This provides the front end for the Astra Getting Started application. This is meant to be used with one of the following backends:
Create a free-forever Cassandra Database with DataStax Astra: click here to get started 🚀
- Connect a web application to one of four backends to demonstrate an end to end full stack application
- Demonstrate how to properly page results for an Astra Service
- node v8.1.0
- DataStax Astra database
A .env file is required before you can build the application. This file needs to be added to the root of the project and called .env. This file
contains all the environment variables required for the application. Currently there is only one required entry:
BASE_ADDRESS=http://localhost:5000/api
This value is where you put the relative address of the api.
In order to start this application you need to run:
npm install
and then
npm run start
You will know that this is correctly running when you see this message in your terminal:
ℹ ｢wds｣: Project is running at http://localhost:3000/
ℹ ｢wds｣: webpack output is served from /
ℹ ｢wds｣: Content not from webpack is served from /Users/dave.bechberger/Documents/projects/bechbd/getting-started-with-astra-ui
ℹ ｢wds｣: 404s will fallback to /index.html
If you would like to build this for deployment then this can be accomplished using:
npm run build
This is an example UI which connects to an Astra database.
Upon entering the application you will be prompted to add your credentials for the Astra database you want to connect to.
Once you have entered your credentials you will be given the option of either creating a new journey or replaying an existing one.
If you create a new journey, you will enter a name for it. Once you click launch the system will generate 1000 random sensor readings for each of the 4 sensors displayed (pressure, temperature, speed, location). These sensor readings will be written to the database. After the writes have begun the application will begin to read the sensors back in a paged manner and once data has been returned to the UI the system will begin the playback.
If you choose to replay an existing journey once you click on the journey to replay the application will begin to read the sensors back in a paged manner and once data has been returned to the UI the system will begin the playback.
