QUESTION
I'm trying to build a simple rest api in Lucerne, but the clack:call method fails if the json is malformed. So, I extended the bass-app class and added an around method:

& fast-http:cb-message-complete
seem to be the same symbol. I am leaving it here for posterity.]
You are not handling the right condition (and in fact I'm not sure you're handling a condition which exists at all, which I'd expect the system to have warned about perhaps, although perhaps it can't).
You need to handle fast-http.error:cb-message-complete
, but your handler specifies fast-http:cb-message-complete
. The first of these is a condition (defined here, while the second is I think implicitly define here and is not a condition but the name of a function I think.
A more general trick is to try to handle some much-too-general error: you will probably end up handling things you don't know how to handle, but if your handler gets invoked you know that the call stack looks like you think it does when the error is signalled. Then you can start handling the errors you actually care about. In this case that probably means fast-http.error:callback-error
I think.
QUESTION
I've recently successfully deployed a node.js server through Heroku, and the machine can be found here: https://congress-tracker-app.herokuapp.com/
It's basically communicating with Twitter's API, updating a .csv file every time it receives a tweet from my predefined set of parameters – in this case, the IDs of the tweets. I am then displaying that CSV using D3.js to visualize the data.
The data is being pulled in using the D3 javascript library...
d3.queue().defer(d3.csv, "public/data/twitterData.csv").await(update)
The update callback function is then passed the data, and creates my visualization.
I have two problems:
I cannot get the app to run in the background, AKA still update the CSV when the web page isn't open. I want the Twitter API to continue to communicate with my app, so the data will accumulate over time without someone having to keep the page open. It's being fetched with Twitter's stream API.
Reloading the app causes my CSV to clear back to a single row of data under the headers, which I entered in the initial build. Furthermore, when I clone the files to my desktop, the CSV in the public folder doesn't show any of the new data fetched from Twitter.
On the Heroku app page, my logs show that data is being added. The "file saved" message appears, which I have fire in my code when fs.appendFile adds a row to my CSV. Here's the message:
The CSV file, as you can see, sits in the public folder of my application. How can I ensure that after the app quits 1) the server continues to run and 2) the changes to my CSV are saved?
Here's part of my code:

Answered 2018-Feb-28 at 20:30I think the solution to your problem is kicking off a "Background Job" -- this gets your long-running application logic outside of the normal HTTP request/response cycle.
https://devcenter.heroku.com/articles/background-jobs-queueing
Heroku dynos have ephemeral filesystems -- meaning once you restart the app you will lose any temp files, including your CSV. You probably want to push this to a more permanent storage after your job completes.
