Talk: Developing ClojureScript with Figwheel

Bruce Haumans's talk at Clojure/West is about Figwheel, his tool for compiling and auto-reloading ClojureScript in the browser.

Background

One of the characteristics of web development is that it is highly dependent on visual feedback. The various languages are loose enough in their semantics that it is hard to verify their correctness past how they look. Typically, you write some code then reload the browser to see the changes.

This can work, but each time you reload, you lose all of the Javascript state in the browser, which can make each change take a long time. Each time you reload, you have to reinstatiate the state, either manually or automatically. Figwheel solves this problem in a different way: whenever your ClojureScript file changes, recompile it and push it to the browser (over WebSockets). If you set the ClojureScript up right, your state will be preserved.

I have used Figwheel and it absolutely changes ClojureScript development. It's one of the first things I set up in a new ClojureScript project. This talk will explain how to work it into your workflow.

This post is one of a series called Pre-West Prep, which is also published by email. It's all about getting ready for the upcoming Clojure/West, organized by Cognitect. Conferences are ongoing conversations and explorations. Speakers discuss trends, best practices, and the future by drawing on the rich context built up in past conferences and other media.

That rich context is what Pre-West Prep is about. I want to enhance everyone's experience at the conference by surfacing that context. With just a little homework, we can be better prepared to understand and enjoy the talks and the hallway conversations.

Clojure/West is a conference organized and hosted by Cognitect. This information is in no way official. It is not sponsored by nor affiliated with Clojure/West or Cognitect. It is simply me (and helpers) curating and organizing public information about the conference.
