## Integrate DevExtreme Packages to ABP Framework Based Applications
Hi, in this step-by-step article, I will show you how to integrate DevExtreme components into ABP Framework based applications.
## Install DevExtreme
You can follow [this documentation](https://js.devexpress.com/Documentation/17_1/Guide/ASP.NET_MVC_Controls/Prerequisites_and_Installation/) to install devexpress packages.
## Preparing the Project
### Startup template and the initial run
Abp Framework offers startup templates to get into the business faster. We can download a new startup template using Abp CLI:
`abp new DevExtremeSample -m none`
After the download is finished, we run `DevExtremeSample.DbMigrator` project to create the database and seed initial data (admin user, role, etc). Then we run `DevExtremeSample.Web` to see our application working.
> _Default admin username is **admin** and password is **1q2w3E\***_
![initial-project](initial-project.png)
### Adding DevExtreme Nuget Packages
Add following `PackageReference` to your `DevExtremeSample.Application.Contracts` project.
`<PackageReference Include="DevExtreme.AspNet.Core" Version="20.1.6" />`
Add following `PackageReference` to your `DevExtremeSample.Application.Web` project.
`<PackageReference Include="DevExtreme.AspNet.Data" Version="2.6.2" />`
> Please remember that, you must add _"DevExpress NuGet Feed"_ to your **Nuget Package Sources**. Check [this documentation](https://js.devexpress.com/Documentation/17_1/Guide/ASP.NET_MVC_Controls/Prerequisites_and_Installation/) to more information.
After adding new packages, do `dotnet restore` for your projects.
### Adding DevExtreme NPM Packages
Open `package.json` file in your `DevExtremeSample.Application.Web` project and add following package depency to `depencies` section.
`"devextreme": "^20.1.5"`
Then just open `DevExtremeSample.Application.Web` project folder via CLI and run `yarn` command.
This will add the DevExtreme npm packages to our node_modules folder as seen below.
![yarn](yarn.png)
We should add some mappings to move required files to under `wwwroot/libs` folder.
Open `abp.resourcemapping.js` file in your `DevExtremeSample.Application.Web` project and replace the content of file with following.
```javascript
module.exports = {
aliases: {},
mappings: {
"@node_modules/devextreme/dist/**/*": "@libs/devextreme/",
},
};
```
Open `DevExtremeSample.Application.Web` project folder via CLI and run `gulp` command. This action will do mappings as we described before.
![gulp](gulp.png)
You can see `devextreme` folder in your `wwwroot/libs` folder.
![wwwroot-lib](wwwroot-lib.png)
### Adding DevExtreme Css Files To Global Bundles
Open your `DevExtremeSampleWebModule.cs` file in your `DevExtremeSample.Application.Web` project and add following code to `ConfigureServices` method.
```csharp
Configure<AbpBundlingOptions>(options =>
{
options
.StyleBundles
.Get(StandardBundles.Styles.Global)
.AddFiles("/libs/devextreme/css/dx.common.css")
.AddFiles("/libs/devextreme/css/dx.light.css");
});
```
### Adding DevExtreme Js Files
We cannot add DevExtreme js packages to `Global Script Bundles`, because DevExtreme js packages requires to located in the `<head>` section.
But we can create `ViewComponent` and render it at `<head>` section with `AbpLayoutHookOptions`.
Create `Components` folder in your `DevExtremeSample.Application.Web` project. Then create `DevExtremeJs` folder under `Components` folder.
Create `Default.cshtml` file in your `DevExtremeJs` folder and paste following codes to your file.
```csharp
@addTagHelper *, Volo.Abp.AspNetCore.Mvc.UI.Bundling
<!-- Devextreme -->
<abp-script src="/libs/devextreme/js/dx.all.js" />
<abp-script src="/libs/devextreme/js/dx.aspnet.mvc.js" />
<abp-script src="/libs/devextreme/js/dx.aspnet.data.js" />
```
Create `DevExtremeJsViewComponent.cs` file in your `DevExtremeJs` folder and paste following codes to your file.
```csharp
namespace DevExtremeSample.Web.Components.DevExtremeJs
{
public class DevExtremeJsViewComponent : AbpViewComponent
{
public IViewComponentResult Invoke()
{
return View("/Components/DevExtremeJs/Default.cshtml");
}
}
}
```
After that, your `*.Web` project should be like as following.
![devextreme-js](devextreme-js.png)
Then we can add this view component to `<head>` section by using **hooks**.
Open your `DevExtremeSampleWebModule.cs` file in your `DevExtremeSample.Application.Web` project and add following code to `ConfigureServices` method.
```csharp
Configure<AbpLayoutHookOptions>(options =>
{
options.Add(
LayoutHooks.Head.Last, //The hook name
typeof(DevExtremeJsViewComponent) //The component to add
);
});
```
### Manipulate `JQueryScriptContributor`
In ABP Framework, all javascript files are located at the end of file by default. But DevExtreme is using `inline` javascript codes and those are requires the `jQuery` package located at `<head>` section.
