Serverless Clojurescript Workshop

This is the starting template for the serverless workshop.

Getting started

• Install lein
• Install node via NVM
• Install serverless npm install serverless -g

Note: initial template generated using

serverless create --template aws-nodejs

You can delete, edit or create a new one if you know what you're doing.

Quickstart

Are you an EMACS user? Great, I got you.

npm install serverless -g
npm install
npm run offline

Open core.cljs in emacs, make a change and save the file.

In a new terminal tab:

npm run node-watcher

In a new terminal tab:

lein repl

In emacs:

M-x cider-connect

In the REPL:

user> (go!)

Boom! You've now got figwheel, auto prod builds and serverless offline ready for cURL-ing.

REPL usage

These are the auto-generated docs for using the REPL.

Standalone Usage

1. lein figwheel
2. (In another window) node target\js\compiled\cljs_serverless_workshop.js ...

Production Builds

1. lein cljsbuild once prod
2. node server.js ...

REPL Usage (Vim)

You can now connect to Figwheel's REPL through Piggieback using vim-fireplace:

1. lein repl
2. (fig-start)
3. (cljs-repl)
4. (In another window) node target\js\compiled\cljs_serverless_workshop.js ...
5. (In Vim) :Piggieback (figwheel-sidecar.repl-api/repl-env)

Standard vim-fireplace commands will now work in the context of the Figwheel process:

• cqp to send a command from Vim to the REPL
• cpa... to evaluate a form without saving or reloading the file
• etc.
