Joy is a full stack web framework written in janet
(use joy) (route :get "/" :home) (defn home [request] (text/plain "You found joy!")) (def app (app)) (server app 9001)
First make sure janet is installed
Next, install the joy cli like this
jpm install joy
joy executable will be on your path and ready to roll. If it isn't and you're like me and use homebrew, add this to your
export PATH=/usr/local/Cellar/janet/<your janet version here>/bin:$PATH
Then make sure you reload the profile:
Now, run the following from your terminal
joy new my-joy-project
This should create a new directory called
my-joy-project and it should create a few files and things
to get you started.
Now that we have a project set up, it's time to test it out in the browser:
This should start an http server that's listening at http://localhost:9001.
Next, let's create a database, a table and connect it with routes and a few functions for handling requests.
If you aren't already in the
my-joy-project directory, go ahead and get in there. Now run
joy create db
This creates a new empty database named
The default template doesn't assume you want a database so you'll need to connect to it in
; # main.janet (defn main [& args] (db/connect (env :database-url)) (server app (env :port)) (db/disconnect))
Run this to create a new migration with a table with a few columns:
joy create table account 'email text unique not null' 'password text not null'
This has created one file in your db/migrations folder that is waiting to get applied to the database.
Run this from your terminal
This will migrate your database and create a new file
In joy there are no ORMs, no classes, and no objects, just functions that take requests and return responses.
Let's generate a few routes for the table from earlier:
joy create controller account
Those commands have created another new file:
routes/account.janet and updated your
main.janet file with an import statement so the account routes get set up.
Go ahead and check out the new
account routes in the browser now:
Joy can do a lot more than that, check out the docs here
In order to make using joy more portable, we wanted to include a Dockerfile that creates an easy place for you to mount your code in and run joy without having to install anything or manage permissions on your local.
