Build responsive, mobile-first projects on the web with the world’s most popular front-end component library. Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Visual studio makes it easy to identify which classes are coming from the Bootstrap. Here is the common steps (not only for Bootstrap) to enable css IntelliSense in VS Code: Step 1: Go to or (Installation steps are already there). Developer community 2.
IntelliSense is a general term for various code editing features including: code completion, parameter info, quick info, and member lists. IntelliSense features are sometimes called by other names such as 'code completion', 'content assist', and 'code hinting.'
IntelliSense for your programming language
Visual Studio Code IntelliSense is provided for JavaScript, TypeScript, JSON, HTML, CSS, SCSS, and Less out of the box. VS Code supports word based completions for any programming language but can also be configured to have richer IntelliSense by installing a language extension.
Below are the most popular language extensions in the Marketplace. Click on an extension tile below to read the description and reviews to decide which extension is best for you.
IntelliSense features
VS Code IntelliSense features are powered by a language service. A language service provides intelligent code completions based on language semantics and an analysis of your source code. If a language service knows possible completions, the IntelliSense suggestions will pop up as you type. If you continue typing characters, the list of members (variables, methods, etc.) is filtered to only include members containing your typed characters. Pressing Tab or Enter will insert the selected member.
You can trigger IntelliSense in any editor window by typing ⌃Space (Windows, Linux Ctrl+Space) or by typing a trigger character (such as the dot character (.) in JavaScript).
Tip: The suggestions widget supports CamelCase filtering, meaning you can type the letters which are upper cased in a method name to limit the suggestions. For example, 'cra' will quickly bring up 'createApplication'.
If you prefer, you can turn off IntelliSense while you type. See Customizing IntelliSense below to learn how to disable or customize VS Code's IntelliSense features.
As provided by the language service, you can see quick info for each method by either pressing ⌃Space (Windows, Linux Ctrl+Space) or clicking the info icon. The accompanying documentation for the method will now expand to the side. The expanded documentation will stay so and will update as you navigate the list. You can close this by pressing ⌃Space (Windows, Linux Ctrl+Space) again or by clicking on the close icon.
After choosing a method you are provided with parameter info.
When applicable, a language service will surface the underlying types in the quick info and method signatures. In the image above, you can see several
any
types. Because JavaScript is dynamic and doesn't need or enforce types, any
suggests that the variable can be of any type.Types of completions
The JavaScript code below illustrates IntelliSense completions. IntelliSense gives both inferred proposals and the global identifiers of the project. The inferred symbols are presented first, followed by the global identifiers (shown by the Word icon).
VS Code IntelliSense offers different types of completions, including language server suggestions, snippets, and simple word based textual completions.
Methods and Functions | method , function , constructor |
Variables | variable |
Fields | field |
Type parameters | typeParameter |
Constants | constant |
Classes | class |
Interfaces | interface |
Structures | struct |
Events | event |
Operators | operator |
Modules | module |
Properties and Attributes | property |
Values and Enumerations | value , enum |
References | reference |
Keywords | keyword |
Files | file |
Folders | folder |
Colors | color |
Unit | unit |
Snippet prefixes | snippet |
Words | text |
Customizing IntelliSense
You can customize your IntelliSense experience in settings and key bindings.
Settings
The settings shown below are the default settings. You can change these settings in your
settings.json
file as described in User and Workspace Settings.Tab Completion
The editor supports 'tab completion' which inserts the best matching completion when pressing Tab. This works regardless of the suggest widget showing or not. Also, pressing Tab after inserting a suggestions will insert the next best suggestion.
By default, tab completion is disabled. Use the
editor.tabCompletion
setting to enable it. These values exist:off
- (default) Tab completion is disabled.on
- Tab completion is enabled for all suggestions and repeated invocations insert the next best suggestion.onlySnippets
- Tab completion only inserts static snippets which prefix match the current line prefix.
Locality Bonus
Sorting of suggestions depends on extension information and on how well they match the current word you are typing. In addition, you can ask the editor to boost suggestions that appear closer to the cursor position, using the
editor.suggest.localityBonus
setting.In above images you can see that
count
, context
, and colocated
are sorted based on the scopes in which they appear (loop, function, file).Suggestion selection
By default, VS Code pre-selects the previously used suggestion in the suggestion list. This is very useful as you can quickly insert the same completion multiple times. If you'd like different behavior, for example, always select the top item in the suggestion list, you can use the
editor.suggestSelection
setting.The available
editor.suggestSelection
values are:first
- Always select the top list item.recentlyUsed
- (default) The previously used item is selected unless a prefix (type to select) selects a different item.recentlyUsedByPrefix
- Select items based on previous prefixes that have completed those suggestions.