ABP Framework has a one contributor that named `JQueryScriptContributor` for `jQuery` packages. It has `jQuery` and some abp packages. We need to manipulate that.
So create `jQuery` folder in `Components` folder at your `*.Web` project.
Create `Default.cshtml` file in your `jQuery` folder and paste following codes to your file.
```csharp
@addTagHelper *, Volo.Abp.AspNetCore.Mvc.UI.Bundling
<script src="/libs/jquery/jquery.js"></script>
```
Create `JqueryHeadViewComponent.cs` file in your `jQuery` folder and paste following codes to your file.
```csharp
using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc;
namespace DevExtremeSample.Web.Components.jQuery
{
public class JqueryHeadViewComponent : AbpViewComponent
{
public IViewComponentResult Invoke()
{
return View("/Components/jQuery/Default.cshtml");
}
}
}
```
After that, your `*.Web` project should be like as following.
![jquery-head](jquery-head.png)
Then replace your `AbpLayoutHookOptions` with following code block to add `JqueryHeadViewComponent` to `<head>` section.
```csharp
Configure<AbpLayoutHookOptions>(options =>
{
options.Add(
LayoutHooks.Head.Last, //The hook name
typeof(JqueryHeadViewComponent) //The component to add
).Add(
LayoutHooks.Head.Last, //The hook name
typeof(DevExtremeJsViewComponent) //The component to add
);
});
```
Now create `MyScriptContributor.cs` file at your `*.Web` project and paste following codes to your file.
```csharp
using System.Collections.Generic;
using Volo.Abp.AspNetCore.Mvc.UI.Bundling;
using Volo.Abp.AspNetCore.Mvc.UI.Packages.Core;
using Volo.Abp.Modularity;
namespace DevExtremeSample.Web
{
[DependsOn(typeof(CoreScriptContributor))]
public class MyScriptContributor : BundleContributor
{
public override void ConfigureBundle(BundleConfigurationContext context)
{
context.Files.AddIfNotContains("/libs/abp/jquery/abp.jquery.js");
}
}
}
```
Finally, we replace the `JQueryScriptContributor` with `MyScriptContributor`.
Replace the `AbpBundlingOptions` at the `DevExtremeSampleWebModule.cs` file with the following code block.
```csharp
Configure<AbpBundlingOptions>(options =>
{
options
.StyleBundles
.Get(StandardBundles.Styles.Global)
.AddFiles("/libs/devextreme/css/dx.common.css")
.AddFiles("/libs/devextreme/css/dx.light.css");
options.ScriptBundles
.Get(StandardBundles.Scripts.Global)
.Contributors
.Replace<JQueryScriptContributor, MyScriptContributor>();
});
```
### Result
After following this step-by-step article you can use all DevExtreme features in your project.

## Using DevExtreme in ABP Based Application
Hi, in this article, I will explain some cases of DevExtreme usages in ABP based application.
This article will reference [this](https://github.com/abpframework/abp-samples/tree/master/DevExtreme-Mvc) sample.
## Integrate DevExtreme Packages to ABP Framework Based Applications
Please follow [Intergrate DevExtreme documentation](Intergrate-DevExtreme-To-ABP-Based-Application.md) to see each step. This article will not include setup informations.
## Data Storage
We will use an in-memory list for using data storage for this sample.
There is a `SampleDataService.cs` file in `Data` folder at `*.Application.Contracts` project. We store all sample data here.
We did not create `Entities` etc. Because we want to show "How to use DevExtreme?", because of that, in this sample we focused to application and UI layer.
## JSON Serialization
You can see some `[JsonProperty(Name = "OrderId")]` attributes at DTO's. In this sample, we use that attribute on DTO's properties because DevExtreme official resource is suggesting to _disable the conversion in the JSON serializer_ [(ref)](https://js.devexpress.com/Documentation/19_1/Guide/Angular_Components/Visual_Studio_Integration/Add_DevExtreme_to_an_ASP.NET_Core_Angular_Application/#Troubleshooting). **DO NOT DO THAT!**
If you change **the conversion in the JSON serializer**, some pre-build abp modules may occur a problem.
## MVC
You can use some DevExtreme functions to create UI. The following code blocks show you how you can use it with ABP Applicaion Services.
```csharp
Html.DevExtreme().DataGrid<Order>()
.DataSource(d => d.Mvc()
.Controller("Order") // Application Service Name 'without **AppService**'
.LoadAction("GetOrders") // Method Name 'without **Async**'
.InsertAction("InsertOrder")
.UpdateAction("UpdateOrder")
.DeleteAction("DeleteOrder")
.Key("OrderID")
)
```
```csharp
public class OrderAppService : DevExtremeSampleAppService, IOrderAppService
{
public async Task<LoadResult> GetOrdersAsync(DataSourceLoadOptions loadOptions)
{
...
}
public async Task<Order> InsertOrder(string values)
{
...
}
...
}
```
