At Transposit we’ve found that even the simplest applications require a modest amount of state tracking. A ton of apps use AirTable, DynamoDB, Google Sheets, or the like to store a tiny bit of data. We wanted to make building apps even easier, so we created the Application Stash, a simple key-value store that is built right into the Transposit platform.
Need to track something like a timestamp? You can accomplish that with just a single line of code using the stash, which is what I ended up doing.
When I was building a Twilio-based application, I needed to aggregate a bunch of incoming messages before sending myself a text digest. I didn’t want my phone to be buzzing more than once every hour, so I used the stash to keep track of a timestamp corresponding to the last time my application actually sent me a text. With this timestamp, I could easily make sure that at least one hour had passed since the last digest.
The gist of my spam minimizing code is here:
The programmatic interface to the stash is pretty simple--think Map or dictionary in some common programming languages like Java and Python. Use
stash.put(key, value) to store any value that is JSON-serializable, and use
stash.get(key) to grab it out of the stash later.
Each app actually has two associated stashes: one in development and one for deployed applications. The development context is used when you’re moving fast-and-loose in the management console building, exploring, and iterating on your Transposit operations. Once it’s game time and you’ve deployed a polished operation, then the production context is used whenever deployed operations are executed.
The development stash can be viewed and managed under Code > Development > Stash.
Meanwhile, the production stash is under Deploy > Production Stash (note the different values between the two contexts!).
