Open the file ClientApp/src/setupProxy.js and change the line that sets the target to use the localhost address and port on the container. Check out the Working with containers topic on the Visual Studio Code documentation site to get started. Docker support in Visual Studio There are two levels of Docker support you can add to a project. As a relatively new feature, private fields also haven't been optimized across all runtimes yet. Click to share on Twitter (Opens in new window), Click to share on LinkedIn (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Reddit (Opens in new window), creating and debugging an ASP.NET Core Docker container. Docker Compose lets you define and run multi-container applications with Docker. Check the Environment variables section and add the following environment variables if not already present: Set the URL to https://localhost:{proxy-port} where {proxy-port} is the port from the proxy server (from step 1). See the contribution guidelines for ideas and guidance on how to improve the extension. Be sure to add these lines both in the first section, to add the installation of the Node package manager npm.exe to the base image, as well as in the build section. Looking for an alternative to monday.com? More specifically, if you select Individual Components, you need to ensure that the Container Development Tools component is selected as shown below. Using Jack Wallen is an award-winning writer for TechRepublic, The New Stack, and Linux New Media. First, you'll need to download Docker for Windows. Clearly there was still room for improvement. We then thought about how to make this change as safely as possible. The Docker tools for Visual Studio Code has released version 1.26.0, bringing built-in support for building and debugging container images using the .NET SDK. Get up and running with ChatGPT with this comprehensive cheat sheet. Does your business need a payroll provider that offers international payroll services? By mangling private properties, the size of VS Code's main workbench.js script went from 12.3 MB to 10.6 MB, a close to 14% reduction. Notice the two drops on the right side. Fill in your desired values in the Create new Azure Container Registry screen. To install the extension, open the Extensions view, search for docker to filter results and select Docker extension authored by Microsoft. However esbuild's conservative approach means that it skips mangling many names because it can't be confident that changing them is safe. That calculus changes if we can get nice optimizations like this essentially for free, say by having our build tool do them for us automatically. Serializing objects or parsing JSON to an expected object shape. To create a production image containing all contents, use the Release configuration. You should see something like the following code: Do not set the launch settings option publishAllPorts to true if you are using a proxy. E-mail us. However, this regular expression only matches against the identifier name. The policy is not intended to focus on the specific technical aspects of configuration management products; thats the responsibility of Video surveillance is often a critical security feature for the purpose of monitoring both human and natural events (e.g., wildlife activity, hazardous weather or accidents/disasters). Surely private properties can be safely mangled and code outside of the class would be none the wiser, right? The extension offers custom tasks that help with launching a service under the debugger and with attaching the debugger to a running service instance. Only once we had worked to reduce this risk, create the right safety nets, and make the cost of adopting mangling almost zero, did we finally feel confident enough to enable it in our builds. That will give you a list of drives available from your computer. Check out the Working with containers topic on the Visual Studio Code documentation site to get started. Now we can provide some more specifics for our new application. Get it now. When the window comes up, dock it on the bottom under the editor pane. Moving closer to plain old JavaScript was also appealing. For the purposes of this example we will select the API project template. See Use the Containers window. There are two levels of Docker support you can add to a project, and the supported options vary by the type of project and the version of Visual Studio. Right-click on your project and select Add | Docker Support. Integrate Docker support and Microsoft's Visual Studio Code with this brief tutorial from expert Jack Wallen. In this post, I want to share how we identified this optimization opportunity, explored approaches to the problem, and eventually shipped this 20% size reduction. Our first idea was to try adopting JavaScript's native #private fields everywhere in our codebase. Type Docker in the search bar and wait for the results to populate. During minification, mangling shortens long identifier names, transforming code such as: Since JavaScript is shipped as source text, reducing the length of identifier names actually decreases the program's size. As long as the exports were only used internally, I felt confident we could shorten them without changing the behavior of the code. Without care, renaming can introduce name