如何将mxGraph与Angular 4集成? [英] How to integrate mxGraph with Angular 4?

问题描述

我正在使用Angular 4，并且希望将mxGraph集成到我的项目中. 我已经用谷歌搜索了，但是我没有完整的示例.

I am working on Angular 4 and I want to integrate mxGraph in my project. I have googled for it but I am not getting the full working example.

我尝试过以下方法，但对我也不起作用.

I have tried following way, but it also not working for me.

我遵循的步骤:

1. 已安装的mxgraph:npm install mxgraph --save

用于mxgraph的npm软件包: https://www.npmjs.com/package/mxgraph

npm package for mxgraph: https://www.npmjs.com/package/mxgraph

已安装的mxgraph类型:npm install lgleim/mxgraph-typings --save

Installed mxgraph-typings: npm install lgleim/mxgraph-typings --save

mxgraph-typings的Github回购- https://github.com/lgleim/mxgraph-typings

Github Repo of mxgraph-typings - https://github.com/lgleim/mxgraph-typings

现在我已将其导入到组件中:import {mxgraph} from 'mxgraph';

Now I have imported it in my component: import {mxgraph} from 'mxgraph';

在.angular-cli.json资产数组中添加了以下行，以使mxGraph资产可用.

Added the following line in .angular-cli.json assets array to make the mxGraph assets available.

{"glob":"**/*", "input":"node_modules/mxgraph/javascript/src", "output": "./mxgraph"}

如果我尝试使用它，例如:const graph: mxgraph.mxGraph = new mxgraph.mxGraph(document.getElementById('graphContainer'));

当我运行ng serve

然后我遇到问题/错误，例如:
Module not found: Error: Can't resolve 'mxgraph' in 'path to my file where I have imported and used mxgraph'

Then I get issue/error like:
Module not found: Error: Can't resolve 'mxgraph' in 'path to my file where I have imported and used mxgraph'

现在，如果我尝试设置mxBasePath:

Now if I try with setting mxBasePath:

const mx = require('mxgraph')({
  mxImageBasePath: 'mxgraph/images',
  mxBasePath: 'mxgraph'
});

并以此方式使用:

const graph: mxgraph.mxGraph = mx.mxGraph(document.getElementById('graphContainer'));

当我运行ng serve

这一次我也遇到同样的问题/错误:
Module not found: Error: Can't resolve 'mxgraph' in 'path to my file where I have imported and used mxgraph'

This time also I am getting same issue/error:
Module not found: Error: Can't resolve 'mxgraph' in 'path to my file where I have imported and used mxgraph'

有人对我在这里想念的东西有任何想法吗?还是为什么不起作用?

Is anyone have any idea of what I am missing here? Or Why is it not working?

如果有人知道将mxGraph与Angular 4集成的任何其他/更好的方式，请告诉我.

If someone knows any other/better way of integrating mxGraph with Angular 4, then please let me know.

预先感谢！

推荐答案

如果仍然有人在Angular 4/5/6中与mxGraph集成苦苦挣扎.然后是完整的解决方案:

If anyone still struggling with mxGraph integration in Angular 4/5/6. Then here is Complete Solution:

有关不同的mxGraph存储库的一些详细信息:

Few details about different mxGraph Repos:

Repo-1: https://github.com/jgraph/mxgraph
        This is an official release repo of mxGraph. With npm issues.

Repo-2: https://bitbucket.org/jgraph/mxgraph2
        This is an official development repo of mxGraph. With npm issues.

If anyone wants to see what npm issues with these above repos(i.e. Repo-1 and Repo-2), then check these following issues:  
            - https://github.com/jgraph/mxgraph/issues/169
            - https://github.com/jgraph/mxgraph/issues/175

Repo-3: https://bitbucket.org/lgleim/mxgraph2
        Fork of Repo-2. With npm fixes.

Repo-4: https://github.com/ViksYelapale/mxgraph2
        Fork of Repo-2. Merged npm fixes from Repo-3 as well. Added changes(i.e. required for local installation of mxGraph) to this repo.

步骤:

1. 克隆Repo-4.另外，添加官方回购协议(即Repo-2)的远程版本，以获取最新的mxGraph更新/发行版/修复程序.

1. Clone Repo-4. Also, add remote of the official repo(i.e. Repo-2) to take the latest mxGraph updates/release/fixes.

将目录更改为mxgraph2并运行npm install

Change directory to the mxgraph2 and run npm install

$ cd mxgraph2
$ npm install

$ cd mxgraph2
$ npm install

现在转到您的角度项目存储库并安装mxGraph(即我们在本地构建的mxgraph2).

Now go to your angular project repo and install mxGraph(i.e. mxgraph2 which we have build locally).

$ npm install /path/to/mxgraph2

例如npm install /home/user/workspace/mxgraph2

这将在package.json文件中添加如下所示的类似条目:

Which will add a similar entry as below in your package.json file:

"mxgraph": "file:../mxgraph2"

运行一次正常的npm安装.用于添加任何缺少/依赖的程序包.

Run normal npm install once. For adding any missing/dependency package.

$ npm install

现在我们将安装mxgraph类型

Now we will install mxgraph typings

注意-打字稿的最低要求为2.4.0

Note - Minimum required version of the typescript is 2.4.0

$ npm install lgleim/mxgraph-typings --save

现在您可以在应用程序中使用mxGraph.

Now you can use mxGraph in your app.

i. component.ts

i. component.ts

import { mxgraph } from "mxgraph";

declare var require: any;

const mx = require('mxgraph')({
  mxImageBasePath: 'assets/mxgraph/images',
  mxBasePath: 'assets/mxgraph'
});

.
.
.

ngOnInit() {
   // Note - All mxGraph methods accessible using mx.xyz
   // Eg. mx.mxGraph, mx.mxClient, mx.mxKeyHandler, mx.mxUtils and so on.

   // Create graph

   var container = document.getElementById('graphContainer');
   var graph = new mx.mxGraph(container);

   // You can try demo code given in official doc with above changes.
}

ii. component.html

ii. component.html

<div id="graphContainer"></div>

就是这样！

希望这会有所帮助.
