallet
    await ctx.db.patch(walletId, { balanceId }); 

// ❌ this is where ts and console is not happy. no balanceId field on wallet table, but walletId field on balance seem to be fine

In other cases I also use this approach with optional: true and it seem to work fine
