I'm trying to add typescript to a existing react project but I'm getting an error when re-starting the server with npm start.
I'm following the steps from this documentation but I'm getting an error message:
The only thing I might not have right is the react.scripts versions. Here is a copy of the results thrown by npm outdated:
Also, I checked my dependencies and everything seems to be normal.
Things I have done:
- run npm update to update all react related packages
- I have deleted the node files and re install them with npm install
- I have renamed other files to .tsx including the index.js file but I get another error:
Really keen to move this project to the next level with typescript but I have been stack trying to get it to work. By the way, here are my dependencies too:

Lastly, I found this answer but not sure what they mean. Anyone keen to explain maybe Could not find a required file. - Adding TypeScript to React project
./src/containers/ItemsHolder/ItemsHolder.jsand it does not find it because you have renamed it to .tsx
