As part of his TypeScript presentation at SharePoint Conference 2012, Rob Bogue had to do a lot of work with the new REST API's for SharePoint 2013 (as we all did). Not happy to simply sling a bunch of JavaScript and call it a day, Rob took things a step further and created a reference library implementation to make things a bit easier on all of us.
Wiring up a REST query from a provider-hosted app to SharePoint 2013 looks like this if you set up the call and handle results manually:
var executor = new SP.RequestExecutor(appWebUrl);
var reqUrl = appWebUrl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('" + myList + "')/items?$select=Title&@target='" + hostWebUrl + "'";
executor.executeAsync({
url: reqUrl,
method: "GET",
headers: { "Accept": "application/json;odata=verbose" },
success: function (result) {
var objData = $.parseJSON(result.body);
response($.map(objData.d.results, function (item) {
return {
label: item.Title
}
}));
},
error: function (result, code, message) {
alert(message);
}
});
Using SP REST, the syntax is much cleaner and easier to read (and if you're using TypeScript you also get full Intellisense support):
obj.list.GetItemsByQuery([
{
field: 'Title',
operator: 'eq',
value: obj.myValue
}]).done(function (items) { //Do Something Here });
Rob is releasing SP REST to the community and is asking for contributors to help take the project forward. If you're interested, contact Rob via his blog and jump on the SP REST bandwagon.
