A Visual Flow Editor Based on Vue And Antv/g6

Introduction

vue-visual-flowIt is based on antv/g6the configuration of the visualization routine implemented Vuecomponents

Project uses rolluppackaged, are provided cjs esmin two modular form to introduce ways, size is only about 100K

Design ideas

In order to remove the business logic as much as possible, the component shares the G6 instance, as well as the currently operating node and edge instance, for users to complete their own business logic externally

About G6 api: G6

Part of the problem and progress tracking

Currently antv/g6there will be an updated version of the problem after the disappearance of custom graphics, it does not support the new antv/g6tracking Issue: G6-Issue

issue has been fixed, use antv/g6@3.7.3and above

Currently does not support simultaneous node configuration settings tipsand anchor configuration labelNamecauses a problem can not be switched prompt information g6-issue

issue has been fixed, use antv/g6@3.8.1and above

8 Popular Websites That Use The Vue.JS Framework

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.

Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.

This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.

Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.

Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.

“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You

Vue File Upload Using vue-dropzone Tutorial

In this tutorial, I will show you how to upload a file in Vue using vue-dropzone library. For this example, I am using Vue.js 3.0. First, we will install the Vue.js using Vue CLI, and then we install the vue-dropzone library. Then configure it, and we are ready to accept the file. DropzoneJS is an open source library that provides drag and drops file uploads with image previews. DropzoneJS is lightweight doesn’t depend on any other library (like jQuery) and is highly customizable. The vue-dropzone is a vue component implemented on top of Dropzone.js. Let us start Vue File Upload Using vue-dropzone Tutorial.

Dropzone.js is an open-source library providing drag-and-drop file uploads with image previews. DropzoneJS is lightweight, doesn’t depend on any other library (like jQuery), and is highly customizable.

The vue-dropzone is a vue component implemented on top of Dropzone.js.

First, install the Vue using Vue CLI.

Step 1: Install Vue.js using Vue CLI.

Go to your terminal and hit the following command.

npm install -g @vue/cli
         or
yarn global add @vue/cli

If you face any error, try running the command as an administrator.

Now, we need to generate the necessary scaffold. So type the following command.

vue create vuedropzone

It will install the scaffold.

Open the project in your favorite editor. Mine is Visual Studio Code.

cd vuedropzone
code .

Step 2: Install vue-dropzone.

I am using the Yarn package manager. So let’s install using Yarn. You can use NPM, also. It does not matter.

yarn add vue2-dropzone

or

npm install vue2-dropzone

Okay, now we need to add one css file with the above package. Now, vue cli uses css loader, so we can directly import in the src >> main.js entry file.

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

new Vue({
  render: h => h(App)
}).$mount('#app')

import 'vue2-dropzone/dist/vue2Dropzone.css'

If importing css is not working for you, then you need to install that CSS file manually.

Copy this vue2Dropzone.css file’s content.

Create one file inside the src >> assets folder, create one css file called vuedropzone.css and paste the content there.

Import this css file inside src >> App.vue file.

<style lang="css">
  @import './assets/vuedropzone.css';
</style>

Now, it should include in our application.

Step 3: Upload an Image.

Our primary boilerplate has one ready-made component called HelloWorld.vue inside src >> components folder. Now, create one more file called FileUpload.vue.

Add the following code to FileUpload.vue file.

// FileUpload.vue

<template>
  <div id="app">
    <vue-dropzone id="upload" :options="config"></vue-dropzone>
  </div>
</template>

<script>
import vueDropzone from "vue2-dropzone";

export default {
  data: () => ({
    config: {
      url: "https://appdividend.com"
    }
  }),
  components: {
    vueDropzone
  }
};
</script>

Here, our API endpoint is https://appdividend.com. It is the point where we will hit the POST route and store our image, but it is my blog’s homepage, so it will not work anyway. But let me import this file into App.vue component and see what happens.

