The project structure

technology

First, REM adaptation

Installing a plug-inyarn add amfe-flexible postcss-pxtorem -S

amfe-flexibleIs to configure a scalable layout scheme, mainly by setting 1 rem to viewWidth / 10
postcss-pxtoremPostcss is a plugin for generating REM units from pixel (PX) units

In the main. Ts importamfe-flexible

import "amfe-flexible";
Copy the code

inpostcss.config.jsconfigurationpostcss-pxtorem

module.exports = {
  plugins: {
    "postcss-pxtorem": {
      rootValue: 37.5.propList: ["*"],}}};Copy the code

RootValue is set by dividing the width of the design draft by 10. Assume that the design draft is 375, that is, rootValue is set to 37.5
PropList is to set the attributes to be converted. This * means to convert for all units (px)

2. Add a CSS prefix

Installing a plug-inyarn add autoprefixer -D
inpostcss.config.jsconfigurationautoprefixer

module.exports = {
  plugins: {
    autoprefixer: {
      overrideBrowserslist: ["Android 4.1"."iOS 7.1"].grid: true,}}};Copy the code

OverrideBrowserslist: compatible configuration for browsers
Grid: true for IE enable grid layout prefix

Common components are written in TSX syntax

// svgIcon.tsx
import { defineComponent, computed } from "vue";

export default defineComponent({
  name: "svgIcon".props: {
    name: {
      type: String.required: true,}},setup(props) {
    const iconName = computed(() = > ` #${props.name}`);
    return () = > (
      <>
        <svg class="icon" aria-hidden="true">
          <use xlinkHref={iconName.value}></use>
        </svg>
      </>); }});Copy the code

DefineComponent encapsulates the setup function and returns the options object, giving the component the correct argument type inference under TS
<use xlink:href={iconName.value}>Need to change to hump form<use xlinkHref={iconName.value}>Otherwise there will be grammar problems

Four,`<script setup>`Syntactic sugar

1. The parent component passes the value to the child component

<! -- Parent component's HTML -->
<List :showTitle="false" :params="params"></List>
Copy the code

// 
interfaceProps { showTitle? :boolean; params? :object;
}
const props = withDefaults(defineProps<Props>(), {
  showTitle: true.params: undefined});Copy the code

definePropsDefining the props type
withDefaultsProvides the props default value
The two<script setup>Inside can be used without additional import

2. Child components pass values to parent components

<! -- Parent component's HTML -->
<LabelSelect @changeLabel="changeLabel" ref="label"></LabelSelect>
Copy the code

// The parent component 
const changeLabel = (labelName: string) = > {
  params.type = labelName;
};
Copy the code

// 
const emit = defineEmits(["changeLabel"]);
emit("changeLabel", labelName);
Copy the code

defineEmitsDefines the method name of the response parent component that needs to be defined before it can respond via emit()
emit('changeLabel', data)ChangeLabel is the method name of the response, and labelName is the value to be passed to the parent component

3. Logic reuse

With the use… Start with a hump. Define a useClickLike function and export it.

// useClickLikes.ts
import { ref, computed } from "vue";

function useClickLike(requestApi: Function) {
  let currentId = ref(""); / / the current ids
  let isLike = ref(false); // Whether to like
  let likeList = ref<string[] > ([]);// Thumbs-up list

  const handleLikes = (id: string) = > {
    if (likeList.value.includes(id)) {
      isLike.value = true;
      likeList.value.splice(likeList.value.indexOf(id), 1);
    } else {
      isLike.value = false;
      likeList.value.push(id);
    }
    currentId.value = id;
    return requestApi({ _id: id, isLike: isLike.value }).catch((err: any) = > {
      console.log(err);
    });
  };

  return {
    handleLikes,
  };
}

export default useClickLike;
Copy the code

Reference it in a VUE file, go in first, and then deconstruct the function logic you need

import useClickLike from "@/useMixin/useClickLike";
// Like logic
const { handleLikes } = useClickLike(apiUpdateLikes);
Copy the code

HandleLikes can be used directly in HTML templates

<div class="footer-item" @click.stop="handleLikes(item._id)"></div>
Copy the code

4. Use of computed and watch

import { computed, watch } from 'vue'

const getLikesNumber = computed(
    () = > (id: string, likes: number) = >
      likeList.value.includes(id) ? likes + 1 : likes
  );

watch(props.params, (NewVal, oldVal) = > {
    pageindex.value = 1
    hasLoad.value = false
    loading.value = false
    finished.value = false
    list.value = []
    getBlogList()
  })
Copy the code

