This article is for Chrome Enterprise administrators and developers with experience packaging and publishing Chrome apps and extensions for users.Sometimes, you might not be able to find an app or extension in the Chrome Web Store that meets your users’ needs. If that happens, you can create your own custom app or extension that users can add to their ChromeOS device or Chrome browser. For example, as an administrator, you can automatically install a custom bookmark app that links to your HR system on users’ Chrome devices.Before you begin If your app or extension links to a website as a target in the manifest, use Google Search Console to verify that your organization owns the website. For privately hosted apps and extensions, control which users can publish them to the Chrome Web Store. You can also skip verification for websites that your organization doesn’t own. For details, read Chrome Web Store Permissions.Step 1: Build the app or extensionAs a developer, you can build an app or extension, such as the example bookmark app provided in the steps below. For instructions on building more advanced Chrome apps and extensions, see the Getting Started Tutorial. On a computer, create a folder for the app or extension files, naming it the same as the app or extension name. Create the manifest. Using a text editor, create a JavaScript Object Notation (JSON) file. Here is an example JSON file for a bookmark app. Make sure the JSON code is formatted correctly with the third-party JSON validation tool of your choice. In the app or extension folder, save the file as manifest.json. Create the logo. Create a 128p by 128p logo for your app. In the app folder, save the file as 128.png. Step 2: Test the app or extensionAs a developer, you can test your app or extension to make sure it works in Chrome browser or on a ChromeOS device. Choose the type of test device you need: Apps—Sign in to your Google Account on a Chrome device. Extensions—Sign in to your Google Account on a Chrome device or Chrome browser on a Windows, Mac, or Linux computer. Save the app or extension folder on your test device. Go to chrome://extensions/. At the top right, turn on Developer mode. Click Load unpacked. Find and select the app or extension folder. Open a new tab in Chromeclick Appsclick the app or extension. Make sure

User interface for the extension, so if a user clicks the extension icon from the top bar of chrome, something will pop up. This can be achieved by using the action parameter of the manifest file. See the below sample manifest file.{ "name": "The Name of the extension", "version": "1.0", "description": "The description of the extension", "manifest_version": 3, "background": { "service_worker": "background.js" }, "action": { "default_popup": "popup.html" }}In the above JSON file, we use the default_popup option of the action parameter and give it a file “popup.html.” If someone clicks on the extension icon(present on the top of chrome on the right side of the search bar), then the content inside the popup.html will be executed. This file is beneficial while building extensions. For example, we can build a calculator using the popup.html by adding some javascript which lets us easily access and use the calculator in chrome by just clicking the extension icon. PermissionsMany chrome API functions were restricted to be used in the chrome extension and required special permissions. While building an extension for google chrome, we need to ask for permissions by listing all the permission we required in the manifest file. There are many permissions that we may want to use for our app like,Storage: This permission will let the chrome extension store data by using the storage API of chrome.Bookmarks: Using this permission, our app can create and edit bookmarks.To see the full list of permission, visit the official docs of google chrome extensions. To use any of the restricted functionality in our chrome extension, we need to request permission by adding it to the manifest file. For example, see the below sample manifest file.{ "name": "The Name of the extension", "version": "1.0", "description": "The description of the extension", "manifest_version": 3, "background": { "service_worker": "background.js" }, "action": { "default_popup": "popup.html" }, "permissions": [ "storage", "bookmarks", "history" ]}In the above sample manifest, we have asked for three permissions viz. storage, bookmarks, history. Now we can use these functionalities in our extension.ConclusionIn this tutorial, we have learned how to build chrome extensions.

Google Chrome extensions are small apps created using HTML, CSS, and javascript to add some special functionality to chrome. Many popular Chrome extensions serve users with a variety of options and functionality. Some of the popular chrome extensions are Grammarly, wappalyzer, etc. These extensions are developed for a single purpose like the Grammarly extension is for writers to check grammar. The wappalyzer extension is used to know the technologies from which a website is built. There are many extensions like this. You can search them and install them by visiting the chrome web store.Creating a Chrome extensionThough there are many extensions available in the chrome web store, sometimes we require a custom chrome extension. Due to this, we need to learn how to make a chrome extension to develop it as per our requirements. To create an extension, we need to create a folder for the chrome extension and add the required files there. Creating the manifest fileWhile creating a chrome extension, the first step is to create the project folder. Then in the folder, we need to create a file with the name manifest.json. The manifest.json file is a JSON(Javascript Object Notation) file. This file provides important information about the extension. This information includes the extension name, description, icons path, required permissions, background scripts, etc. A simple manifest file is shown below.{ "name": "The Name of the extension", "version": "1.0", "description": "The description of the extension", "manifest_version": 3}In the above manifest file, we have provided the name, description, version of the chrome extension, and the version of the manifest file. By creating a manifest file, we have created a simple chrome extension. Now let us see how we can load this extension in Google chrome.Loading the extension in ChromeTo load a chrome extension manually in chrome, we need to follow the steps mentioned below.Step 1: First of all, we need to go to the extension page of google chrome by typing chrome://extensions/ in the URL bar.Step 2: After going to the extension page, we need to turn on the developer mode present in the top right corner of theCreating a Chrome Extension: Mastering Manifest JSON and

