This project requires Node v16.x.x (npm v8.x.x). You can use Node Version manager (nvm) to manage several versions of node...
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
nvm install 16
...and then you can do npm install etc as below.
You should also create an .env file and copy everything from .env.example into .env to properly preview the
static project.
# install dependencies
$ npm install
# serve with hot reload at localhost:8080
# NB: supports only 2 concurrent browser sessions, so more sessions may display strangely or not at all
$ npm run dev
# build for production and launch server
$ npm run build
$ npm run start# generate static project
# To view the statis website, it has to be hosted by a http server
$ npm run generate
# locally preview the static project
$ npm run start
