VisualStudio – JSON Viewer: How this extension can improve your JSON workflow



JSON is a data format that is common in configuration files like package.json or project.json. We also use it extensively in Visual Studio Code for our configuration files. When opening a file that ends with .json, VS Code provides features to make it simpler to write or modify the file's content.




VisualStudio – JSON Viewer, excellent extension to work with JSON contents




In addition to the default JSON mode following the JSON specification, VS Code also has a JSON with Comments (jsonc) mode. This mode is used for the VS Code configuration files such as settings.json, tasks.json, or launch.json. When in the JSON with Comments mode, you can use single line (//) as well as block comments (/* */) as used in JavaScript. The mode also accepts trailing commas, but they are discouraged and the editor will display a warning.


The current editor mode is indicated in the editor's Status Bar. Select the mode indicator to change the mode and to configure how file extensions are associated to modes. You can also directly modify the files.associations setting to associate file names or file name patterns to jsonc.


To map a schema that is located in the workspace, use a relative path. In this example, a file in the workspace root called myschema.json will be used as the schema for all files ending with .foo.json.


The extension lets you mount workspace files into the container from the local file system or copy them into it once the container is running. Extensions are installed and run inside the container to have full access to the tools, platform, and file system. You then work with Visual Studio Code as if everything were running locally on your machine, except now they are separated inside a container.


There are number of extensions in Visual Studio Code (VS Code) to prettify JSON files. But is there an extension or setting, which enables me to view all *.json files pre-formatted / pre prettified? I find it tedious to constantly press shift-alt-F + ctrl-s when viewing ugly one line json-data, especially if the content of the file is being updated regularly back to pre-formatted form.


Visual Studio uses a CMake configuration file to drive CMake generation and build. CMakePresets.json is supported by Visual Studio 2019 version 16.10 or later and is the recommended CMake configuration file. CMakePresets.json is supported directly by CMake and can be used to drive CMake generation and build from Visual Studio, from VS Code, in a Continuous Integration pipeline, and from the command line on Windows, Linux, and Mac. For more information on CMakePresets.json, see Configure and build with CMake Presets. CMakeSettings.json is available for customers using an earlier version of Visual Studio. For more information on CMakeSettings.json, see Customize CMake build settings.


Visual Studio uses a CMake configuration file to drive CMake builds. CMake configuration files encapsulate build options like native build tool switches and environment variables. If CMakePresets.json is your active configuration file, see Configure and build with CMake Presets. If CMakeSettings.json is your active configuration file, see Customize CMake build settings. CMakePresets.json is available in Visual Studio 2019 version 16.10 or later and is the recommended CMake configuration file.


In Visual Studio 2022 version 17.1 and later, CMake functionality won't be enabled automatically if your root folder doesn't contain a CMakeLists.txt file. Instead, a dialog will prompt you on whether you'd like to enable CMake functionality for your project. If you decline, CMake cache generation won't start and CMake configurations (from CMakeSettings.json or CMakePresets.json) won't appear in the configuration dropdown. If you accept, you'll be taken to a workspace-level configuration file, CMakeWorkspaceSettings.json (stored in the .vs directory), to specify the folders you'd like to enable CMake for. (These folders contain your root CMakeLists.txt files).


If CMakePresets.json is your active configuration file, you'll need to set the path to vcpkg.cmake in CMakePresets.json. We recommend using the VCPKG_ROOT environment variable instead of an absolute path to keep the file shareable. For more information, see Enable vcpkg integration with CMake Presets. CMakePresets.json is available in Visual Studio 2019 version 16.10 or later and is the recommended CMake configuration file.


When you import an existing CMakeCache.txt file, Visual Studio automatically extracts customized variables and creates a pre-populated CMakeSettings.json file based on them. The original cache isn't modified in any way. It can still be used from the command line, or with whatever tool or IDE used to generate it. The new CMakeSettings.json file is placed alongside the project's root CMakeLists.txt. Visual Studio generates a new cache based the settings file. You can override automatic cache generation in the Tools > Options > CMake > General dialog.


