How to retrieve and receive Bigint data to/from TRPC procedure

Node: v16.15.1 I'm trying to return an object which contains an amount property from one of my TRPC procedures... This property should retrieve a bigint. Unfortunately, I'm receiving error: TypeError: Do not know how to serialize a BigInt When doing this. I've already configured superjson Data transformer in my TRPC server instance creation and in client's createTRPCNext's response, but this didn't solve the problem. What is the most appropriate way of receiving and returning bigint properties to/from my TRPC procedures inside my Next.js application? I appreciate any help, thanks! ๐Ÿ™๐Ÿผ These are my packages versions: "@trpc/client": "10.14.1", "@trpc/next": "10.14.1", "@trpc/react-query": "10.14.1", "@trpc/server": "10.14.1", "next": "13.2.3", "superjson": "1.12.3"

You probably just need to register the type with superjson Itโ€™s in their docs how to do this

Hey @Nick Lucas ! I appreciate your quick response, I'll take a look on this now and let you know in what it results ๐Ÿ˜‰

@Nick Lucas Adding the following code wasn't enough for getting rid of the error: TypeError: Do not know how to serialize a BigInt registerCustom<bigint, string>( { isApplicable: (v): v is bigint => typeof v === "bigint", serialize: (v) => v.toString(), deserialize: (v) => BigInt(v), }, "bigint", ); Do you have any other suggestion on how to fix this issue? I'm send attached to this message my TRPC server file + TRPC client file so you can have more visibility of how I'm implementing things here ๐Ÿ‘

Youโ€™ll need to add it on both client and api if you havenโ€™t, otherwise Iโ€™d check their GitHub issues

I've extracted the registration of this custom type to a file which is being imported in both client and server TRPC configuration files, but the error below persists: TypeError: Do not know how to serialize a BigInt I wonder if this is related to TRPC procedures config, to SuperJson lib (which should give support to BigInt without the need of registering new custom serialize/deserialize function for it, as mentioned in their docs: https://github.com/blitz-js/superjson#examples-3) or to Next.js Neither SuperJson, TRPC nor Next.js Github issues contain related issues, so I'm finding myself completely stuck in this limitation now ๐Ÿ˜ฎโ€๐Ÿ’จ

The workaround is to extend BigInt by modifying the prototype Create a bigintPatch.ts file and paste this code
//@ts-expect-error
BigInt.prototype.toJSON = function () {
const int = Number.parseInt(this.toString())
return int ?? this.toString()
}
//@ts-expect-error
BigInt.prototype.toJSON = function () {
const int = Number.parseInt(this.toString())
return int ?? this.toString()
}
then import it like import "bigintPatch.ts" on the page where youโ€™re calling the query/mutation

Hi @NEO I've added something very similar (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt#use_within_json) to the code snippet you've shared and the issue was fixed! ๐Ÿฅณ Thanks so much for your help @nlucas and @NEO, I really appreciate it! trpc

BigInt values represent numeric values which are too large to be represented by the number primitive.