For computed syntax, like vue2, watch syntax is slightly different: props. Params is the object to listen on, newVal is the latest value to listen on, and oldVal is the old value
Specific grammar can see the official document: v3.cn.vuejs.org/api/compute…

5. Use of VUex

import { useStore } from "vuex";

const store = useStore();
// Get the getLabelList method under the Label module actions
const getLabelList = () = > store.dispatch("label/getLabelList");
getLabelList(); // Execute the method directly
// Get the labelList attribute under the label module getters
const labelList = store.getters["label/labelList"];
Copy the code

Other specific usage please refer to the official document: next.vuex.vuejs.org/zh/guide/mo…

6. Use vue-Router

Configure the routing file,createWebHashHistoryMaking hash Patterns
/:pathMatch(.*)*Match all routes for redirection
This parameter is used to import a routing fileimport.meta.globCan not be used directlyimportImport,importThis is fine at development time, but the packaged file will not recognize the routing file

import { createRouter, createWebHashHistory, RouteRecordRaw } from "vue-router";
import Tabbar from ".. /components/tabbar";
// Identify all views/ folder name/*.vue files
// Only /views/ folder name/*.vue can be identified
const modules = import.meta.glob(".. /views/*/*.vue");
const loadComponent = (component: string) = >
  modules[`.. /views/${component}.vue`];

const routes: Array<RouteRecordRaw> = [
  {
    path: "/home".component: loadComponent("home/index"),
    meta: {
      title: "Home page",}},... {path: "/:pathMatch(.*)*".redirect: "/home",},];const router = createRouter({
  history: createWebHashHistory(),
  routes,
});

export default router;

Copy the code

Gets the Query parameter carried by the route

import { useRouter } from "vue-router";
const route = useRouter();
const id = route.currentRoute.value.query["id"];
Copy the code

The back-end service

You must first open the back-end service interface and connect to the MongoDB database, otherwise the front-end project cannot be previewed. The service interface here is actually reusing the interface of the WALL-blog project on the PC side. So if you want to add data in the admin background, you need to move to the repository: github.com/Sujb-sus/vu… .

There are three projects in this warehouse: PC management terminal (admin), PC client, and background server. Server project is actually the server directory of this project, in order to facilitate everyone’s preview, I Copy a Copy over.

Client: the PC side of a blog
Admin: blog management end, is used to add article data, tag data and so on
Server: Provides interface service data to blogs

Enable the back-end interface service

Method 1: Move to the warehouse address mentioned above

The warehouse is described in detail, and the main process is as follows:

View precautions, first install and connect the localMongoDBDatabase, start the service
Start theadminProject, you can manually add data through the management background

Method 2. Connect directly in this project`MongoDB`The database

Before starting the project, install the MongoDB database locally.
Configure the database name, user name, and password in the server/config.js file. The information can be customized, but needs to be synchronized with Step 3.

// server/config.js
export default {
  env: process.env.NODE_ENV,
  port,
  auth,
  log,
  mongodb: {
    username: "wall".// Database user
    pwd: 123456.// Database password
    address: "localhost:27017".db: "wallBlog".// Database name}};Copy the code

Start localmongoService to initialize the database inserver/config.jsSome necessary information for configuration;

> mongo // Start the mongo service
> show dbs // Displays the database list
> use wallBlog // Create a wallBlog database
> db.createUser({user:"wall".pwd:"123456".roles: [{role:"readWrite".db:'wallBlog'}]}) // Create a wall user in wallBlog database with password 123456
> show users // Show which users the library has
> db.auth("wall"."123456"); // The database authenticates the user and password. 1 is successfully authenticated
Copy the code

Enter theserverDirectory, install dependencies, and start services

cd server // Enter the server directory
yarn // Install dependency packages
yarn server // Enable the back-end interface. If the interface succeeds, the database connection is successful
Copy the code

Matters needing attention

env.d.tsFiles: Modules written in TS are still published in JS, so you need a D.ts file to mark the type of a js library surface object
models/index.tsFile: Used to define the type of data returned by the interface. Each data type needs to be defined, otherwise there will be problems when packaging THE HTML rendering data of the VUE file. The export needs to beexport type {... }Format export
components/noData.tsxFile: When referencing a static image, you need to import it in the form of a module import. When using the image path directly in HTML packaging, the image path will not be automatically resolved
styles/common/iphone_x.scssDocumentation: provides bottom spacing for the iPhonex full screen series
tsconfig.jsonFile: strict: true Enables all strict type checks
