Architecture
Basic usage
EZStore has two HTTP API's: one to ingest data and one to retrieve it.
IoT devices can push their data to EZStore with a simple HTTP POST request containing a JSON document:
POST /ezstore/v1/metrics/{deviceId}
{
"temperature": 21.67,
"humidity": 65.10
}
To retrieve that data, simply do a GET request for the same deviceId:
GET /ezstore/v1/metrics/{deviceId}
{
"data": [
{
"temperature": 21.67,
"humidity": 65.10,
"timestamp": 1641286719828
}
]
}By default, a GET request will return data from the last 7 days. You can also define your own date range by using the start_date and end_date parameters:
GET /ezstore/v1/metrics/{deviceId}?start_date=2021-08-01&end_date=2021-08-31
Get started

Restricting access
By default, EZStore will happily serve any request.
If you want to limit access, implement a custom authorizer in the serverless.yml file.
TODO: give an example ;)
