Problems using the TypeScript SDK in Cloudflare Worker

[kulla]

For fast prototyping we wanted to use Cloudflare workers which should speak to the enmeshed connector. However since the TypeScript SDK uses axios it cannot be used inside a Cloudflare worker since it only supports the fetch API (see axios#2507 and axios#1219). There are problems reported with NextJS and Amazon AWS as well. However for the next version of axios (see axios#4209) a fetch-based adapter might be implemented (see trello board -> fetch based adapters are "Potential issues to be added"). I had a look into the SDK and I see some workarounds:

• Using node-fetch or isomorphic-fetch instead of axios.
• Have a abstract class HttpClient similar to AxiosInstance with only the methods which are actually used by the SDK. Now there could be a FetchHttpClient and AxiosHttpClient. Consumers can decide which of both they want to use.
• Wait until axios supports fetch (maybe it will be in the next version already).
• ...

In our case it is a low priority issue. For accessing the enmeshed connector we will use a dedicated micro service running in its own docker container so that we will not have this issue. That's also the reason why I haven't created a feature request. However I wanted to document this somewhere. So other developers will not get the same error as we did.

Thanks, we will look into.

Waiting for axios to fix this seems to be a good option, we keep the dependencies up to date anyway!
