WeĪlso need to import the AngularJS libraries for use in our SPA.Ĭreating & Referencing the Angular App and Controller Objects To start with, create some CSS rulesets to modify the table, th, td, and tr elements to format the tables of data. Of our CSS, scripting, and Angular controllers in a single file, deliberately not engaging the functionality provided byĪngularJS services, factories, and custom directives.ĬSS Definitions & Importing AngularJS Libraries Since this is a simple demonstration, we will include all With the API Server setup completed, we are ready to build our SPA. See the help documentation for more information on supported OData queries. With other standard OData URL parameters, such as $filter, $orderby, $skip, and $top. Since we are working with Angular, we will append the parameter to the end of URLs that do not return JSON dataĪs with standard OData feeds, if you wish to limit the fields returned, you can add a $select parameter to the query, along URLs, you will need the address and port of the API Server. For information on accessing the tables, youĬan navigate to the API page for the API Server (click the API link on the top right of the API Server Web page). Below, you will see the URLs to access tables and the list of tables. Having configured a connection to Twitter, created a user, and added tables to the API Server, we can access OData feedsįor those tables. Select the tables you wish to access and click Save Changes. To enable tables, click the Add Resourcesīutton on the Resources tab of the Settings page. Having created a user, we are ready to enable access to Twitter entities as tables. The API Server with the read-only user, using the associated authtoken. We also allow connections from all IP addresses.Īs you can see in the screenshots, we already had a user configured with read and write access. Click Add, give the User a name, and select GET for the Privileges. Since we are only creating a simple SPA for viewing data, we will create a user that has read-onlyĪccess. You can add and configure users on the Users Next, create a user to access your Twitter data through the API Server. See the Getting Started chapter in the help documentation for a guide to using OAuth. Obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app. If you intend to communicate with Twitter only as the currently authenticated user, then you can To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own. You can connect using your User and Password or OAuth. Name your connection, select Other as the database, set the ADO.NET Provider (), and build a connection stringĪll tables require authentication. To configure the API Server to connect to your Twitter data, you will need to navigate to the Connections tab on the Set Access-Control-Allow-Headers to "authorization".Set Access-Control-Allow-Methods to "GET,PUT,POST,OPTIONS".Either click the checkbox to "Allow all domains without '*'" or specify the domain(s) that are allowed to connect.Click the checkbox to "Enable cross-origin resource sharing (CORS)". You will need to adjust the following settings. We can enable CORS by navigating to the SETTINGS Will need to run the application, configure the driver to connect to your Twitter data, and then configure the driver toĬreate OData feeds for any tables you wish to access in your SPA.ĪngularJS requires servers to have CORS (Cross-origin resource sharing) enabled. Once you have installed the API Server and the ADO.NET Provider for Twitter, you If you have not already done so, you will need to download the CData API Server. The SPA willĭynamically build and populate an HTML table. Up the CData API Server and creating a simple SPA that has live access to Twitter data. Single-page applications (SPAs) with access to live data from Twitter. With Angular, the CData API Server, and the ADO.NET Provider for Twitter (or any of 200+ other ADO.NET Providers), you can build AngularJS (Angular) is a structural framework for dynamic Web apps.
