Reproducing TypeScript Compilation Error with viem

This guide will walk you through the steps to reproduce the TypeScript compilation error when using the viem library.

Prerequisites

Before starting, ensure that you have Node.js and npm installed on your system.

Steps

1. Create a new directory and navigate into it:

   mkdir VIEM_TEST
   cd VIEM_TEST

2. Initialize a new npm project:

   npm init -y

3. Install the viem library:

   npm install viem@2.7.11

4. Create a TypeScript file named index.ts with the following content:

   // index.ts
   import { createPublicClient } from "viem/_types/clients/createPublicClient";
   import { createWalletClient } from "viem/_types/clients/createWalletClient";
   
   
   function greet(name: string): string {
       console.log( createPublicClient);
       console.log(  createWalletClient);
       
       return `Hello, ${name}!`;
       
   }
   
   const personName: string = "John";
   console.log(greet(personName));

5. Create a tsconfig.json file with the following configuration:

   {
       "compilerOptions": {
           "forceConsistentCasingInFileNames": true,
           "newLine": "lf",
           "noFallthroughCasesInSwitch": true,
           "noImplicitReturns": true,
           "noUncheckedIndexedAccess": true,
           "noUnusedParameters": true,
           "strict": true,
           "target": "ES2019",
           "moduleResolution": "node",
           "esModuleInterop": true
       },
       "include": [
           "src/**/*.ts"
       ]
   }
   

6. Run the TypeScript compiler:
