Developing

This plugin contains both a server and web app portion.

Use make dist to build distributions of the plugin that you can upload to a Mattermost server for testing.

Use make check-style to check the style for the whole plugin.

Server

Inside the /server directory, you will find the Go files that make up the server-side of the plugin. Within there, build the plugin like you would any other Go application.

Web App

Inside the /webapp directory, you will find the JS and React files that make up the client-side of the plugin. Within there, modify files and components as necessary. Test your syntax by running npm run build.