// App.vue

<template>
  <div id="app">
    <FileUpload />
  </div>
</template>

<script>
import FileUpload from './components/FileUpload.vue'

export default {
  name: 'app',
  components: {
    FileUpload
  }
}
</script>

<style lang="css">
  @import './assets/vuedropzone.css';
</style>

Now, start the development server using the following command. It will open up URL: http://localhost:8080.

npm run serve

Now, after uploading the image, we can see that the image upload is failed due to the wrong POST request endpoint.

Step 4: Create Laravel API for the endpoint.

Install the Laravel.

After that, we configure the database in the .env file and use MySQL database.

We need to create one model and migration file to store the image. So let us install the following command inside the Laravel project.

php artisan make:model Image -m

It will create both the Image model and create_images_table.php migrations file.

Now, open the migrations file and add the schema to it.

// create_images_table.php

public function up()
    {
        Schema::create('images', function (Blueprint $table) {
            $table->increments('id');
            $table->string('image_name');
            $table->timestamps();
        });
    }

Now, migrate the database table using the following command.

php artisan migrate

It creates the table in the database.

Now, we need to add a laravel-cors package to prevent cross-site-allow-origin errors. Go to the Laravel root and enter the following command to install it.

composer require barryvdh/laravel-cors

Configure it in the config >> app.php file.

Barryvdh\Cors\ServiceProvider::class,

Add the middleware inside app >> Http >> Kernel.php file.

// Kernel.php

protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\TrustProxies::class,
        \Barryvdh\Cors\HandleCors::class,
];

Step 5: Define the API route and method to store the image.

First, create an ImageController.php file using the following command.

php artisan make:controller ImageController

Define the store method. Also, create one images folder inside the public directory because we will store an image inside it.

Right now, I have written the store function that handles one image at a time. So do not upload multiple photos at a time; otherwise, it will break.

// ImageController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Image;

class ImageController extends Controller
{
    public function store(Request $request)
    {
       if($request->file('file'))
       {
          $image = $request->file('file');
          $name = time().$image->getClientOriginalName();
          $image->move(public_path().'/images/', $name); 
        }

       $image= new Image();
       $image->image_name = $name;
       $image->save();

       return response()->json(['success' => 'You have successfully uploaded an image'], 200);
     }
}

Go to the routes >> api.php file and add the following route.

// api.php

Route::post('image', 'ImageController@store');

Step 6: Edit FileUpload.vue component.

We need to add the correct Post request API endpoint in FileUpload.vue component.

// FileUpload.vue

<template>
  <div id="app">
    <vue-dropzone id="drop1" :options="config" @vdropzone-complete="afterComplete"></vue-dropzone>
  </div>
</template>

<script>
import vueDropzone from "vue2-dropzone";

export default {
  data: () => ({
    config: {
      url: "http://localhost:8000/api/image",
      
    }
  }),
  components: {
    vueDropzone
  },
  methods: {
    afterComplete(file) {
      console.log(file);
    }
  }
};
</script>

Now, save the file and try to upload an image. If everything is okay, then you will be able to save the image on the Laravel web server as well as save the name in the database as well.

You can also verify on the server side by checking the database entry and the images folder in which we have saved the image.

Step 7: More vue-dropzone configuration.

The only required options are url, but there are many more you can use.

For example, let’s say you want:

A maximum of 4 files
2 MB max file size
Sent in chunks of 500 bytes
Set a custom thumbnail size of 150px
Make the uploaded items cancelable and removable (by default, they’re not)

export default {
  data: () => ({
    dropOptions: {
      url: "https://httpbin.org/post",
      maxFilesize: 5, // MB
      maxFiles: 5,
      chunking: true,
      chunkSize: 400, // Bytes
      thumbnailWidth: 100, // px
      thumbnailHeight: 100,
      addRemoveLinks: true
    }
  })
  // ...
}

Happy Coding !!!
