 # Umbraco CMS Build
 
-This guide will explain how you can build the Umbraco CMS from the source code. You will most likely want to do this if your are setting up a local development environment for contributing code updates to the project. You will need this in order to develop and test your fix or feature.

-### Familiarizing yourself with the code
+To build the front end you'll need to open the command pallet (<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>P</kbd>) and run `>Tasks: Run Task` followed by `Client Watch` and then run the `Client Build` task in the same way.
 
-Umbraco is a .NET application using C#. The solution is broken down into multiple projects.  There are several class libraries. The `Umbraco.Web.UI` project is the main project that hosts the back office and login screen. This is the project you will want to run to see your changes.
-
-There are two web projects in the solution with client-side assets based on TypeScript, `Umbraco.Web.UI.Client` and `Umbraco.Web.UI.Login`.
-
-There are a few different ways to work locally when implementing features or fixing issues with the Umbraco CMS. Depending on whether you are working solely on the front-end, solely on the back-end, or somewhere in between, you may find different workflows work best for you.
-
-Here are some suggestions based on how we work on developing Umbraco at HQ.
-
-### First checkout
-
-When you first clone the source code, build the whole solution via your IDE. You can then start the `Umbraco.Web.UI` project via the IDE or the command line and should find everything across front and back-end is built and running.
+You can also run the tasks manually on the command line:
 
 ```
-cd <solution root>\src\Umbraco.Web.UI
-dotnet run --no-build
+cd src\Umbraco.Web.UI.Client
+npm i
+npm run dev
 ```
 
-When the page loads in your web browser, you can follow the installer to set up a database for debugging. When complete, you will have an empty Umbraco installation to begin working with. You may also wish to install a [starter kit][https://marketplace.umbraco.com/category/themes-&-starter-kits] to ease your debugging.
+If you just want to build the UI Client to `Umbraco.Web.UI` then instead of running `dev`, you can do: `npm run build`.
 
-### Back-end only changes
-
-If you are working on back-end only features, when switching branches or pulling down the latest from GitHub, you will find the front-end getting rebuilt periodically when you look to build the back-end changes. This can take a while and slow you down. So if for a period of time you don't care about changes in the front-end, you can disable this build step.
-
-Go to `Umbraco.Cms.StaticAssets.csproj` and comment out the following lines of MsBuild by adding a REM statement in front:
+The login screen is a different frontend build, for that one you can run it as follows:
 
 ```
-REM npm ci --no-fund --no-audit --prefer-offline
-REM npm run build:for:cms
+cd src\Umbraco.Web.UI.Login
+npm i
+npm run dev
 ```
 
-Just be careful not to include this change in your PR.
+If you just want to build the Login screen to `Umbraco.Web.UI` then instead of running `dev`, you can do: `npm run build`.
 
-### Front-end only changes
+**The initial Gulp build might take a long time - don't worry, this will be faster on subsequent runs.**
 
-Conversely, if you are working on front-end only, you want to build the back-end once and then run it. Before you do so, update the configuration in `appSettings.json` to add the following under `Umbraco:Cms:Security`:
+You might run into [Gulp quirks](#gulp-quirks).
+
+The caching for the back office has been described as 'aggressive' so we often find it's best when making back office changes to [disable caching in the browser (check "Disable cache" on the "Network" tab of developer tools)][disable browser caching] to help you to see the changes you're making.
+
+To run the C# portion of the project, either hit <kbd>F5</kbd> to begin debugging, or manually using the command line:
 
 ```
-"BackOfficeHost": "http://localhost:5173",
-"AuthorizeCallbackPathName": "/oauth_complete",
-"AuthorizeCallbackLogoutPathName": "/logout",
-"AuthorizeCallbackErrorPathName": "/error"
+dotnet watch --project .\src\Umbraco.Web.UI\Umbraco.Web.UI.csproj
 ```
 
-Then run Umbraco from the command line.
+**The initial C# build might take a _really_ long time (seriously, go and make a cup of coffee!) - but don't worry, this will be faster on subsequent runs.**
 
-```
-cd <solution root>\src\Umbraco.Web.UI
-dotnet run --no-build
-```
+When the page eventually loads in your web browser, you can follow the installer to set up a database for debugging. You may also wish to install a [starter kit][starter kits] to ease your debugging.
 
