I am creating my design portfolio using Vue CLI 3. The architecture of my website is very simple. I have a home page, about page, work page, and several individual project pages:
Home
About
Work
Project
Project
Project
The work page consists of several links that would click through to the individual project pages. The work component is set up like so:
<template>
<div>
<projectLink v-for="data in projectLinkJson" />
</div>
</template>
<script>
import projectLink from '#/components/projectLink.vue'
import json from '#/json/projectLink.json'
export default {
name: 'work',
data(){
return{
projectLinkJson: json
}
},
components: {
projectLink
}
}
</script>
As you can see, I'm importing JSON to dynamically render the content. Next, the projectLink component can be seen in the code block below. Within this component I am passing a param into <router-link> called projectName
<template>
<router-link :to="{ name: 'projectDetails', params: { name: projectName }}">
<h1>{{ title }}</h1>
</router-link>
</template>
<script>
export default {
name: 'projectLink',
props: {
title: String,
projectName: String
}
}
</script>
My routes.js file is setup like so:
const routes = [
{ path: '/', component: home },
{ path: '/about', component: about },
{ path: '/work', component: work },
{
path: "/work/:name",
name: "projectDetails",
props: true,
component: projectDetails
},
];
and my JSON is like so:
{
"0": {
"title": "test",
"projectName": "test"
}
}
Lastly, my projectDetails component is the component that is where I am having this issue:
<template>
<div>
<div
v-for="(data,index) in projectDetailsJson" v-if="index <= 1">
<h1>{{ data.title }}</h1>
<p>{{ data.description }}</p>
</div>
</div>
</template>
<script>
import json from '#/json/projectDetails.json'
export default {
name: 'projectDetails',
data(){
return{
projectDetailsJson: json
}
},
props: {
description: String,
title: String
}
}
</script>
I am successfully routing to the URL I want, which is /project/'name'. I want to use the projectDetails component as the framework for each of my individual project pages. But how do I do this dynamically? I want to retrieve data from a JSON file and display the correct object from the array based on the name that was passed to the URL. I do not want to iterate and have all of the array display on the page. I just want one project to display.
Quick solution:
projectDetails.vue
<template>
<div>
<div>
<h1>{{ projectDetails.title }}</h1>
<p>{{ projectDetails.description }}</p>
</div>
</div>
</template>
<script>
import json from '#/json/projectDetails.json';
export default {
name: 'projectDetails',
props: {
name: String,
},
data() {
return {
projectDetails: Object.values(json).find(project => project.title === this.name),
};
},
};
</script>
In my opinion, a better solution:
I don't get the idea that you keep project data in 2 separate JSON files. During compilation, both files are saved to the resulting JavaScript file. Isn't it better to keep this data in 1 file? You don't have to use all of your data in one place. The second thing, if you have a project listing then you can do routing with an optional segment, and depending on whether the segment has a value or not, display the listing or data of a particular project. Then you load project data only in one place, and when one project is selected, pass its data to the data rendering component of this project. Nowhere else do you need to load this JSON file.
routes.js
import home from '#/components/home.vue';
import about from '#/components/about.vue';
import work from '#/components/work.vue';
const routes = [
{path: '/', name: 'home', component: home},
{path: '/about', name: 'about', component: about},
{path: '/work/:name?', name: 'work', component: work, props: true},
];
export default routes;
work.vue
<template>
<div>
<project-details v-if="currentProject" :project="currentProject"/>
<projectLink v-else
v-for="project in projects"
v-bind="project"
v-bind:key="project.projectName"
/>
</div>
</template>
<script>
import projectLink from './projectLink';
import projectDetails from './projectDetails';
import json from '#/json/projectLink.json';
export default {
name: 'work',
props: {
name: String,
},
data() {
return {
projects: Object.values(json),
};
},
computed: {
currentProject() {
if (this.name) {
return this.projects.find(
project => project.projectName === this.name,
);
}
},
},
components: {
projectLink,
projectDetails,
},
};
</script>
projectDetails.vue
<template>
<div>
<div>
<h1>{{ project.title }}</h1>
<p>{{ project.description }}</p>
</div>
</div>
</template>
<script>
export default {
name: 'projectDetails',
props: {
project: Object,
},
};
</script>
projectLink.vue (changed only one line)
<router-link v-if="projectName" :to="{ name: 'work', params: { name: projectName }}">

Great work thus far, Austin! You're very close having this working. There are a few different ways you could parse out the correct data from your JSON file into the projectDetails component, but I'll just demo my preferred way.