'Type to select' means that the current prefix (roughly the text left of the cursor) is used to filter and sort suggestions. When this happens and when its result differs from the result of
recentlyUsed
it will be given precedence.When using the last option,
recentlyUsedByPrefix
, VS Code remembers which item was selected for a specific prefix (partial text). For example, if you typed co
and then selected console
, the next time you typed co
, the suggestion console
would be pre-selected. This lets you quickly map various prefixes to different suggestions, for example co
-> console
and con
-> const
.Snippets in suggestions
By default, VS Code shows snippets and completion proposals in one widget. You can control the behavior with the
editor.snippetSuggestions
setting. To remove snippets from the suggestions widget, set the value to 'none'
. If you'd like to see snippets, you can specify the order relative to suggestions; at the top ('top'
), at the bottom ('bottom'
), or inline ordered alphabetically ('inline'
). The default is 'inline'
.Key bindings
The key bindings shown below are the default key bindings. You can change these in your
keybindings.json
file as described in Key Bindings.Note: There are many more key bindings relating to IntelliSense. Open the Default Keyboard Shortcuts (File > Preferences > Keyboard Shortcuts) and search for 'suggest'.
Troubleshooting
If you find IntelliSense has stopped working, the language service may not be running. Try restarting VS Code and this should solve the issue. If you are still missing IntelliSense features after installing a language extension, open an issue in the repository of the language extension.
Tip: For configuring and troubleshooting JavaScript IntelliSense, see the JavaScript documentation.
A particular language extension may not support all the VS Code IntelliSense features. Review the extension's README to find out what is supported. If you think there are issues with a language extension, you can usually find the issue repository for an extension through the VS Code Marketplace. Navigate to the extension's detail page and click the
Support
link.Next steps

Common questions
Why am I not getting any suggestions?
This can be caused by a variety of reasons. First, try restarting VS Code. If the problem persists, consult the language extension's documentation. For JavaScript specific troubleshooting, please see the JavaScript language topic.
Why am I not seeing method and variable suggestions?
This issue is caused by missing type declaration (typings) files in JavaScript. You can check if a type declaration file package is available for a specific library by using the TypeSearch site. There is more information about this issue in the JavaScript language topic. For other languages, please consult the extension's documentation.

React is a popular JavaScript library developed by Facebook for building web application user interfaces. The Visual Studio Code editor supports React.js IntelliSense and code navigation out of the box.
Welcome to React
We'll be using the
create-react-app
generator for this tutorial. To use the generator as well as run the React application server, you'll need Node.js JavaScript runtime and npm (Node.js package manager) installed. npm is included with Node.js which you can download and install from Node.js downloads.Tip: To test that you have Node.js and npm correctly installed on your machine, you can type
node --version
and npm --version
in a terminal or command prompt.You can now create a new React application by typing:
where
my-app
is the name of the folder for your application. This may take a few minutes to create the React application and install its dependencies.Note: If you've previously installed
create-react-app
globally via npm install -g create-react-app
, we recommend you uninstall the package using npm uninstall -g create-react-app
to ensure that npx always uses the latest version.Let's quickly run our React application by navigating to the new folder and typing
npm start
to start the web server and open the application in a browser:You should see the React logo and a link to 'Learn React' on http://localhost:3000 in your browser. We'll leave the web server running while we look at the application with VS Code.
To open your React application in VS Code, open another terminal or command prompt window, navigate to the
my-app
folder and type code .
:Markdown preview
In the File Explorer, one file you'll see is the application
README.md
Markdown file. This has lots of great information about the application and React in general. A nice way to review the README is by using the VS Code Markdown Preview. You can open the preview in either the current editor group (Markdown: Open Preview⇧⌘V (Windows, Linux Ctrl+Shift+V)) or in a new editor group to the side (Markdown: Open Preview to the Side⌘K V (Windows, Linux Ctrl+K V)). You'll get nice formatting, hyperlink navigation to headers, and syntax highlighting in code blocks.Syntax highlighting and bracket matching
Now expand the
src
folder and select the index.js
file. You'll notice that VS Code has syntax highlighting for the various source code elements and, if you put the cursor on a parenthesis, the matching bracket is also selected.IntelliSense
As you start typing in
index.js
, you'll see smart suggestions or completions.After you select a suggestion and type
.
, you see the types and methods on the object through IntelliSense.VS Code uses the TypeScript language service for its JavaScript code intelligence and it has a feature called Automatic Type Acquisition (ATA). ATA pulls down the npm Type Declaration files (
*.d.ts
) for the npm modules referenced in the package.json
.If you select a method, you'll also get parameter help:
Go to Definition, Peek definition
Through the TypeScript language service, VS Code can also provide type definition information in the editor through Go to Definition (F12) or Peek Definition (⌥F12 (Windows Alt+F12, Linux Ctrl+Shift+F10)). Put the cursor over the
App
, right click and select Peek Definition. A Peek window will open showing the App
definition from App.js
.Press Escape to close the Peek window.
Hello World!
