Lattr (later) is a small API driven Twitter scheduler, in practice, it would be something like a lite version of Buffer or Hootsuite. In the current version, posts can be scheduled using an API/Webhook, however, a Web/Mobile UI will come a little further down the line.
Webhooks are supported to allow automation with services such as IFTTT, webhook posts will be scheduled based on a specified time gap in hours with a randomized minute. You could then post every 2 hours, with some randomization on the exact minute of posting.
You could also provide a timestamp in the payload to specify a post time.
Additionally, you can configure a time range, too, for example, post only between 6 am and 6 pm, and optionally a daily post quantity, this would then calculate the hour based on allowed hours divided by total posts to post, thereby automatically scheduling up additional posts for the following day and potentially building up a long queue.
Things like analytics will not be added in, for that you could use services like Bitly to shorten your URL's and track if that way, once a web UI is added I will add in integrations with such services to automate the process.
In order to run the app locally you would need GoLang v1.16+.
To host the project there is a Docker file setup ready to be deployed, outside of that you would need a postgress database.
In either scenario you would need the following environment variables configured as well as Twitter API credentials.
In api/tables you will find the SQL scripts needed to be run to setup the database
Ensure your hosting environment is configured for the correct timezone, all times are relative to the environments configured timezone
CD into the api directory and run make run
Make sure you have the heroku CLI too installed and are logged in.
Run heroku stack:set container --app APP_NAME
You can then either add heroku as a remote to your project and push the code up, connect the heroku project to your GitHUb account for automated deployment.
How do I set the timezone on my dyno?
