The declaration file could not be located even after the .d.ts file was successfully generated

I encountered an issue while working with TypeScript

src/usecases/Reports/GenerateReportUseCase.ts(7,23): error TS7016: Could not find a declaration file for module 'convert-json-to-csv'.

This package lacks typings, which results in an error when running 

npm i --save-dev @types/convert-json-to-csv

My folder structure is as follows:

https://i.sstatic.net/wUbH1.png

Within index.d.ts, I have added the following declaration:

declare module 'convert-json-to-csv';

In my tsconfig file, I included this line:

"typeRoots": ["./src/types"],

What could be causing this issue?

Answer №1

I encountered a problem with my server as it was utilizing ts-node instead of tsc. To ensure that the module declarations were properly recognized, I found it necessary to modify my start script as shown below: 

"start": "nodemon --legacy-watch --files"

It is important to highlight the inclusion of --files, which proved to be the solution to this issue.
