如何将 mxGraph 与 Angular 4 集成?

问题描述

我正在研究 Angular 4，我想将 mxGraph 集成到我的项目中.我用谷歌搜索过，但没有得到完整的工作示例.

我尝试了以下方法，但它也不适合我.

我遵循的步骤:

1. 安装mxgraph:npm install mxgraph --save

   mxgraph 的 npm 包:https://www.npmjs.com/package/mxgraph

2. 安装的 mxgraph-typings:npm install lgleim/mxgraph-typings --save

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

3. 现在我已经将它导入到我的组件中:import {mxgraph} from 'mxgraph';

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

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

5. 如果我尝试像这样使用它:const graph: mxgraph.mxGraph = new mxgraph.mxGraph(document.getElementById('graphContainer'));

   当我运行 ng serve

   然后我得到如下问题/错误:
   未找到模块:错误:无法解析我已导入并使用 mxgraph 的文件的路径"中的mxgraph"

6. 现在，如果我尝试设置 mxBasePath:

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

   并像这样使用:

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

   当我运行 ng serve

   这次我也遇到了同样的问题/错误:
   未找到模块:错误:无法解析我已导入并使用 mxgraph 的文件的路径"中的mxgraph"

有人知道我在这里遗漏了什么吗?或者为什么它不起作用?

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

提前致谢！！

解决方案

如果有人还在为 Angular 4/5/6 中的 mxGraph 集成而苦苦挣扎.然后这里是完整的解决方案:

关于不同 mxGraph Repos 的一些细节:

Repo-1: https://github.com/jgraph/mxgraph这是 mxGraph 的官方版本存储库.与 npm 问题.回购 2:https://bitbucket.org/jgraph/mxgraph2这是 mxGraph 的官方开发库.与 npm 问题.如果有人想查看上述这些 repos(即 Repo-1 和 Repo-2)的 npm 问题，请检查以下问题:- https://github.com/jgraph/mxgraph/issues/169- https://github.com/jgraph/mxgraph/issues/175Repo-3:https://bitbucket.org/lgleim/mxgraph2Repo-2 的分叉.使用 npm 修复.Repo-4:https://github.com/ViksYelapale/mxgraph2Repo-2 的分叉.也从 Repo-3 合并了 npm 修复.向此存储库添加了更改(即本地安装 mxGraph 所需).

步骤:

1. 克隆 Repo-4.此外，添加远程官方仓库(即 Repo-2)以获取最新的 mxGraph 更新/发布/修复.

2. 将目录切换到 mxgraph2 并运行 npm install

   $ cd mxgraph2
$ npm install

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

   $ npm install/path/to/mxgraph2

   例如npm install/home/user/workspace/mxgraph2

   这将在您的 package.json 文件中添加如下类似的条目:

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

4. 运行一次普通的 npm install.用于添加任何缺失/依赖包.

   $ npm install

5. 现在我们将安装 mxgraph 类型

   注意 - 所需的打字稿最低版本为 2.4.0

   $ npm install lgleim/mxgraph-typings --save

6. 现在您可以在您的应用中使用 mxGraph.

   我.组件.ts

   import { mxgraph } from "mxgraph";声明 var 要求:任何；const mx = require('mxgraph')({mxImageBasePath: 'assets/mxgraph/images',mxBasePath: '资产/mxgraph'});...ngOnInit() {//注意 - 使用 mx.xyz 可访问的所有 mxGraph 方法//例如.mx.mxGraph、mx.mxClient、mx.mxKeyHandler、mx.mxUtils 等.//创建图形var container = document.getElementById('graphContainer');var graph = new mx.mxGraph(container);//您可以尝试使用官方文档中给出的演示代码进行上述更改.}

   二.组件.html

7. 就是这样！！

希望能帮到你.

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.

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

Steps I have followed:

1. Installed mxgraph: npm install mxgraph --save

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

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

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

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

4. 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"}
   

5. If I try to use it like: const graph: mxgraph.mxGraph = new mxgraph.mxGraph(document.getElementById('graphContainer'));

   And when I run ng serve

   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'

6. Now if I try with setting mxBasePath:

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

   And used like this:

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

   And when I run ng serve

   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'

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

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

Thanks in Advance !!

解决方案

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

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.

Steps:

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

2. Change directory to the mxgraph2 and run npm install

   $ cd mxgraph2
$ npm install

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

   $ npm install /path/to/mxgraph2

   e.g. npm install /home/user/workspace/mxgraph2

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

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

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

   $ npm install

5. Now we will install mxgraph typings

   Note - Minimum required version of the typescript is 2.4.0

   $ npm install lgleim/mxgraph-typings --save

6. Now you can use mxGraph in your app.

   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

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

7. That's it !!