First, you're going to need a bit of vanilla JS to search through your JSON file and return only the row that you want. I would do this as a method since the data isn't going to be changing or requiring the component to re-render. So, after your props, I would add something like this:
methods: {
findProject(projectName) {
return Object.values(json).find(project => project.title === projectName)
}
}
Note that this is going to return the first project that matches the project name. If you have projects with the exact same project name, this won't work.
Next, you'll just need to update the default value of projectDetailsJson to call this method and pass the route's project name. Update data with something like this:
data() {
return {
projectDetailsJson: this.findProject(this.$route.params.name)
}
}
If that doesn't work, we may need to set the projectDetailsJson in the created lifecycle hook, but try the above code first.
If I understood correctly, you want to keep a parent component as a layout for all of your page?
If I always understood correctly, you must use the children property of vuerouter
https://router.vuejs.org/guide/essentials/nested-routes.html
import layout from 'layout';
const projectRoute = {
path: '/project',
component: Layout, // Load your layout
redirect: '/project/list',
name: 'Project',
children: [
{
path: "list", // here the path become /project/list
component: () => import('#/views/project/List'), // load your components
name: "List of project",
},
{
path: "detail/:id",
component: () => import('#/views/project/Detail'),
name: "Detail of project",
}
],
};
So you can create your layout and add everything you want, this will be available on all child components, and you can use $emit, $refs $props ect...
+
You can create an file routes/index.js and create folder routes/modules . Inside this, you can add your routes/modules/project.js and load the modules in routes/index.js
import Vue from 'vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);
import projectRoutes from "./modules/project";
const routes = [
projectRoutes,
{
// other routes....
},
]
export default new VueRouter({
routes,
mode: 'history',
history: true,
});
#see the same doc : https://router.vuejs.org/guide/essentials/nested-routes.html
Finally, you just have to do the processing on the layout, and use the props to distribute the values both in detail and in the project list; and use the filter methods described just above
I hope I have understood your request, if this is not the case, let me know,
see you
Edit: Here is a very nice architecture with vue, vuex and vuerouter. maybe inspire you
https://github.com/tuandm/laravue/tree/master/resources/js
For everyone, to take this one step further. How would you show only the projectLinks that match the current URL? So if I have three different JSON projectTypes: design, code, motion. If the URL contains motion in it, how do I filter my projectLink components to show only those that have a matching JSON value of either design, code or motion. Essentially I'm just trying to filter.
I'm trying to include a local JSON file from the static directory called blogs.json which has a load of blogs inside it.
I'm currently loading the blogs via Vue Axios which is a module I'm including in Nuxt JS.
Currently, the blogs are being loaded from the json file perfectly fine, however there is a noticeable few ms delay before the blogs are loaded, I'm trying to figure out a better approach to load the json file and populate the blogs array listed inside data()
This is my current code:
<script>
import PageBanner from '~/components/PageBanner';
export default {
head: {
title: 'Site Title: Blog',
meta: [
{ hid: 'description', name: 'description', content: 'Site description' }
]
},
components: {
PageBanner
},
data () {
return {
blogs: [],
isLoading: true
}
},
created () {
this.axios.get("/articles/blogs.json").then((response) => {
this.blogs = response.data
this.isLoading = false
})
}
}
</script>
This works just fine, but how could I modify this to load the json more quickly?
Just import it, do this and it should work God willing:
<template>
<div>
<!-- There should be no delay -->
{{blogs}}
</div>
<template>
<script>
import PageBanner from '~/components/PageBanner';
import blogsFromJson from '~/articles/blogs.json'; // Or wherever it is found
export default {
head: {
title: 'Site Title: Blog',
meta: [
{ hid: 'description', name: 'description', content: 'Site description' }
]
},
components: {
PageBanner
},
data () {
return {
blogs: blogsFromJson, // Just set it here
isLoading: true
}
},
/* No need for this anymore
created () {
this.axios.get("/articles/blogs.json").then((response) => {
this.blogs = response.data
this.isLoading = false
})
}
*/
}
</script>
I am making a vue app. I put a .json file in static directory. I am trying to read it in the default HelloWorld.vue file. But it's not showing in the browser. Here is what it shows in the browser:
My json file looks like this:
{
"status": "success",
"message": "Successfully retrieved all registered applications",
"Applications": [
{
"ApplicationID": "74382DOD",
"ApplicationName": "OIMInstance2",
"ApplicationType": "OIM",
"APIToken": "ZM8R4FRiZWWKbl235u06zbArCdOBPlEKhqHQO8Y9RJ2HgBPC+cZgbIli8fFuNZaey/2tJciJuILIWIn24WTjGA=="
},
{
"ApplicationID": "943ODA6G",
"ApplicationName": "LDAPInstance2",
"ApplicationType": "LDAP",
"APIToken": "R9lDEW5dnN6TZg2sefEEzS6LWMNmFh4iLHMu47LmAsusHl0bZuh2rktSlXqSZRdHHEWq7sP4Xsdy6xNtDYE8xw=="
}
]
}
My code in HelloWorld.vue is:
<template>
<div>
<h1>APPLICATION REGISTRATION</h1>
<div v-for="udata in userData">
Id : {{ udata.ApplicationID }}
</div>
</div>
</template>
<script>
import Vue from 'vue'
import axios from 'axios'
import VueAxios from 'vue-axios'
Vue.use(VueAxios, axios)
export default {
name: 'HelloWorld',
data () {
return {
userData: []
}
},
created: function() {
axios.get('../../static/mockdata.json')
.then(response => {
this.userData = response.data
})
.catch(e => {
//this.errors.push(e)
})
}
}
</script>
Is there anything wrong with my code? How do I show the json data in the browser?
