Visual Studio Code Format Json
Niki Wienberg
Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.
To ensure that this extension is used over other extensions you may have installed, be sure to set it as the default formatter in your VS Code settings. This setting can be set for all languages or by a specific language.
This extension will use prettier from your project's local dependencies (recommended). When the prettier.resolveGlobalModules is set to true the extension can also attempt to resolve global modules. Should prettier not be installed locally with your project's dependencies or globally on the machine, the version of prettier that is bundled with the extension will be used.
Prettier's preview version 3 is supported as of version 9.12.0. It is not included in the extension by default, but can be used by installing locally in your project. Version 10.0.0 of this extension will include prettier 3.0.0 after it is out of preview. To try version 3 now run the following in your project:
This extension supports Prettier plugins when you are using a locally or globally resolved version of prettier. If you have Prettier and a plugin registered in your package.json, this extension will attempt to register the language and provide automatic code formatting for the built-in and plugin languages.
There are multiple options for configuring Prettier with this extension. You can use VS Code settings, prettier configuration files, or an .editorconfig file. The VS Code settings are meant to be used as a fallback and are generally intended only for use on non-project files. It is recommended that you always include a prettier configuration file in your project specifying all settings for your project. This will ensure that no matter how you run prettier - from this extension, from the CLI, or from another IDE with Prettier, the same settings will get applied.
Using Prettier Configuration files to set formatting options is the recommended approach. Options are searched recursively down from the file being formatted so if you want to apply prettier settings to your entire project simply set a configuration in the root. Settings can also be configured through VS Code - however, these settings will only apply while running the extension, not when running prettier through the command line.
Some users may not wish to create a new Prettier config for every project or use the VS Code settings. In order to set a default configuration, set prettier.configPath. However, be careful, if this is set this value will always be used and local configuration files will be ignored.
If you would like to format a document that is configured to be ignored by Prettier either because it is in a .prettierignore file or part of a normally excluded location like node_modules, you can run the command Format Document (Forced) to force the document to be formatted. Forced mode will also ignore any config for requirePragma allowing you to format files without the pragma comment present.
The recommended way of integrating with linters is to let Prettier do the formatting and configure the linter to not deal with formatting rules. You can find instructions on how to configure each linter on the Prettier docs site. You can then use each of the linting extensions as you normally would. For details refer to the Prettier documentation.
This extension utilizes VS Code Workspace Trust features. When this extension is run on an untrusted workspace, it will only use the built in version of prettier. No plugins, local, or global modules will be supported. Additionally, certain settings are also restricted - see each setting for details.
All prettier options can be configured directly in this extension. These settings are used as a fallback when no configuration file is present in your project, see the configuration section of this document for more details. For reference on the options see the prettier documentation.
The default values of these configurations are always to their Prettier 2.0 defaults. In order to use defaults from earlier versions of prettier you must set them manually using your VS Code settings or local project configurations.
NOTE: This setting can have a negative performance impact, particularly on Windows when you have attached network drives. Only enable this if you must use global modules. It is recommended that you always use local modules when possible.
A list of glob patterns to register Prettier formatter. Typically these will be in the format of **/*.abc to tell this extension to register itself as the formatter for all files with the abc extension. This feature can be useful when you have overrides set in your config file to map custom extensions to a parser.
It is likely you will need to also update your prettier config. For example, if I register the following document selector by itself, Prettier still won't know what to do with that file. I either need a Prettier extension that formats .abc file format or I need to configure Prettier.
When a package.json is present in your project and it contains prettier, plugins, or linter libraries this extension will attempt to load these modules from your node_module folder. If you see this error, it most likely means you need to run npm install or yarn install to install the packages in your package.json.
I was longing for a Go-like approach. When working in Go the common approach is to have your editor run go fmt on save, which brings code formatting in line with the Go standard (with hard tabs for indent, by the way!). So whatever mess you make in your editor gets fixed as soon as you save.
Luckily, Omnisharp provides just this. Omnisharp is the language server that provides IDE-like features to editors, like IntelliSense, semantic syntax highlighting, and formatting! I assume you, like 9 million developers before you, are already using Omnisharp through the official C# extension for Visual Studio Code. If not, install that first:
For a full list of available options, check out the Omnisharp wiki on Github. Including the omnisharp.json file in your project seems like a good idea to me, since it unifies formatting options for all developers on a team, regardless of editor and editor configuration.
The devcontainer.json file contains any needed metadata and settings required to configurate a development container for a given well-defined tool and runtime stack. It can be used by tools and services that support the dev container spec to create a development environment that contains one or more development containers.
Metadata properties marked with a ?️️ can be stored in the devcontainer.metadata container image label in addition to devcontainer.json. This label can contain an array of json snippets that will be automatically merged with devcontainer.json contents (if any) when a container is created.
The focus of devcontainer.json is to describe how to enrich a container for the purposes of development rather than acting as a multi-container orchestrator format. Instead, container orchestrator formats can be referenced when needed to manage multiple containers and their lifecycles. Today, devcontainer.json includes scenario specific properties for working without a container orchestrator (by directly referencing an image or Dockerfile) and for using Docker Compose as a simple multi-container orchestrator.
For each command property, if the value is a single string, it will be run in /bin/sh. Use && in a string to execute multiple commands. For example, "yarn install" or "apt-get update && apt-get install -y curl". The array syntax ["yarn", "install"] will invoke the command (in this case yarn) directly without using a shell. Each fires after your source code has been mounted, so you can also run shell scripts from your source tree. For example: bash scripts/install-dev-tools.sh.
The portsAttributes and otherPortsAttributes properties allow you to map default port options for one or more manually or automatically forwarded ports. The following is a list of options that can be set in the configuration object assigned to the property.
The .http file format and editor was inspired by the Visual Studio Code REST Client extension. The Visual Studio 2022 .http editor recognizes .rest as an alternative file extension for the same file format.
To add one or more headers, add each header on its own line immediately after the request line. Don't include any blank lines between the request line and the first header or between subsequent header lines. The format is HeaderName: Value, as shown in the following examples:
When calling an API that authenticates with headers, do not commit any secrets to a source code repository. See the supported methods for storing secrets later in this article, such as ASP.NET Core user secrets, Azure Key Vault and DPAPI encryption.
Variables can be referenced in requests that are defined later in the file. They're referenced by wrapping their names in double curly braces, and . The following example shows two variables defined and used in a request:
Variables can be defined using values of other variables that were defined earlier in the file. The following example uses one variable in the request instead of the two shown in the preceding example:
To give variables different values in different environments, create a file named http-client.env.json. Locate the file in the same directory as the .http file or in one of its parent directories. Here's an example of an environment file:
The environment file is a JSON file that contains one or more named environments, such as "dev" and "remote" in the preceding example. Each named environment contains one or more variables, such as HostAddress in the preceding example. Variables from an environment file are referenced the same way as other variables, as shown in the following example:
