Put an end to the endless game of defining TypeScript between Aurelia CLI and Visual Studio 2017 builds

I am encountering TypeScript errors in my Visual Studio build for an Aurelia project within a .NET Core project. The errors include 'Build:Cannot find name 'RequestInit'', 'Build:Cannot find name 'Request'', and 'Build:Cannot find name 'Response''.

https://i.stack.imgur.com/miLjr.png

After trying to resolve these errors by installing the package @types/whatwg-fetch, I now face issues with Aurelia CLI build as it throws errors like 'Duplicate identifier 'Headers'' and 'Duplicate identifier 'Request''. These conflicts seem to stem from whatwg-fetch and lib.dom.d.ts.

Despite updating tsconfig, the typings are not picked up correctly by Visual Studio, leading to conflicting builds. Adding the lib.dom.d.ts file directly to the files array in tsconfig resolves the errors, but I seek a more optimal solution.

Answer №1

It appears that many of the issues mentioned are ones I have successfully resolved in the past on Stack Overflow. You may want to check out this link to see if it can assist you: How to create aurelia typescript project with vs2017rc

You may have already addressed the majority of the problems outlined in the provided link, or perhaps they do not pertain to your specific situation with Aurelia CLI. Nonetheless, running this command: 

npm install <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="07737e77627464756e7773473529362932">[email protected]</a> --save
has proven helpful for me and others who have encountered similar errors related to URL and Fetch.

Answer №2

@mgiesa suggested that the most effective solution was to turn off Visual Studio's TypeScript compilation feature. This decision was made due to conflicting TypeScript settings between different build tools. Thankfully, handling this issue has been simplified with recent updates to Visual Studio.