You need to iterate through applications object.Hence in order to get applicationId you will need to set data accordingly by only adding applications data in your userData variable.
Do as below.
this.userData = response.data.Applications
I have a json file named autofill.json and it's created to autofill a search bar when pressed on.
the autofill.json is a test file that's why it looks like this.
[
{
"a": {
"apple": {
"name": "apple",
"href": "https://www.apple.com/"
},
"armadillo": {
"name": "armadillo",
"href": "https://www.armadillo.com/"
}
},
"b": {
"box": {
"name": "apple",
"href": "https://www.berserk.com/"
},
"berserk": {
"name": "berserk",
"href": "https://www.berserk.com/"
}
}
}
]
The .json file is then fetched in the file named FetchAndParseResults.js
import fetch from 'isomorphic-fetch'
const FetchAndParseResults = (url) => {
return fetch(url).then(response => {
const parsedJson = response.json()
return parsedJson
})
}
export default FetchAndParseResults
The data that gets fetched is used in searchcontainer.js where everything gets placed in, the search etc.
import React from 'react'
import Searchbar from './index.js'
import FetchAndParseResults from './FetchAndParseResults.js'
class SearchContainer extends React.Component {
state = {
results: []
}
performSearch = event => {
return FetchAndParseResults('static/autofill.json').then(data => {
this.setState({ results: data })
})
}
render () {
console.log('performSearch event', this.performSearch)
console.log('data inside performSearch', this.state.results)
return (
<Searchbar
performSearch={this.performSearch}
results={this.state.results}
/>
)
}
}
export default SearchContainer
Then to map through the data that is in autofill.json there is a file named autofill.js
import React from 'react'
import PropTypes from 'prop-types'
import Styles from './searchbar.scss'
const AutoFill = (props) => {
console.log('proppppppsss', props)
const results = props.results || []
return (
<ul className={Styles.searchUl}>
{results.map(({ name, href }) => (
<li className={Styles.searchLi} key={href}>
<a className={Styles.searchA} href={href} target='_blank' rel='noopener noreferrer' key={href}>
{name}
</a>
</li>
))}
</ul>
)
}
AutoFill.propTypes = {
results: PropTypes.array
}
export default AutoFill
the Searchbar component in (index.js) that is being used in searchcontainer.js
import React from 'react'
import Styles from './searchbar.scss'
import Icon from '../../components/icon/icon'
import Search from '../../components/form-input/search'
import AutoFill from './autofill'
import PropTypes from 'prop-types'
export default class Searchbar extends React.Component {
constructor (props) {
super(props)
this.state = {
className: Styles.input,
icon: Styles.icon__wrapper,
value: []
}
this.input = React.createRef()
}
openInput = () => {
this.setState({
className: Styles.input__active,
icon: Styles.iconWidth
}, () => {
this.input.focus()
})
this.props.onOpen && this.props.onOpen()
}
closeInput = () => {
this.setState({
className: Styles.input,
icon: Styles.icon__wrapper
})
this.props.onClose && this.props.onClose()
}
handleChange = event => {
let value = event.target.value
this.setState({ value })
this.props.performSearch(value)
}
handleSubmit = event => {
event.preventDefault()
}
render () {
console.log('results', this.props.results)
console.log('state.value', this.state.value)
return (
<div>
<form onSubmit={this.handleSubmit} className={Styles.search}>
<div className={this.state.icon}>
<Icon className={Styles.icon__wrapper} iconName='faSearch' onClick={this.openInput} />
</div>
<Search autoComplete='off' value={this.state.value} onChange={this.handleChange} id='search' tabIndex='0' myref={input => { this.input = input }} className={this.state.className} onBlur={this.closeInput} placeholder='Search' />
</form>
<div>
<AutoFill results={this.props.results} />
</div>
</div>
)
}
}
Search.propTypes = {
performSearch: PropTypes.func,
results: PropTypes.array
}
When i try to refer to a what is in the json file from the search i receive the error,
GET http://localhost:3000/[object%20Object] 404 (Not Found)
And
about:1 Uncaught (in promise) SyntaxError: Unexpected token < in JSON
at position 0
The second error is fixed by doing
const parsedJson = response.text(
instead of
const parsedJson = response.json()
to get more information where/what the error takes place. But by doing this i receive the error,
searchcontainer.js:12 Uncaught (in promise) TypeError: Cannot read property 'results' of undefined
I've tried to run it from npm build instead of running it in a dev environment which didn't fix it.
