# TapTempo
|
|
|
|
This small SQLPage example shows how to :
|
|
- save request logs to the database
|
|
- display graphs
|
|
- make computations on the database
|
|
- write a custom component with HTML and CSS
|
|
|
|
## TapTempo: a webapp to measure the tempo of a song
|
|
|
|
TapTempo is a webapp that lets you measure the tempo of a song by tapping on a button in rhythm with the music.
|
|
|
|
It is a simple example of a webapp that stores data in a database, and displays graphs.
|
|
|
|
### Implementation
|
|
|
|
At each tap, the webapp sends a request to the server, which stores the timestamp of the tap in the `tap` table.
|
|
|
|
A [window function](https://www.sqlite.org/windowfunctions.html) is used to compute the tempo of the song from the timestamps of the last two taps.
