Small long-polling client
This tool, provided with the django-realtime-rest, can be used to easily link a model (a simple javascript object) to data fed by the server through the use of a long-polling call.
Usage
To try it in node.js, just create an RTView object and then call monitor:
var realtime_rest = require('realtime_rest');
const rtView = realtime_rest.RTView('localhost:8000/api/my-models-rt/', function (data) {
console.log(data);
}, realtime_rest.nodeGet);
rtView.monitor();
If you work with angular, RTView can take a third parameter which will be the function used to perform the HTTP GET call:
const rtView = RTView('/api/my-models-rt/', function (data) {
$scope.evalAsynch(function () {
// Do something with the data, which is a Javascript object
});
}, $http.get);
rtView.monitor();
Get function
/!\ Note that by default, realtime_rest
will use the XMLHttpRequest
browser
function to perform the get request. If you use the tool on node, use the node
compatible function nodeGet
. You can also provide you own implementation of
get which shall follow the following specifications:
- It shall take a url as string
- It shall return a ES6 promise which resolve an object containing a data field which points to a JSON object:
{
data: '[{"myField": "foo"}]',
}
- It shall reject in case of error with an object like:
{
status: <status code>,
message: <error message>,
}
angular's $http.get
satisfies those requirements.