I read that a mock url should work but then again i want to acces it from a file and not from a url?
Any help would be highly appreciated and looked into.
The problem is most likely in the fetch call. If you look at the error message GET http://localhost:3000/[object%20Object] 404 (Not Found)
You can see that it is trying to append an object to the URL localhost:3000/.
You are getting the Unexpected token < in JSON at position 0 error because the response of your fetch request is probably a 404 page. The < is most likely the first char of <html>
To access the JSON object in your React files, you can simply do an importation like so;
import * as autofillData from 'autofill.json';
It will be returned as a JSON object.
I believe you are using the isomorphic-fetch package wrongly, if you look at their source code, https://github.com/matthew-andrews/isomorphic-fetch/blob/master/fetch-npm-node.js#L5 , they are accepting a URL to make a call to the API URL which will return a promise or a JSON object depending on the implementation of the API that you are calling.
If you were to dive deeper into the open-source code here (https://github.com/matthew-andrews/isomorphic-fetch/blob/master/fetch-npm-node.js#L8) , you will notice that isomorphic-fetch package is using another package node-fetch to do their fetch call, which accepts the API URL and the method request options to call the API with. (As stated here; https://github.com/bitinn/node-fetch/blob/master/src/index.js#L34)
To continue with your test, perhaps this might be the solution you'd prefer?
import fetch from 'isomorphic-fetch';
import * as autofillData from 'autofill.json'; //test data
const FetchResults = event => {
return fetch('/https://jsonplaceholder.typicode.com/todos/1'') //mockURL, to be replaced with real API
.then(response => {
// const parsedJson = response.json(); // TODO: un-comment this line when the real API url is usable
const parsedJson = autofillData; // TODO: remove this line when mocking is done and the real API URL is ready
return parsedJson;
})
}
export default FetchResults;
To have a mock URL placeholder, I would suggest https://jsonplaceholder.typicode.com/ to prevent your fetch result to return an unexpected error during test mocking.
Hope this is helpful.
The question has been solved, The main issue was with defining const names such as const results = [] which should've been const results = props.results || [].
The code has been updated incase you have problems aswell.
So I'm trying to create a VueJS application, and I was given a set of JSON objects that are retrievable through a .json endpoint.
I'll call them People. So I get an array of people in this.people after using VueResource.
I'm able to iterate and get all the name displayed on the side, however, since its not an API nor has unique IDs minus their array indexes, I am having trouble trying to narrow down each object and create a single Person view page.
Hence if it was a normal api, I could do '/people/:id', but I can't. I'm also wondering if I may have stored the Prop/Component correctly.
I put together a quick example of how this might work with the Star Wars API.
const Loading = {
template: `<h1>Loading...</h1>`
};
const People = {
props: ["people"],
template: `
<div>
<h1>People</h1>
<ul>
<li v-for="person in people">
<router-link :to='{name: "person", params:{person: person}}'>{{person.name}}</router-link>
</li>
</ul>
</div>
`
};
const PersonDetails = {
props: ["person"],
template: `
<div>
<h1>{{person.name}}</h1>
<div>Height: {{person.height}}</div>
<div>Mass: {{person.mass}}</div>
<div>Hair Color: {{person.hair_color}}</div>
<br/>
<router-link to="people">Back to people</router-link>
</div>
`
};
const routes = [
{ path:"/", component: Loading},
{ path: "/people", name: "people", component: People},
{ path: "/person", name: "person", component: PersonDetails, props: true},
]
const router = new VueRouter({
routes
})
new Vue({
el: "#app",
router,
data:{
people:[]
},
mounted(){
this.$axios.get("https://swapi.co/api/people/")
.then((response) => {
this.people = response.data.results
this.$router.push("people")
})
}
});
Here is the working example.
