Question

I have setup new Typescript/React project, getting this error message in the tsconfig.json file

"Cannot find type definition file for 'bson'. The file is in the program because: Entry point for implicit type library 'bson'"

any ideas.

here is my tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": false,
    "forceConsistentCasingInFileNames": true,
    "noEmit": true,
    "esModuleInterop": true,
    "module": "esnext",

    "jsx": "preserve"
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"],
  "exclude": ["node_modules"]
}

Answer 1

sometimes this is an eslint bug, try closing VSCODE and opening it again... It happened to me and I solved it that way.

Answer 2

Found the solution on github

These errors occur when you have subdirectories of a typeRoots directory (in this case node_modules/@types) that do not contain index.d.ts

For me, the problem was because I was creating a library that did exported a bunch of interfaces & types

Here is an example

types-folder
├─── index.d.ts
└─── child-folder
     └─── index.d.ts // <-- Mandatory
