Using an External DB

Your project may require a more complex data structure than our datastores. If a key-value store works, we strongly recommend using the built-in datastore to take advantage of language functions.

If you already have (or otherwise require) an external database, any external database that provides a REST API can be used. For the purposes of this tutorial, we will be using restdb.io.

Set Up

  1. Create a new database.

  1. Select Developer Mode in the upper right, and then choose Collections +

  1. Grab your API Key by clicking on API Docs and finding the value labeled x-apikey:. Save it as a function in your Dark canvas.

  2. Optionally, also grab the URL at the top of your page (in my case, its https://mydatastore-e7f9.restdb.io/rest/mydata) and save it as another function in your Dark canvas.

POST a New Record

  1. Create your header by doing a Dict::merge on HttpClient::jsonContentType and a dict containing your API Key

  2. Write an HttpClient::post using your URL, your fields (note: the field names are case sensitive) and your header, and then run it.

  1. Your data will appear in the restdb.io console.

GET All Data

  1. Create your header by doing a Dict::merge on HttpClient::jsonContentType and a dict containing your API Key.

  2. Write an HttpClient::get using your URL and header, and then run it.

  1. Your handler will return all of the data in your database.
