What it does
We're having a renaissance of CLIs - every programming language from Node.js to Go to less fashionable ones like .NET all have CLIs and developers love them. You should love them too and make sure your next CLI is a killer. CLIs (command-line interfaces) are text-based interfaces for your applications which are easily automated, fast to work with and can be combined with other CLIs to create workflows. Here's why I prefer the OpenFaaS CLI in Go over the Serverless Framework Inc Node.js CLI: With Go you can easily provide a single static binary that contains your whole application or CLI for your chosen platform.