Article03/29/2024 In this article -->In this article, you learn about the .NET Aspire manifest format. This article serves as a reference guide for deployment tool builders, aiding in the creation of tooling to deploy .NET Aspire projects on specific hosting platforms, whether on-premises or in the cloud..NET Aspire simplifies the local development experience by helping to manage interdependencies between application integrations. To help simplify the deployment of applications, .NET Aspire projects can generate a manifest of all the resources defined as a JSON formatted file.Generate a manifestA valid .NET Aspire project is required to generate a manifest. To get started, createa .NET Aspire project using the aspire-starter .NET template:dotnet new aspire-starter --use-redis-cache ` -o AspireApp && ` cd AspireAppManifest generation is achieved by running dotnet build with a special target:dotnet run --project AspireApp.AppHost\AspireApp.AppHost.csproj ` --publisher manifest ` --output-path ../aspire-manifest.jsonTipThe --output-path supports relative paths. The previous command uses ../aspire-manifest.json to place the manifest file in the root of the project directory.For more information, see dotnet run. The previous command produces the following output:Building...info: Aspire.Hosting.Publishing.ManifestPublisher[0] Published manifest to: .\AspireApp.AppHost\aspire-manifest.jsonThe file generated is the .NET Aspire manifest and is used by tools to support deploying into target cloud environments.NoteYou can also generate a manifest as part of the launch profile. Consider the following launchSettings.json:{ "$schema": " "profiles": { "generate-manifest": { "commandName": "Project", "launchBrowser": false, "dotnetRunMessages": true, "commandLineArgs": "--publisher manifest --output-path aspire-manifest.json" } }}Basic manifest formatPublishing the manifest from the default starter template for .NET Aspire produces the following JSON output:{ "resources": { "cache": { "type": "container.v0", "connectionString": "{cache.bindings.tcp.host}:{cache.bindings.tcp.port}", "image": "redis:7.2.4", "bindings": { "tcp": { "scheme": "tcp", "protocol": "tcp", "transport": "tcp", "containerPort": 6379 } } }, "apiservice": { "type": "project.v0", "path": "../AspireApp.ApiService/AspireApp.ApiService.csproj", "env": { "OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EXCEPTION_LOG_ATTRIBUTES": "true", "OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EVENT_LOG_ATTRIBUTES": "true" }, "bindings": { "http": { "scheme": "http", "protocol": "tcp", "transport": "http" }, "https": { "scheme": "https", "protocol": "tcp", "transport": "http" } } }, "webfrontend": { "type": "project.v0", "path": "../AspireApp.Web/AspireApp.Web.csproj", "env": { "OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EXCEPTION_LOG_ATTRIBUTES": "true", "OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EVENT_LOG_ATTRIBUTES": "true", "ConnectionStrings__cache": "{cache.connectionString}", "services__apiservice__0": "{apiservice.bindings.http.url}", "services__apiservice__1": "{apiservice.bindings.https.url}" }, "bindings": { "http": { "scheme": "http", "protocol": "tcp", "transport": "http" }, "https": { "scheme": "https", "protocol": "tcp", "transport": "http" } } } }}The manifest format JSON consists of a single object called resources, which contains a property for each resource specified in Program.cs (the name argument for each name is used as the property for each of the child resource objects in JSON).Connection string and binding referencesIn the previous example, there are two project resources and one Redis cache resource.

Content ExtractorThis repository contains a collection of tools for extracting and managing text and images from Microsoft PowerPoint slide decks and Word documents.These tools were written to automate the process of tracking assets used across multiple slide decks.The user simply needs to provide a path to a directory where one or more .pptx and/or .word documents are located.The extractor tools will cycle over each file in the given directory and extract text and images.For slide decks, text is logged to a json manifest which logs extracted content slide by slide.Extracted text is pre-processed to remove stop words and use lamentations to stem words to their root.The raw text and pre-processed text are both logged to the json manifest where it can be mined later.Images are all given a unique identifier which is tracked in the json manifest.Images are resized to fit within the bounds of a maximum dimension given by the user.This is done to reduce the amount to data storage needed when extracting large amounts of large images.The extracted images are then processed to calculate color moments for indexing and similarity measurements, which are used to cull duplicate images.Culled duplicate images are still tracked in the manifest so even if the image is removed, it can be traced back to the slide where it was extracted.Comments
