Ubuntu install Vue.js

構築大綱：ubuntu > nvm > node.js + npm > @vue/cli > vue.js

構築步驟：
1. install nvm from it's github repository
2. install node.js by nvm and get npm at the same time
3. use npm to install vue-cli
4. use vue-cli to construct vue.js MVVM

步驟細節：
sudo apt-get update
sudo apt-get install build-essential libssl-dev
curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh
# go check https://github.com/nvm-sh/nvm for detail
source ~/.profile
# nvm --version
nvm install node
# node -v
# npm -v
npm serch @vue/cli
npm install -g @vue/cli
# you should use "-g" global install vue-cli and http-server
# then it will installed in ~/.nvm/versions/node/v12.7.0/lib/ as we wanted
# npm list -g
vue ui
vue create MyProjectName
npm run serve
npx vue-cli-service serve --https
npm run build --modern

前後端分離：
emacs vue.config.js
module.exports = {
    outputDir: '../templates',
    assetsDir: '../static',
}
