An incredibly simple JSON dashboard (parser?) for real-time telemetry data
- Get data from an HTTP endpoint [x] times in 1 second.
- Reserved key names for larger display and server-side uptime data
- Very, very simple and lightweight. It is so lightweight that you don't even need to define each key on the client side.
Clone the repo, then edit js/main.js file. You will notice 2 lines:
const RefreshRate = 2;
const APIEndpoint = "http://127.0.0.1:8078/api.json";
APIEndpoint is the API endpoint of your JSON API. Configure this to point your server.
RefreshRate is how many times the data is fetched in 1 second, similar to Hertz. For example, if it is set to 5, that means the data will be updated every 200ms (or 5 times in 1 second).
Configure them according to the needs, and you are ready!
The server must return a very simple JSON response. Example response can be found in example-api-response/api.json
All the keys (except named speed and uptime) will be displayed as a new sensor value. This allows to add and hide values directly on server-side code, without caring about client-side implementations. speed value will be displayed larger on the screen, and uptime will be displayed under the date in gray color. Please note that speed key is mandatory, but uptime key is optional.
Two different index files (named index.html and index2.html) are created. Simply, they are two different designs. Choose the best version for you and customize.
This project was actually created for an Efficiency Challenge Car contest, so variable names tend to be in that direction (like speed).
