Persistent User Storage?

markmcintyre · October 12, 2022, 3:24pm

I’d like to create an applet where I compare a runtime value to the previous time that the applet executed. For example, getting a number of sales from a user account, and then showing a celebration on the day when the user passes a certain sales figure for the first time (but not on subsequent days).

Is there a way to store per-user data in this way?

@markmcintyre, I think you could accomplish this using the cache Pixlet module linked below. Of note, each user’s cached data must have a name unique to them. If it’s the same, then every user of your app will pull the same cached data down from the Tidbyt server. If the data is sensitive, or otherwise not already publicly available, I wouldn’t recommend this method though.

# Module reference

Pixlet scripts have access to a couple of modules that can be very
helpful in developing applets. To make use of a module, use the `load`
statement.

The example below would load the `render.star` Starlark module,
extract the `render` identifier and make it available to the script
as the symbol `render`.

```starlark
load("render.star", "render")
```

It's also possible to assign the identifiers to a different symbol. In
this example, the `render` module is made available to the script as
the symbol `r` instead of `render`:

```starlark
load("render.star", r = "render")