-In another terminal window, run the following to watch the front-end changes and launch Umbraco using the URL indicated from this task.
+#### Debugging with Visual Studio
 
-```
-cd <solution root>\src\Umbraco.Web.UI.Client
-npm run dev:server
-```
+In order to build the Umbraco source code locally with Visual Studio, first make sure you have the following installed.
 
-You'll find as you make changes to the front-end files, the updates will be picked up and your browser refreshed automatically.
+  * [Visual Studio 2022 v17+ with .NET 7+](https://visualstudio.microsoft.com/vs/) ([the community edition is free](https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=Community&rel=15) for you to use to contribute to Open Source projects)
+  * [Node.js v14+](https://nodejs.org/en/download/)
+  * npm v7+ (installed with Node.js)
+  * [Git command line](https://git-scm.com/download/)
 
-> [!NOTE]
-> The caching for the back office has been described as 'aggressive' so we often find it's best when making back office changes to [disable caching in the browser (check "Disable cache" on the "Network" tab of developer tools)][disable browser caching] to help you to see the changes you're making.
+The easiest way to get started is to open `umbraco.sln` in Visual Studio.
 
-Whilst most of the backoffice code lives in `Umbraco.Web.UI.Client`, the login screen is in a separate project. If you do any work with that you can build with:
+To build the front end, you'll first need to run `cd src\Umbraco.Web.UI.Client && npm install`  in the command line (or `cd src\Umbraco.Web.UI.Client; npm install` in PowerShell). Then find the Task Runner Explorer (View → Other Windows → Task Runner Explorer) and run the `build` task under `Gulpfile.js`. You may need to refresh the Task Runner Explorer before the tasks load.
 
-```
-cd <solution root>\src\Umbraco.Web.UI.Login
-npm run build
-```
+If you're working on the backoffice, you may wish to run the `dev` command instead while you're working with it, so changes are copied over to the appropriate directories and you can refresh your browser to view the results of your changes.
 
-In both front-end projects, if you've refreshed your branch from the latest on GitHub you may need to update front-end dependencies.
+**The initial Gulp build might take a long time - don't worry, this will be faster on subsequent runs.**
 
-To do that, run:
+You might run into [Gulp quirks](#gulp-quirks).
 
-```
-npm ci --no-fund --no-audit --prefer-offline

-### Full-stack changes
+"The rest" is a C# based codebase, which is mostly ASP.NET Core MVC based. You can make changes, build them in Visual Studio, and hit <kbd>F5</kbd> to see the result.
 
-If working across both front and back-end, follow both methods and use `dotnet watch`, or re-run `dotnet run` (or `dotnet build` followed by `dotnet run --no-build`) whenever you need to update the back-end code.
+**The initial C# build might take a _really_ long time (seriously, go and make a cup of coffee!) - but don't worry, this will be faster on subsequent runs.**
 
-Request and response models used by the management APIs are made available client-side as generated code. If you make changes to the management API, you can re-generate the typed client code with:
-
-```
-cd <solution root>\src\Umbraco.Web.UI.Client
-npm run generate:server-api-dev
-```
-
-Please also update the `OpenApi.json` file held in the solution by copying and pasting the output from `/umbraco/swagger/management/swagger.json`.

