Fix the Cannot Find Name 'require' Error in TypeScript

To fix the "cannot find name 'require'" error in TypeScript, install the @types/node package into your project by running npm i -D @types/node.

This error can occur when you try to use the Node.js require() function in a TypeScript file.

You can fix it by running the following command in a terminal window at the root directory of your project:

npm i -D @types/node

If the error persists, try adding "node" to the types array in your tsconfig.json file:

tsconfig.json

{
  "compilerOptions": {
    "types": [
      // ... other types
      "node"
    ],
  },
}
