This is a web application in Vue demonstrates use of the Fetch API to talk to a REST server. There are two implementations of the REST server, one in Node.js (using Express) and one in Go (using gin). Both talk to a PostgreSQL database.
Install the Postgres database server.
On a Mac this can be done with brew install postgresql
assuming homebrew is installed.
# Initialize the database.
sudo mkdir /usr/local/pgsql
sudo chown {your-user-name} /usr/local/pgsql
initdb -D /usr/local/pgsql/data
# Start the Postgres server.
pg_ctl -D /usr/local/pgsql/data start
# Create the "postgres" user.
create user postgres (enter "postgres" for the password)cd go
go get github.com/gin-gonic/gin # REST server library
go get github.com/lib/pq # PostgreSQL driver
go run main.gocd server
npm install # installs all dependencies
npm run dbsetup # recreates database tables, losing data
npm start # starts Express servercd to the top project directory.
npm install # installs all dependencies
