What directories are needed for vue build

Directories required for vue construction: 1. build (build script directory); 2. config (project configuration directory); 3. node_modules (project dependent module directory); 4. src; 5. static (static resources Directory); 6. components (component directory) and so on.

The operating environment of this tutorial: windows7 system, vue2.5.2 version, DELL G3 computer.

VUE project construction and directory description

1. Install the node environment

1. The download address is: https://nodejs.org/en/

2. Check whether the installation is successful: If the version number is output, it means we installed the node environment successfully

　

3. In order to improve our efficiency, we can use Taobao’s mirror: http://npm.taobao.org/

Enter: npm install -g cnpm –registry=https: //registry.npm.taobao.org, you can install the npm image. If you use npm in the future, just use cnpm instead.

　

Check whether the installation is successful:

　

2. Build the vue project environment

　1. Install vue-cli globally

npm install --global vue-cli

　

##　2. Enter your project directory,Create a new project based on webpack template

　

　

　Description:

　　Vue build ==> Packaging method, press Enter That’s it;

　　Install vue-router ==> Whether you want to install vue-router, you must use it in the project, so Y Enter;

　　Use ESLint to lint your code ==> ; Do we need js syntax detection? Currently we don’t need it, so n press Enter;

Set up unit tests ==> Whether to install unit testing tools, currently we don’t need n press enter; e2e tests with Nightwatch ==> Do we need end-to-end testing tools? Currently we don’t need n and press Enter;

　3. Enter the project: cd vue-demo, install dependencies

　

After successful installation, there will be an additional directory in the project folder: node_modules

　

　4. npm run dev, start the project

The project started successfully:

3. Vue project directory explanation

##　

　1. Build: Build script directory

　1) build.js ==> Production environment build script;

　　2) check-versions.js ==> Check npm, node.js version; <br>　 3) utils.js ==> Build related tool methods;

4) vue-loader.conf.js ==> Configure the css loader and automatically add prefixes after compiling css;

5) webpack.base.conf.js ==> Webpack basic configuration ;

　 6) webpack.dev.conf.js ==> webpack development environment configuration;

7) webpack.prod.conf.js ==> webpack production environment configuration;

2. config: project configuration

1) dev.env.js ==> Development environment variables;

2) index.js ==> Project configuration file ；

　 3) prod.env.js ==> Production environment variables;

3. node_modules: project dependent modules loaded by npm

4. src: here is The directory we want to develop, basically everything we need to do is in this directory. It contains several directories and files:

1) assets: resource directory, where some pictures or public js and public css are placed. The resources here will be built by webpack;

2) components: component directory, the components we write are placed in this directory;

　3) router: front-end routing, the routing path we need to configure is written in index.js;

　4) App.vue: root component;

　5) main.js: Entry js file;

5. static: static resource directory, such as pictures, fonts, etc. Will not be built by webpack

6. index.html: Home page entry file, you can add some meta information, etc.

7. package.json: npm package configuration file, defines the npm script of the project , dependency packages and other information<br>

8. README.md: Project description document, markdown format

9. .xxxx files: These are some configuration files , including syntax configuration, git configuration, etc.

4. Start our first vue project

　1. Create a new one in the components directory views directory, which contains our vue component

1) Start our first component:

a: Create a new First.vue

in the views directory b: In Configure the routing path in index.js under the router directory

#　d: Enter ip: http://localhost:8010/#/first, check the page effect

　　

　　Note:

　　Under one component There can only be one parallel p. The following writing is wrong:

　　　

　2. Talk about parent-child components

　　1) Create a new sub folder in the components directory to store reusable sub-components. For example, create a new Confirm.vue component

　　

　　3) Introduce the sub-component

　　Introduction: import Confirm from '../sub/Confirm'

Registration: After the name code block in the

<script></script>

tag, add components: {Confirm}

Usage: In

Add

Complete code:

2) Parent-child component communication

Child component:

Parent component:

3. Use routing to build Single-page application

　1) Follow the above method to create a new Second.vue component

　　2) Route jump: Go to the second one Page

　　

　　

　After the route jumps, pay attention to the path changes:

　　

You can see that it is parsed into a tag in html

Here is just a brief introduction to the use of routing. For more detailed information, Please go to the official website to learn: https://router.vuejs.org/zh-cn/

4. How to write styles with less

1) Install less dependencies: npm install less less-loader --save

　　

　　After successful installation, you can see in package.json that 2 more modules have been added:

　　

　　2) Write less

　　

　

5. Supplement

　1. Solve the problem that vue cannot automatically open the browser: When we enter npm run dev to run the project, the command line prompts us that the operation is successful, but the browser does not open automatically and we can only enter it manually.

Solution:

1) Open config ==> index.js

2) Find autoOpenBrowser in the module.exports configuration, The default setting is false

　　

　　3) Change autoOpenBrowser to true

　　　

　　4) Ctrl C, and then we restart Click and the browser will open automatically

　　

　2. In order to avoid port conflicts, you can also modify the port and open the directory as above

　　

Modification successful:
