HERE Data SDK for TypeScript contains several examples that demonstrate some of the key use cases:

• Authorization example – build the Data SDK using webpack and work with the APIs from @here/olp-sdk-dataservice-api. You can use this example application to find the list of groups that you have access to as well as create groups.
• React App example – use the Data SDK and React in a browser and learn how to work with the following modules: olp-sdk-authentication, olp-sdk-dataservice-read, and olp-sdk-dataservice-write.
• Node.js example – work with the Data SDK in Node.js and learn how to get data from versioned layers and save it to files.
• MultiPartUploadWrapper example – use the Data SDK to upload and publish a large amount of data in a browser.
