Configuration

Sample code uses ES6 language features such as arrow functions and promises. For compatibility with IE11, code written with these features must be either transpiled using tools like Babel or refactored accordingly using callbacks.

Introduction

In order to use the JS-SDK, the library must be initialised with an api-key. The api-key is a key received upon subscription. The JS-SDK is a client library for web based consumers. As a reminder, the T1C can be used from a native applications context using a native client, or addressing directly the T1C interface. In order to work with an api-key in a browser context, 2 type of consumers can be distinguished:

• SPA (Single Page Application) integration: this is a web application without any back-end

• Web Application integration: this is a web application with a back-end implementation

For an SPA, an api-key (thus the access token to the Distribution Service) is considered unsafe in a browser context. For SPA's, Trust1Team configures extra security measures on infrastructure level. A mutual authentication is required and additional policies are applied (IP restriction policy, ...).

The api-key must be translated into an JWT token in order to enable communication with the T1C.

Initialise the client library

To initialise the JavaScript client library, the library must be loaded into your HTML page:

<script src="../T1CSdk.js" charset="utf-8"></script>

Once loaded, the script will expose a GCLLib global. This global will allow you to create a GCLConfig:

The GCLConfigOptions object will allow you to specify and/or override the configuration to be used. Configuration options can be found in the Configuration Options below. You can create a GCLConfigOptions as follows:

var configoptions = new T1CSdk.T1CConfigOptions(
            environment.t1cApiUrl,
            environment.t1cApiPort,
            environment.t1cApiUrl,
            environment.t1cApiPort,
            environment.jwt
        );
        
config = new T1CSdk.T1CConfig(configoptions);

Now that we have a configuration, we can initialise the client library. The following example creates a Promise that will resolve with an instance of a T1CClient:

T1CSdk.T1CClient.initialize(config).then(res => {
        client = res;
        console.log("Client config: ", client.localConfig)
        core = client.core();
    }, err => {});
