# Welcome to your first 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.
|
|||
|
|
* `extension.js` - 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 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 `extension.js`
|
|||
|
|
* 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 `Launch 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.js` or create new test files inside the `test` folder
|
|||
|
|
* by convention, the test runner will only consider files matching the name pattern `**.test.js`
|
|||
|
|
* you can create folders inside the `test` folder to structure your tests any way you want
