# Welcome to your VS Code Extension
|
|||
|
|
|
|||
|
|
## What's in the folder
|
|||
|
|
|
|||
|
|
* This folder contains all of the files necessary for your extension.
|
|||
|
|
* `package.json` - this is the manifest file in which you declare your extension and command.
|
|||
|
|
* The sample plugin registers a command and defines its title and command name. With this information VS Code can show the command in the command palette. It doesn’t yet need to load the plugin.
|
|||
|
|
* `src/extension.ts` - this is the main file where you will provide the implementation of your command.
|
|||
|
|
* The file exports one function, `activate`, which is called the very first time your extension is activated (in this case by executing the command). Inside the `activate` function we call `registerCommand`.
|
|||
|
|
* We pass the function containing the implementation of the command as the second parameter to `registerCommand`.
|
|||
|
|
|
|||
|
|
## Get up and running straight away
|
|||
|
|
|
|||
|
|
* Press `F5` to open a new window with your extension loaded.
|
|||
|
|
* Run your command from the command palette by pressing (`Ctrl+Shift+P` or `Cmd+Shift+P` on Mac) and typing `Hello World`.
|
|||
|
|
* Set breakpoints in your code inside `src/extension.ts` to debug your extension.
|
|||
|
|
* Find output from your extension in the debug console.
|
|||
|
|
|
|||
|
|
## Make changes
|
|||
|
|
|
|||
|
|
* You can relaunch the extension from the debug toolbar after changing code in `src/extension.ts`.
|
|||
|
|
* You can also reload (`Ctrl+R` or `Cmd+R` on Mac) the VS Code window with your extension to load your changes.
|
|||
|
|
|
|||
|
|
## Explore the API
|
|||
|
|
|
|||
|
|
* You can open the full set of our API when you open the file `node_modules/vscode/vscode.d.ts`.
|
|||
|
|
|
|||
|
|
## Run tests
|
|||
|
|
|
|||
|
|
* Open the debug viewlet (`Ctrl+Shift+D` or `Cmd+Shift+D` on Mac) and from the launch configuration dropdown pick `Extension Tests`.
|
|||
|
|
* Press `F5` to run the tests in a new window with your extension loaded.
|
|||
|
|
* See the output of the test result in the debug console.
|
|||
|
|
* Make changes to `test/extension.test.ts` or create new test files inside the `test` folder.
|
|||
|
|
* By convention, the test runner will only consider files matching the name pattern `**.test.ts`.
|
|||
|
|
* You can create folders inside the `test` folder to structure your tests any way you want.
|
|||
|
|
|

## Go further
|
|||
|
|
|
|||
|
|
* Reduce the extension size and improve the startup time by [bundling your extension](https://code.visualstudio.com/api/working-with-extensions/testing-extension).
|
|||
|
|
* [Publish your extension](https://code.visualstudio.com/api/working-with-extensions/publishing-extension) on the VSCode extension marketplace.
|
