    Purpose of this project

    This JavaScript library allows a developer to implement the Knora API without knowing technical details about it. We published this library as @knora/api on NPM for easy integration into JavaScript projects. The library is developed in TypeScript and declaration files are part of the package to allow for integration with other TypeScript projects.

    Changelog

    See file CHANGLELOG.md.

    Getting started

    Requirements

    This library has been written to be used in any JavaScript project. It may be integrated with any JavaScript framework/library of your choice, such as Angular, React, Vue.js, and more.

    We recommend to install this library through NPM. This will make sure that all dependencies are installed. At the moment, this library depends on rxjs, json2typescript, and jsonld.

    In order to be able to integrate this library, you should have a basic understanding of an Observable. All HTTP requests to Knora are performed using an Observable through the RxJS library.

    Installation

    Run npm install @knora/api --save in the root directory of your project.

    Starting example

    Below you may find a minimal example in TypeScript for the process of the user login.

    If your IDE does not automatically help you with imports, these are the necessary files for the basic example:

    import { KnoraApiConfig, KnoraApiConnection, ApiResponseData, ApiResponseError, LoginResponse } from "@knora/api";
    

    Now, we will set up an instance of the class KnoraApiConnection. This instance can be your gateway to all API requests. In most use cases, you will want to store this instance globally within your JavaScript application.

    // Set up a KnoraApiConnection instance. 
    // We suggest to do this at your app entrypoint and store the instance globally.
    
    const config: KnoraApiConfig = new KnoraApiConfig("https", "knora.org");
    const knoraApiConnection: KnoraApiConnection = new KnoraApiConnection(config);
    

    As soon as the basic configuration is done, you will be able to use the pre-defined methods provided by the KnoraApiConnection instance. For example, you can login a user with a password as follows:

    // Login the user to Knora.
    // The method subscribe() is provided with two anonymous functions: 
    // The first is launched in case of success, the second in case of failure.
    
    knoraApiConnection.v2.auth.login("user", "password").subscribe(
        (response: ApiResponseData<LoginResponse>) => {
            console.log("Login successful!");
        },
        (response: ApiResponseError) => {
            console.error("Login failed!");
        }
    );
    

    Our library makes sure that session data (token) is stored within the KnoraApiConnection instance. Any subsequent call after a successful login will be performed using the session.

    Test environment for Angular

    ./test-framework provides a ready-to-use test environment for Angular developers. See ./test-framework/README.md for further instructions.

    Scripts for testing and deployment

    This package provides the following short-hand scripts:

    1. npm run test: Runs the project's tests defined in ./karma.conf.js. The coverage data is saved into the ./coverage/ folder.
    2. npm run build: Builds the whole project without testing and puts the files into the ./build/ folder.
    3. npm run yalc-publish: Executes 2 and publishes the package to the yalc app store.
    4. npm run npm-pack: Executes 1, 2 and packs the ./build/ folder into an NPM tgz package. The package is moved into a ./dist/ folder.
    5. npm run npm-publish: Executes 4 and publishes the package to the NPM store (runs in dry-run mode).

    Note: You need to install yalc globally by npm install yalc -g to use script number 3. In order to publish a package to NPM, you need to be logged in to NPM and you have to update the version in the package.json.

    For further development with Knora the following scripts can be used:

    1. npm run integrate-admin-code <path-to-generated-client-code: integrate generated code for the Knora Admin API, see https://docs.knora.org -> internals -> development -> generating client apis (use it without mock=true).
    2. npm run integrate-v2-test-data <path-to-generated-client-code>: this scripts integrates JSON-LD test data for Knora API v2.
    3. npm run expand-jsonld-test-data: creates versions with expanded prefixes for Knora API v2 JSON-LD test data. see https://docs.knora.org -> internals -> development -> generating client apis (use it without mock=true).

    Publish a new version to NPM

    Run npm run npm-publish as described above. The command runs npm publish in dry-run mode. If everything looks good, remove the flag --dry-run from package.json and run npm run npm-publish to publish the new version.
