>Start (confirm that the node environment and npm package management tool have been installed)
1. Create a new project file named vuedemo
2. npm init -y Initialize the project
> install project dependencies
3. npm install --save vue The latest version of vue is installed by default
4. npm install --save-dev webpack webpack-dev-server Install webpack, webpack-dev-server (a small Node.js Express server)
*Extension: npm install When installing an npm package, there are two command parameters that can write their information into the package.json file, one is npm install --save and the other is npm install --save-dev. The difference is that --save will add the name of the dependent package to the dependencies key of the package.json file, and --save-dev will be added to the devDependencies key of the package.json file.
--save-dev is what you depend on when developing, - -save is something you still depend on after you publish. *
5. npm install --save-dev babel-core babel-loader babel-preset-es2015 Install babel. The function of babel is to compile the grammar of es6 into the grammar es5 recognized by the browser
6. npm install --save-dev vue-loader vue-template-compiler Components used to parse vue, files with .vue suffix
7. npm install --save-dev css-loader style-loader Used to parse css
Extension: css-loader and style-loader, the two handle different tasks, css-loader enables you to use methods like @import and url(...) to implement the function of require(), style-loader will all the calculated Styles are added to the page, and the combination of the two allows you to embed stylesheets in webpack-packaged JS files.
8. npm install --save-dev url-loader file-loader For packing files and pictures
9. npm install --save-dev sass-loader node-sass Used to compile sass
10. npm install --save-dev vue-router Install routing
> Edit the project directory and add code
11. The file directory is as follows;
//dist file is produced by executing webpack instructions later, don't care;
//webpack.config.js The configuration file itself is also a standard Commonjs specification module;
//routes.js file put routing configuration file;
//index.html home page entry file
//App.vue is the project entry file.
//main.js This is the core file of the project. The global configuration is configured in this file.
//Commponents directory contains public component header files.
//The views file is placed on the details page;
>code
//webpack.config.js

execute instruction
webpack
Execute webpack-dev-server:
webpack-dev-server
The browser opens the generated link: as I am here http://localhost :8083
Home page details page effect:
About the details page effect:
ok, I hope you can run through the project process at one time.
Supplement:
Convert webpack and webpack-dev-server commands to npm commands
安装 across-env:npm install cross-env --save-dev
npm install cross-env --save-devpackage.json file added
"dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",
"build": "webpack"
ok, execute the npm command npm run dev, the browser opens a new window (equivalent to pointing the npm dev command to the webpack-dev-server command);
npm run devExecute npm run build (equivalent to pointing the npm build command to the webpack command)
npm run build
Problems encountered:
1. An error is reported when the .sass file is imported externally, and the sass syntax in <style lang="sass"></style> compiles normally; (I blocked sass above) The
above ends.
===================2018/01 Notes ============================= ===
vue-cli builds vue project process
1. Download and install the node environment and npm package management tool; (node -v; npm -v to check the version);
2. npm install -g vue-cli; use npm to install vue-cli globally; (vue -V) (1. When installing vue-cli, webpack is already installed.)
3. vue init webpack projectname; generate project template (1. webpack is the template name, here we need to use the packaging function of webpack, so use webpack; 2. projectname is the project name)
4. cd projectname
5. npm run dev
6. npm run bulid
Note: The file directory path cannot be in Chinese, an error will be reported
