Jasper is a tool that allows you to view GitHub issues and pull requests with flexible criteria. For example, you can browse issues and receive update notifications for issues with conditions such as "pull requests you create" or "issues with a nodejs/node bug label".
We call this functionality "Stream" in Jasper, and we can set up a Stream with the following query to view an issue with the conditions described above
repo:nodejs/node label:bug is:issue
Stream is powered by the GitHub Search API, which allows you to use very powerful queries. For example, the following query.
Jasper is a tool that belongs to category 1. Normally, tools in this category use the GitHub Notification API. However, Jasper is built using the GitHub Search API, which gives it a lot of flexibility not found in other tools. On the other hand, it may not be as easy to use as other tools. That's why Jasper has been developed with a balance between flexibility and simplicity in mind.
