cl-cookieweb

A cookiecutter web template for Common Lisp.

Provides a working toy web app with the Hunchentoot web server, easy-routes, Djula templates, styled with Bulma, based on SQLite, with migrations and an example table definition.

Featuring:

Recipe to run the project from sources or to build a binary, choosing your Lisp implementation
Test suite using Fiveam
DB:
- creation of a DB (SQLite by default. That is easily configurable)
- a simple models.lisp with a Product table definition with the Mito ORM (see Cookbook/databases#the Mito ORM)
- migrations (built-in Mito feature)
Djula templates
- showing inheritance and custom filters
- styled with Bulma
- showing a default dashboard
JavaScript:
- load static assets with a dummy JS file.
run the project:
- from sources
  - CLI args parsing (port, help)
  - port is also taken from an environment variable
- build a self-contained binary
  - (xxx: static assets not included?)
  - with Deploy: ship shared libraries, run on another machine (rely on libssl of the host system). You then have to ship the bin/ folder.
- Roswell integration to run the app as a script and to build, install and share binaries.
Systemd example

Based on cl-cookieproject: a ready-to-use project template.

Usage

Create a new project. You'll be prompted to provide some basic information about your new project, which will then be auto-generated in the current working directory:

$ pip install cookiecutter
$ cookiecutter https://github.com/vindarel/cl-cookieweb
project_name [cookie-web-project]:
repo_name [cookie-web-project]:
description []: A test project
version [0.0.1]:
year [1984]:
author [CL User]: me
email [me@mail.com]:
username [mme]:
branch [master]:
remote [origin]:
Initialised empty Git repository in /home/vince/bacasable/lisp-projects/cookie-web-project/.git/
Switched to a new branch 'master'

Run it straight away:

$ cd cookie-web-project
$ make run
rlwrap sbcl --load run.lisp
This is SBCL 2.0.10, an implementation of ANSI Common Lisp.

  Load 1 ASDF system:

  Load 1 ASDF system:

Application started on port 4242.

You can see the Hello from the main function, and we are given a Lisp REPL.

A bin/ directory is created with shared .so libraries:

$ ls bin
cookie-web-project  libz.so

(and when required, you'll find libmagic.so, libosicat.so etc)

Run the binary from the bin/ folder. We can see that Deploy handles loading those shared libraries.

$ ./bin/cookie-web-project

Systemd

Create a new file in /etc/systemd/system/webcookie.service:

[Unit]
Description=Lisp web project skeleton

[Service]
WorkingDirectory=/home/path/to/cookie-web-project/  # <- directory
ExecStart=/home/path/to/cookie-web-project/bin/cookie-web-project  # <- binary
Type=simple
Restart=on-failure
[Install]
WantedBy=network.target

Commands:

sudo systemctl start webcookie.service

and also stop and status.

To see logs:

journalctl -u webcookie.service

To start the app on (re)boot:

sudo systemctl enable webcookie.service

If you want to run the app from sources, you can use the command /usr/bin/make run, but tweak run.lisp so that it calls (run) instead of (main), so that the server thread is placed on the foreground. Otherwise, the Lisp process quits instantly and your process is not started.

cookiecutter options

You can use command line options: https://cookiecutter.readthedocs.io/en/1.7.2/advanced/cli_options.html

--no-input: do not prompt for parameters and only use cookiecutter.json file content
--replay: do not prompt for parameters and only use information entered previously
-f, --overwrite-if-exists: overwrite the contents of the output directory if it already exists
-s, --skip-if-file-exists: skip the files in the corresponding directories if they already exist
-o, --output-dir: where to output the generated project dir into
--config-file: user configuration file

CHANGELOG

2022/06: build with Deploy (handle shared libraries). Make ASDF not crash when running the binary on a system with an old configuration (it's a self-contained binary dude!).
- added Systemd service example.
2021/12: load a config.lisp init file before web startup. Same could be done with a post-init file.
init.