collisions (thankfully TypeScript reports these as errors). Very dissapointed. Integrate Docker support and Microsoft's Visual Studio Code with this brief tutorial from expert Jack Wallen. Sure that's less than some of the individual gifs from our release notes, but that's still nothing to sniff at! Edit Docker in Visual Studio Code The Docker extension makes it easy to build, manage, and deploy containerized applications in Visual Studio Code. Brag to your friends about how hip and happening you are. Heres how its done. Prerequisites To debug apps in a local Docker container, the following tools must be installed: Visual Studio 2022 with the Web Development workload installed To run Docker containers locally, you must have a local Docker client. In addition, you can use the Problems panel (Ctrl+Shift+M on Windows/Linux, Shift+Command+M on Mac) to view common errors for Dockerfile and docker-compose.yml files. I know that optimization probably seems more than a little silly if you're coming from a compiled language, but here in the wonderful world of JavaScript we gladly take wins like this wherever we can find them! Questions? Upgraded to the new version of Visual Studio for Mac and the Add Docker Support menu item is missing. You should see the installation steps associated with npm.exe. Refer to Dockerfile reference for an understanding of the commands within it. As explained in this blog post, the new project dialog in Visual Studio has been given an overhaul. When debugging, the JavaScript client runs on the host machine, but the ASP.NET Core server code runs in the container. Next, try hitting a breakpoint in the server-side ASP.NET Core code. Development frameworks, platforms, and tools that do not offer a rich development experience will ultimately lack in adoption. The VS Code codebase does not follow this naming convention consistently, and there are also a few places where we have public properties that start with _ (typically this is done when a property needs to be accessible externally but shouldn't be treated as API, such as in tests). This issue is read only, because it has been in the Closed - Fixed state for over 90 days. Not bad at all given that, besides a few very minor fixes to unsafe patterns in our sources, these savings were basically free. If the check box isn't checked, a single port (80) is exposed for HTTP traffic. Install Docker on your machine and add it to the system path. Looking through our newly mangled and minified sources, I was crestfallen to see provideWorkspaceTrustExtensionProposals and plenty of other lengthy names. You can rearrange the Docker view panes by dragging them up or down with a mouse and use the context menu to hide or show them. "Imagine this: code explanations, debugging assistance, unit test suggestions, and more right in the IDE.". You can get IntelliSense when editing your Dockerfile and docker-compose.yml files, with completions and syntax help for common commands. The key to our success this time was identifying a case (private properties), where name mangling would likely be safe and where the optimization would still make a significant improvement. All reductions in total, this file is now 20% smaller than it would be without mangling. Not too shabby considering we got this reduction without deleting any code and without any major refactorings in our codebase. To start again using the Publish dialog, delete the publish profile by using the Delete link on this page, and then choose Publish again. We couldn't be 100% sure we were only mangling private properties without touching other code. The download includes a PDF and Word document. This makes sense because while our container is started, nothing is actually deployed to it yet. For more information on available commands, see Get started with Azure CLI. Change the configuration drop-down to Release and build the app. Docker for Visual Studio Code The Docker extension makes it easy to build, manage, and deploy containerized applications from Visual Studio Code. After Docker for Windows is installed, you'll find the Docker icon sitting in the Notifications popup on your taskbar. Ideally, some day much of this work won't be necessary at all. Similar to when working with Visual Studio 2017, a Dockerfile is generated with four named build stages (base, build, publish, and final). The project uses the SPA Proxy during debugging. I'm really proud of the end result and just as proud of how we went about achieving it. The complete Dockerfile should now look something like this: Update the .dockerignore file by removing the **/bin. I have become quite accustomed to the previous version however, I must admit the improvements are very intuitive. Click on the Files tab, and expand the app folder to see your published application files. 2023 TechnologyAdvice. This all came together so that Joh and I could work in our spare time to ship a fairly drastic change with almost no impact to the other developers working on VS Code. In a recent TechRepublic video, Jack Wallen showed how to add Docker support to Visual Studio Code. Again this work largely happens because we keep track of our code size and really hate seeing it increase. Create a project and add Docker support Create a new project using the ASP.NET Core with React.js template.