Let's update the sample application to 'Hello World!'. Create a new H1 header with 'Hello, world!' and replace the
<App />
tag in ReactDOM.render
with element
.Once you save the
index.js
file, the running instance of the server will update the web page and you'll see 'Hello World!' when you refresh your browser.Tip: VS Code supports Auto Save, which by default saves your files after a delay. Check the Auto Save option in the File menu to turn on Auto Save or directly configure the
files.autoSave
user setting.Debugging React
To debug the client side React code, we'll need to install the Debugger for Chrome extension.
Note: This tutorial assumes you have the Chrome browser installed. There are also debugger extensions for the Edge and Firefox browsers.
Open the Extensions view (⇧⌘X (Windows, Linux Ctrl+Shift+X)) and type 'chrome' in the search box. You'll see several extensions which reference Chrome.
Press the Install button for Debugger for Chrome.
Set a breakpoint
To set a breakpoint in
index.js
, click on the gutter to the left of the line numbers. This will set a breakpoint which will be visible as a red circle.Configure the Chrome debugger
We need to initially configure the debugger. To do so, go to the Run view (⇧⌘D (Windows, Linux Ctrl+Shift+D)) and click create a launch.json file to customize Run and Debug. Choose Chrome from the Select Environment dropdown list. This will create a
launch.json
file in a new .vscode
folder in your project which includes a configuration to launch the website.We need to make one change for our example: change the port of the
url
from 8080
to 3000
. Your launch.json
should look like this:Ensure that your development server is running (
npm start
). Then press F5 or the green arrow to launch the debugger and open a new browser instance. The source code where the breakpoint is set runs on startup before the debugger was attached, so we won't hit the breakpoint until we refresh the web page. Refresh the page and you should hit your breakpoint.You can step through your source code (F10), inspect variables such as
element
, and see the call stack of the client side React application.The Debugger for Chrome extension README has lots of information on other configurations, working with sourcemaps, and troubleshooting. You can review it directly within VS Code from the Extensions view by clicking on the extension item and opening the Details view.
Live editing and debugging
If you are using webpack together with your React app, you can have a more efficient workflow by taking advantage of webpack's HMR mechanism which enables you to have live editing and debugging directly from VS Code. You can learn more in this Live edit and debug your React apps directly from VS Code blog post and the webpack Hot Module Replacement documentation.
Linting
Linters analyze your source code and can warn you about potential problems before you run your application. The JavaScript language services included with VS Code has syntax error checking support by default, which you can see in action in the Problems panel (View > Problems⇧⌘M (Windows, Linux Ctrl+Shift+M)).
Try making a small error in your React source code and you'll see a red squiggle and an error in the Problems panel.
Linters can provide more sophisticated analysis, enforcing coding conventions and detecting anti-patterns. A popular JavaScript linter is ESLint. ESLint, when combined with the ESLint VS Code extension, provides a great in-product linting experience.
First, install the ESLint command-line tool:
Visual Studio Bootstrap Templates
Then install the ESLint extension by going to the Extensions view and typing 'eslint'.
Once the ESLint extension is installed and VS Code reloaded, you'll want to create an ESLint configuration file,
.eslintrc.js
. You can create one using the extension's ESLint: Create ESLint configuration command from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)).Css Intellisense Visual Studio Code Not Working
The command will prompt you to answer a series of questions in the Terminal panel. Take the defaults, and it will create a
.eslintrc.js
file in your project root that looks something like this:ESLint will now analyze open files and shows a warning in
index.js
about 'App' being defined but never used.You can modify the ESLint rules in the
.eslintrc.js
file.Let's add an error rule for extra semi-colons:
Now when you mistakenly have multiple semicolons on a line, you'll see an error (red squiggle) in the editor and error entry in the Problems panel.
Popular Starter Kits
In this tutorial, we used the
create-react-app
generator to create a simple React application. There are lots of great samples and starter kits available to help build your first React application.![Code Code](/uploads/1/3/4/8/134823867/187823503.png)
VS Code React Sample
This is a sample React application used for a demo at the 2016 //Build conference. The sample creates a simple TODO application and includes the source code for a Node.js Express server. It also shows how to use the Babel ES6 transpiler and then use webpack to bundle the site assets.
TypeScript React
If you're curious about TypeScript and React, you can also create a TypeScript version of the
create-react-app
application by specifying that you want to use the TypeScript template:Bootstrap Intellisense Visual Studio Code 2019
See the details at Adding TypeScript on the Create React App site.
Using Bootstrap In Visual Studio
Angular
Angular is another popular web framework. If you'd like to see an example of Angular working with VS Code, check out the Chrome Debugging with Angular CLI recipe. It will walk you through creating an Angular application and configuring the
launch.json
file for the Debugger for Chrome extension.Common questions
Can I get IntelliSense within declarative JSX?
Yes. For example, if you open the
create-react-app
project's App.js
file, you can see IntelliSense within the React JSX in the render()
method.
