Unnecessary custom plugin dojo/request/default!

Reported by: Randy Hudson Owned by:

Our AMD support processes all plugins on the server and not in the browser. I don't know if anything actually uses dojo/request, but when we scan it we come across a plugin we don't know how to handle: dojo/request/default!.

Looking at default.js, it seems unnecessary. Instead, dojo/request should require: "./has!host-browser?./request/xhr:./request/node" or something similar.

dojo/request/default! is absolutely necessary for the interface to dojo/request to work correctly. The has switch you have put here would work, except that there is also a way to set the platform default through a configuration option. This means that any provider can be used as the default provider for an application. The most useful provider used in this configuration would be dojo/request/registry which allows providers to be registered for URLs or other criteria and then routing all requests through the dojo/request/registry function call. The end result is that library code can use dojo/request and be provider agnostic (much like how stores work). Since dojo/request is a new API as of 1.8, no library code currently uses it because of backwards compatibility, however moving forward any new library code that makes requests should use dojo/request.

Bryan, your comment just seems to highlight yes another solution to a problem that is already solved in AMD. If a client needs to customize the default implementation, this should be done via the common config:

    map: {
        '*': {
            'dojo/request': 'dojo/request/registry'

This way, when any module asks for "dojo/request", it would receive the dojo/request/registry module's implementation.

Would you please consider reopening this, or, if the config map approach isn't sufficient, explain why.

the map approach is interesting but one important point to note is that when the API for dojo/request was added, the map config was not part of AMD but plugins were. so the problem was solved with AMD... using plugins.

If dojo really intends to embrace AMD, then it seems like adopting the AMD solution would make sense here. Given how new dojo/request is, very few would have started using it and even fewer would have started replacing its implementation using "config-requestProvider".

What about deprecating the config-requestProvider property? dojo/request would then only reference the default! plugin if that property were in use, so its dependency would look something like:
