Is Aurelia-Fetch reliant on whatwg-fetch as a dependency in its codebase?

I am currently in the process of updating my Aurelia project from a beta version to the March version.

One of the issues I encountered is:

Cannot locate name 'Request'.

Searching online led me to this problem on GitHub: https://github.com/aurelia/fetch-client/issues/65

This particular issue suggests that the solution is to install the TypeScript definitions for whatwg-fetch. After installing those definitions, the error disappears.

However, does this mean I also require whatwg-fetch? (Checking my node_modules directory, whatwg-fetch is not present.)

Answer №1

aurelia-fetch-client utilizes the Fetch API. The whatwg-fetch serves as a Fetch polyfill, making it unnecessary for the fetch client to rely on the polyfill. Moreover, the choice of polyfill varies depending on the module loader being used.

JSPM/SystemJS applications utilize the fetch polyfill from GitHub, whereas most other module loaders employ whatwg-fetch.

Therefore, while installing whatwg-fetch is essential, there are valid reasons why the aurelia-fetch-client does not have a direct dependency on it.
