Authentication library

Overview

This repository contains all methods and classes that are required to request an access token for the OAuth authentication.

`UserAuth`

Description

You can use the UserAuth class instance with your authentication data to get a client access token.

Configure

To create the UserAuth class, pass the configuration object to the constructor.

const auth = new UserAuth(config);

Use with Local Authorization

To use the UserAuth class with local authorization:

Create the UserAuth class instance before instantiating any data sources.

/**
 * The function gets the access token.
 *
 * You can provide your own implementation or use one from `@here/olp-sdk-authentication`.
 *
 * There are two functions that work for the browser and Node.js.
 * For the browser, `UserAuth` uses `requestToken()` from requestToken.web.ts.
 * For Node.js,`UserAuth` uses `requestToken()` from requestToken.ts.
 *
 * When a function imports a function using `import { requestToken }` from "@here/olp-sdk-authentication"`,
 * the code automatically applies to the corresponding function.
 *
 * The following code is applicable only for Node.js.
 */

import { UserAuth, requestToken } from "@here/olp-sdk-authentication";

const userAuth = new UserAuth({
    env: "here",
    credentials: {
        accessKeyId: "replace-with-your-access-key-id",
        accessKeySecret: "replace-with-your-access-key-secret"
    },
    tokenRequester: requestToken
});

Get the access token.

const token: string = await userAuth.getToken();

Use with Credentials Imported from a File (Node.js)

In Node.js, you can use the UserAuth class with credentials imported from the credentials.properties file.

To use the UserAuth class with the credentials imported from the file:

Download your credentials.properties file from the HERE platform website.

Create the UserAuth class instance and set the path to the file with your credentials.

import {
    UserAuth,
    requestToken,
    loadCredentialsFromFile
} from "@here/olp-sdk-authentication";
const credentials = loadCredentialsFromFile(
    "replace-with-your-path-to-credentials.properties"
);
const userAuth = new UserAuth({
    credentials,
    tokenRequester: requestToken
});

Your credentials.properties file should match the following format:

here.user.id = "your-here-user-id"
here.client.id = "your-here-client-id"
here.access.key.id = "your-here-access-key-id"
here.access.key.secret = "your-here-access-key-secret"
here.token.endpoint.url = "your-here-token-endpoint-url"

Get the access token.

const token: string = await userAuth.getToken();

Generate a Bundle

If you want to have a compiled project, you can use bundle commands. After running each of the following commands in the @here/olp-sdk-authentication folder from the root folder, you get the JavaScript bundled files.

To get bundled files with a source map, run:

npm run bundle

To get a minified version for production, run:

npm run bundle:prod

To get bundled and minified JavaScript files, run:

npm run prepublish-bundle

Use a Bundle from CDN

Add the minified JavaScript file to your HTML and create the userAuth object.
