Generate .d.ts file

[zeroXBami]

Hi there,

As I understand, from now typechain only generate .ts file instead of .d.ts file, but when I try to import .ts file , I always get error below. And if I want to use .d.ts file? How could I generate that with current newest version ?

error - ./node_modules/.../Router__factory.ts 6:12
Module parse failed: Unexpected token (6:12)
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
| import { Signer, utils, Contract, ContractFactory, Overrides } from "ethers";

I think you're trying to load ts file with a js loader. If you use webpack, by default it will treat files in node_modules as js.

@krzkaczor thank you, let me check, but in case if I want to have .d.ts file? What should I do ?
I m using:
"@typechain/ethers-v5": "9.0.0",
"@typechain/hardhat": "^4.0.0",
"typechain": "7.0.0"

Yes. TC generally (apart from factories...) generates only typings. You need to create runtime object and later cast it to the desired type.

Here are some examples:

• https://github.com/dethcrypto/TypeChain/blob/master/examples/ethers-v4/src/index.ts#L13
• https://github.com/dethcrypto/TypeChain/blob/master/examples/ethers-v5/src/index.ts#L10

Also you might find eth-sdk useful if you're interacting with already deployed, mainnet contracts.
