What is the process for adding new methods to a predefined data type?

Currently, I am utilizing Webpack's require.context in order to eliminate redundancy while importing multiple pages. However, TypeScript is throwing an error stating that 

Property 'context' does not exist on type 'NodeRequire'.
.

I attempted to address this issue by using declaration merging to include context in NodeRequired, following the guidelines outlined under "Merging Interfaces" in the TS docs. Despite implementing this solution, the error persists.

Below is a snippet of the relevant section of my code:

interface NodeRequire {
  context(path: string): NodeRequire;
}

const pagesCtx = require.context("./pages/"); // The error is triggered here
typescript

Answer №1

After encountering the issue, I managed to resolve it by including 'webpack' and 'webpack-env' in the types array within my tsconfig.json

"types": [
  "node",
  "mocha",
  "chai",
  "webpack",
  "webpack-env"
],