-# Contribution Guidelines
-
-## Thoughts, links, and questions
-
-In the high probability that you are porting something from angular JS then here are a few helpful tips for using Lit:
-
-Here is the LIT documentation and playground: [https://lit.dev](https://lit.dev)
-
-### What is the process of contribution?
-
--   Read the [README](README.md) to learn how to get the project up and running
--   Find an issue marked as [community/up-for-grabs](https://github.com/umbraco/Umbraco.CMS.Backoffice/issues?q=is%3Aissue+is%3Aopen+label%3Acommunity%2Fup-for-grabs) - note that some are also marked [good first issue](https://github.com/umbraco/Umbraco.CMS.Backoffice/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) which indicates they are simple to get started on
--   Umbraco HQ owns the Management API on the backend, so features can be worked on in the frontend only when there is an API, or otherwise if no API is required
--   A contribution should be made in a fork of the repository
--   Once a contribution is ready, a pull request should be made to this repository and HQ will assign a reviewer
--   A pull request should always indicate what part of a feature it tries to solve, i.e. does it close the targeted issue (if any) or does the developer expect Umbraco HQ to take over
-
-## Contributing in general terms
-
-A lot of the UI has already been migrated to the new backoffice. Generally speaking, one would find a feature on the projects board, locate the UI in the old backoffice (v11 is fine), convert it to Lit components using the UI library, put the business logic into a store/service, write tests, and make a pull request.
-
-We are also very keen to receive contributions towards **documentation, unit testing, package development, accessibility, and just general testing of the UI.**
-
-## The Management API
-
-The management API is the colloquial term used to describe the new backoffice API. It is built as a .NET Web API, has a Swagger endpoint (/umbraco/swagger), and outputs an OpenAPI v3 schema, that the frontend consumes.
-
-The frontend has an API formatter that takes the OpenAPI schema file and converts it into a set of TypeScript classes and interfaces.
-
-**Current schema for API:**
-
-[https://raw.githubusercontent.com/umbraco/Umbraco-CMS/v13/dev/src/Umbraco.Cms.Api.Management/OpenApi.json](https://raw.githubusercontent.com/umbraco/Umbraco-CMS/v15/dev/src/Umbraco.Cms.Api.Management/OpenApi.json)
-
-**How to convert it:**
-
--   Run `npm run generate:server-api`
-
-## A contribution example
-
-### Example: Published Cache Status Dashboard

