Basic Express app w/ a DB and set of APIs to do CRUD operations with.

h/t to this tutorial

Quickstart

docker compose up -d

http :/users

http post :/users name=Mary [email protected]

Using it with Kubernetes

shell into the container kubectl -n crud-app exec --stdin --tty postgres-67f98f6f96-t4gtx -- /bin/bash

then

root@postgres:/# su postgres
postgres@postgres:/$ psql

then psql -U salt -d api

then do what is in init.sql

Using TLS

To illustrate usage of certificates and keys (note that currently the included cert is for a domain I run in Cloudflare hence the no verify flag), run:

https :/users --verify no

NOTE: Handy tip...to use the non-root user's ENV VAR(s) with sudo, sudo --preserve-env=KEY,CERT docker compose up -d

Passing in your own TLS

To provide your own cert and key, set them as environment variables in your shell, run it using docker compose, and it'll pass the KEY and CERT as env vars to the Node process.

Building the Express app

cd app

./self-signed.sh to generate the cert and key referenced in the app.js file

docker buildx create --use

docker buildx build --platform linux/amd64,linux/arm64 \
 -t <your_docker_hub_account>/crud-app --push .

Using standard to enforce style guidelines

npm i standard

npm test to see guidance from standard package

npx standard --fix to apply the rules from standard in an automated way

Alternatively, you can run npm run fix which has been added to the package.json
