[ethers-v5] Contract types not exported in generated index.ts

The index.ts only reexports the factory types, it does not export the contract types, the ones at <ContractName>.d.ts. These types should also be exported.

I’m using a private npm package where the TypeChain-generated code with @typechain/ethers-v5 is exposed in that package. I’m using it in a React app (specifically a Next.js app) using TypeScript with a version >4, and I’m getting an error when it hits the export type line when I import from the root of the TypeChain output, or an error at the import type line if I try to import one of the .ts factory files directly where it imports the .d.ts file.

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

I’m seeing if I can get Webpack to ignore the .d.ts files to get around this, but if anyone is aware of another workaround, please let me know. Thanks!

I am stucking the same thing, have you found the answer?

Imagine you want to create a reusable npm package with the code generated by TypeChain, instead of generating it on demand in every project you want to use it.

In that case you want a package.json main key and a typescript types key with everything you typically need in the usage of package, which includes the contract types, so you can just do import { MyContract } from "my_package";.

In the current state you have to do some trickery by copying the .d.ts files over to the tsc destination directory.