-
-### Functionality
-
-**HTML**
-
-The simplest approach is to copy over the HTML from the old backoffice into a new Lit element (check existing elements in the repository, e.g. if you are working with a dashboard, then check other dashboards, etc.). Once the HTML is inside the `render` method, it is often enough to simply replace `<umb-***>` elements with `<uui-***>` and replace a few of the attributes. In general, we try to build as much UI with Umbraco UI Library as possible.
-
-**Controller**
-
-The old AngularJS controllers will have to be converted into modern TypeScript and will have to use our new services and stores. We try to abstract as much away as possible, and mostly you will have to make API calls and let the rest of the system handle things like error handling and so on. In the case of this dashboard, we only have a few GET and POST requests. Looking at the new Management API, we find the PublishedCacheService, which is the new API controller to serve data to the dashboard.
-
-To make the first button work, which simply just requests a new status from the server, we must make a call to `PublishedCacheService.getPublishedCacheStatus()`. An additional thing here is to wrap that in a friendly function called `tryExecuteAndNotify`, which is something we make available to developers to automatically handle the responses coming from the server and additionally use the Notifications to notify of any errors:
-
-```typescript
-import { tryExecuteAndNotify } from '@umbraco-cms/backoffice/resources';
-import { PublishedCacheService } from '@umbraco-cms/backoffice/external/backend-api';
-
-private _getStatus() {
-  const { data: status } = await tryExecuteAndNotify(this, PublishedCacheService.getPublishedCacheStatus());
-
-  if (status) {
-    // we now have the status
-    console.log(status);
-  }
-}
-```
-
-### State (buttons, etc)
-
-It is a good idea to make buttons indicate a loading state when awaiting an API call. All `<uui-button>` support the `.state` property, which you can set around API calls:
-
-```typescript
-@state()
-private _buttonState: UUIButtonState = undefined;
-
-private _getStatus() {
-  this._buttonState = 'waiting';
-
-  [...await...]
-
-  this._buttonState = 'success';
-}
-```
-
-## Making the dashboard visible
-
-### Add to internal manifests
-
-All items are declared in a `manifests.ts` file, which is located in each section directory.
-
-To declare the Published Cache Status Dashboard as a new manifest, we need to add the section as a new json object that would look like this:
-
-```typescript
-{
-	type: 'dashboard',
-	alias: 'Umb.Dashboard.PublishedStatus',
-	name: 'Published Status Dashboard',
-	elementName: 'umb-dashboard-published-status',
-	element: () => import('./published-status/dashboard-published-status.element.js'),
-	weight: 200,
-	meta: {
-		label: 'Published Status',
-		pathname: 'published-status',
-	},
-	conditions: [
-		{
-			alias: 'Umb.Condition.SectionAlias',
-			match: 'Umb.Section.Settings',
-		},
-	],
-},
-```
-
-Let’s go through each of these properties…
-
--   Type: can be one of the following:
-
-    -   section - examples include: `Content`, `Media`
-    -   dashboard - a view within a section. Examples include: the welcome dashboard
-    -   propertyEditorUi
-    -   editorView
-    -   propertyAction
-    -   tree
-    -   editor
-    -   treeItemAction
-
--   Alias: is the unique key used to identify this item.
--   Name: is the human-readable name for this item.
-
--   ElementName: this is the customElementName declared on the element at the top of the file i.e
-
-```typescript
-@customElement('umb-dashboard-published-status')
-```
-
--   Js: references a function call to import the file that the element is declared within
-
--   Weight: allows us to specify the order in which the dashboard will be displayed within the tabs bar
-
--   Meta: allows us to reference additional data - in our case, we can specify the label that is shown in the tabs bar and the pathname that will be displayed in the URL
-
--   Conditions: allows us to specify the conditions that must be met for the dashboard to be displayed. In our case, we are specifying that the dashboard will only be displayed within the Settings section
-
-## API mock handlers
-
-Running the app with `npm run dev`, you will quickly notice the API requests turn into 404 errors. To hit the API, we need to add a mock handler to define the endpoints that our dashboard will call. In the case of the Published Cache Status section, we have several calls to work through. Let’s start by looking at the call to retrieve the current status of the cache:
-
-![Published Status Dashboard](/.github/img/contributing/status-of-cache.png)
-
-From the existing functionality, we can see that this is a string message that is received as part of a `GET` request from the server.
-
-So to define this, we must first add a handler for the Published Status called `published-status.handlers.ts` within the mocks/domains folder. In this file we will have code that looks like the following:
-
-```typescript
-const { rest } = window.MockServiceWorker;
-import { umbracoPath } from "@umbraco-cms/backoffice/utils";
-
-export const handlers = [
-    rest.get(umbracoPath("/published-cache/status"), (_req, res, ctx) => {
-        return res(
-            // Respond with a 200 status code
-            ctx.status(200),
-            ctx.json<string>(
-                "Database cache is ok. ContentStore contains 1 item and has 1 generation and 0 snapshot. MediaStore contains 5 items and has 1 generation and 0 snapshot."
-            )
-        );
-    }),
-];
-```
-
-This is defining the `GET` path that we will call through the resource: `/published-cache/status`
-
-It returns a `200 OK` response and a string value with the current “status” of the published cache for us to use within the element
-
-An example `POST` is similar. Let’s take the “Refresh status” button as an example:
-
-![Published Status Dashboard](/.github/img/contributing/refresh-status.png)
-
-From our existing functionality, we can see that this makes a `POST` call to the server to prompt a reload of the published cache. So we would add a new endpoint to the mock handler that would look like:
-
-```typescript
-rest.post(umbracoPath('/published-cache/reload'), async (_req, res, ctx) => {
- return res(
-    // Simulate a 1 second delay for the benefit of the UI
-    ctx.delay(1000)
-    // Respond with a 201 status code
-    ctx.status(201)
- );
-})
-```
-
-Which is defining a new `POST` endpoint that we can add to the core API fetcher using the path `/published-cache/reload`.
-
-This call returns a simple `OK` status code and no other object.
-
-## Storybook stories
-
-We try to make good Storybook stories for new components, which is a nice way to work with a component in an isolated state. Imagine you are working with a dialog on page 3 and have to navigate back to that every time you make a change - this is now eliminated with Storybook as you can just make a story that displays that step. Storybook can only show one component at a time, so it also helps us to isolate view logic into more and smaller components, which in turn are more testable.
-

-
--   Locally: `npm run storybook`

-
-## Testing
-
-There are two testing tools on the backoffice: unit testing and end-to-end testing.
-
-### Unit testing
-
-We are using a tool called Web Test Runner which spins up a bunch of browsers using Playwright with the well-known jasmine/chai syntax. It is expected that any new component/element has a test file named “&lt;component>.test.ts”. It will automatically be picked up and there are a set of standard tests we apply to all components, which checks that they are registered correctly and they pass accessibility testing through Axe.
-
-Working with playwright: [https://playwright.dev/docs/intro](https://playwright.dev/docs/intro)
-
-## Putting it all together
-
-When we are finished with the dashboard we will hopefully have something akin to this [real-world example of the actual dashboard that was migrated](https://github.com/umbraco/Umbraco.CMS.Backoffice/tree/main/src/backoffice/settings/dashboards/published-status).
