As Dojo moves toward its 2.0 release, our focus has been on giving developers tools that will help them be productive in any JavaScript environment. This means creating consistent APIs across all environments. One area that has been sorely lacking, in this regard, is Dojo’s IO functions. We’ve always provided developers with a way to make requests in the browser (dojo.xhr*, dojo.io.iframe, dojo.io.script), but the API has been less consistent than some of us would like (dojo.xhrGet, dojo.io.script.get, etc.). Additionally, we’ve never provided a server-side implementation, and if we had, it would have been another module name and API call to remember.
With the release of Dojo 1.8, we have introduced the dojo/request API which provides consistent API calls between browsers, request methods, and environments:
require(["dojo/request"], function(request){
var promise = request(url, options);
promise.then(
function(data){
},
function(error){
}
);
promise.response.then(
function(response){
},
function(error){
}
);
request.get(url, options).then(...);
request.post(url, options).then(...);
request.put(url, options).then(...);
request.del(url, options).then(...);
});
