Slack is not only the fastest growing startup in history, but it's also an app by the same name and one of the most popular communication tools in use today. We use it extensively at MongoDB to foster efficient communications between teams and across the company. We're not alone. It seems like every developer I encounter uses it in their company as well.
One interesting thing about Slack (and there are many) is its extensibility. There are several ways you can extend Slack. Building chatbots, applications that interface with the communication service and extending Slack through the introduction of additional commands called "slash commands" that enable Slack users to communicate with external services. In this article, we'll build a simple slash command that enables users to store and retrieve data in and from a MongoDB database. I'm always finding interesting information on the internet that I want to share with my team members so let's build an application we'll call URL Stash that will store interesting URLs for later retrieval via a Slack slash command. Now, follow along in the video below or skip over the video and read on for the details.
Create a Slack App
Start by logging into your slack team, or you can create a new one for testing. Visit the Slack API Console to create a new Slack App.