You can customize build configurations, environment variables, command-line arguments, and other settings in the CMakeSettings.json file. It lets you make changes without modifying the CMakeLists.txt file. For more information, see Customize CMake settings.


When significant changes are made to the CMakeSettings.json or to CMakeLists.txt files, Visual Studio automatically reruns the CMake configure step. If the configure step finishes without errors, the information that's collected is available in C++ IntelliSense and language services. It's also used in build and debug operations.


You can limit builds and debug sessions to a subset of the projects in the workspace. Create a new configuration with a unique name in the CMakeSettings.json file. Then, apply the configuration to those projects only. When that configuration is selected, IntelliSense and the build and debug commands only apply to those specified projects.


This article shows how to use the mssql extension for Visual Studio Code (Visual Studio Code) to work with databases in SQL Server on Windows, macOS, and Linux, as well as Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. The mssql extension for Visual Studio Code lets you connect to a SQL Server, query with Transact-SQL (T-SQL), and view the results.


The mssql extension for VS Code v1.17.0 and later includes an important change to the Encrypt property, which is now enabled (set to True) by default for MSSQL provider connections, and SQL Server must be configured with TLS certificates signed by a trusted root certificate authority. In addition, if an initial connection attempt fails with encryption enabled (default), the mssql extension will provide a notification prompt with an option to attempt the connection with Trust Server Certificate enabled. Both the Encrypt and Trust server certificate properties are also available for manual editing in the user settings file (settings.json). The best practice is to support a trusted encrypted connection to the server.


Decent plugin. It does basic json formatting and syntax highlighting, however it has one "feature" which renders it un-usable. It will randomly, seemingly without a pattern highlight entire blocks of json. So if you're typing this means that the entire block is replaced. Not an acceptable thing for a code editor to do!


This plugin is so good, thank you very much for your excellent work!But I have a little problem, when the size of JSON file getting bigger, it is so difficult to type contents to the file, it will be stuck for validation work, is it possible to add an optional validation feature? or a switch to turn off the validation. Thank you.


I am using Ubuntu 13.04 (Kernel 3.5.44) Unfortunately, this plug in starts acting up and does not allow the json file to be saved with a NullPointerException (no further info provided by Eclipse). It hampered my delivery efforts.


In the previous article, Getting started with Visual Studio Code (VS Code), we took a detailed overview of the popular code editor. It supports various programming languages t-SQL, Python, PHP, AWS CLI, PowerShell, etc. We need to use extensions in the VS code to work with these languages. For example, if we open the T-SQL script, it recommends you for the below extension.


We can work on SQL scripts without extension as well, but it does not give added functionality to work on T-SQL. In the below image, we see that you do not get different color codes for the database object. It treats the whole script as a regular file.


Unlike formatting, linting is specific to the Python extension. To enable linting, choose a linter by running Python: Select Linter on the Command Palette. You can also enable one or more linters in your settings. For example, to enable the Bandit and Pylint linters, edit your settings.json:


There's two important things to notice here. First, Code is smart enough to associate certain file types with available Extensions. Extensions are plugins that add extra features to the editor. Secondly, notice that the file is treated as "Plain Text". This is the default behavior when Code doesn't know how to work with a file type. So while Code recognizes there's extensions out there that will help, for now it's going to treat it as just a text file.


Once you've done that, Code will forever associate any file with the .geojson extension as JSON, giving you nice color coding and syntax checking. Now to be clear, that's JSON checking, not GeoJSON checking. So for example, this is invalid JSON that Code would immediately flag:


As you can see, for users of Visual Studio Code you've got a lot of options for working with geojson files. Of course, other editors will have some of the same features, like JSON Schema validation, and you should check your relevant documentation.


As is, ESLint produces a highlighted message for all console.log() statements in app.js. In some cases, removing console.log statements may not be a priority. You can customize the ESLint configuration to allow console.log statements without producing an error message. ESLint configuration rules can be modified in the .eslintrc.json file. 2ff7e9595c
