Recently a project needs to use typeScript.
Would like to take this opportunity to review and review, step up, npm, and the use of webpack.
above sea level
npm init -y generates a simple package.json file
npm install install dependencies.
npm install [email protected] depends on the package to install the specified version
webpack
Overview:
The basic principle is to bundle a series of js files into one js. By the way, solve the dependency problem of js.
Webpack does not operate on js. If you use ecma2015 js, you need loader to convert js.
Basic operation:
run: webpack
mkdir webpack-demo && cd webpack-demo
npm init -y generate a simple package.json file
webpack scaffolding
npm install webpack webpack-cli --save-dev
browser auto refresh.
webpack-dev-server
introduces lodash: main For array processing.
npm install --save lodash
path.resolve(__dirname, 'dist')
Inside any module file, you can use the __dirname variable to get the full absolute path to the directory where the current module file is located.
