How To Install Sonarlint In Visual Studio

SonarLint for Visual Studio Code

SonarLint is a gratis IDE extension that lets you fix coding issues before they be! Similar a spell checker, SonarLint highlights Bugs and Security Vulnerabilities every bit you write code, with articulate remediation guidance so y'all can fix them before the code is fifty-fifty committed. SonarLint in VS Code supports analysis of JavaScript, TypeScript, Python, Coffee, HTML & PHP code, and you tin install information technology straight from the VS Code Marketplace!

How it works

Simply open up a JS, TS, Python, Java, HTML or PHP file, starting time coding, and you will start seeing issues reported past SonarLint. Issues are highlighted in your code, and also listed in the 'Bug' console.

Yous can access the detailed rule description directly from your editor, using the provided contextual menu.

Static Analysis Rules

Out of the box, SonarLint automatically checks your code against the post-obit rules:

JavaScript rules
TypeScript rules
Python rules
Coffee rules
HTML rules
PHP rules
Secrets rules

The full listing of available rules is visible in the "SonarLint Rules" view in the explorer, where you can activate and deactivate rules to match your conventions. SonarLint will also show a code action on each consequence to quickly conciliate the respective rule.

Requirements

The SonarLint language server needs a Java Runtime (JRE) eleven+. If one is already installed on your computer, SonarLint should automatically find and utilise it. Here is how SonarLint volition search for an installed JRE (in priority order):

the sonarlint.ls.javaHome variable in VS Code settings if ready. For instance:

{ "sonarlint.ls.javaHome": "C:\Programme Files\Java\jre-11.0.xi" }
the value of the JDK_HOME environment variable if fix
the value of the JAVA_HOME environment variable if set
on Windows the registry is queried
if a JRE is even so non institute then:
1. the PATH is scanned for javac
2. on macOS, the parent directory of javac is checked for a java_home binary. If that binary exists and so it is executed and the result is used
3. the grandparent directory of javac is used. This is like to $(dirname $(dirname $(readlink $(which javac))))

SonarLint then uses the starting time JRE found in these steps to check its version.

If a suitable JRE cannot be found at those places, SonarLint will ask for your permission to download and manage its ain version.

JS/TS analysis specific requirements

To analyze JavaScript and TypeScript code, SonarLint requires Node.js executable. It will be autodetected, or y'all can force the location using:

          {     "sonarlint.pathToNodeExecutable": "/abode/julien/.nvm/versions/node/v11.12.0/bin/node" }

Java assay specific requirements

To enable the support for Java analysis, you need the Language support for Coffee VSCode extension (version 0.56.0 or higher). You likewise demand to be in standard manner.

Apex assay specific requirements

The support for Apex assay is only bachelor together with SonarQube Enterprise Edition or SonarCloud (see connected way below). You also demand the Salesforce Extension Pack VSCode extension.

PL/SQL analysis specific requirements

The support for PL/SQL assay is only bachelor together with SonarQube Developer Edition or SonarCloud (see continued fashion below). You also demand the Oracle Developer Tools for VSCode extension.

Connected fashion

Y'all can connect SonarLint to SonarQube >= vii.9 or SonarCloud and demark your workspace folders to a SonarQube/SonarCloud project to benefit from the same rules and settings that are used to inspect your projection on the server. SonarLint then hides in VSCode the issues that are marked equally Won't Fix or False Positive.

Connected mode will as well permit to unlock analysis of those languages:

Apex rules
PL/SQL rules.

The first step is to configure connection details (user token, SonarQube server URL or SonarCloud organisation). For security reasons, the token should not be stored in SCM with workspace settings. That's why we suggest to configure them in VSCode user settings.

Example for SonarQube:

          {     "sonarlint.connectedMode.connections.sonarqube": [         { "serverUrl": "https://sonarqube.mycompany.com", "token": "<generated from SonarQube business relationship/security page>" }     ] }

Example for SonarCloud:

          {     "sonarlint.connectedMode.connections.sonarcloud": [         { "organizationKey": "myOrg", "token": "<generated from https://sonarcloud.io/business relationship/security/>" }     ] }

The 2d step is to configure the project binding, either at workspace level, or in every workspace folders. Example:

          {     "sonarlint.connectedMode.project": {         "projectKey": "the-project-key"     } }

If you program to use multiple connections, to dissimilar SonarQube servers and/or SonarCloud organizations, merely give a unique connectionId to each entry, and use them equally reference in the bounden.

Example:

          // In user settings {     "sonarlint.connectedMode.connections.sonarqube": [         { "connectionId": "mySonar", "serverUrl": "https://sonarqube.mycompany.com", "token": "xxx" }     ]     "sonarlint.connectedMode.connections.sonarcloud": [         { "connectionId": "myOrgOnSonarCloud", "organizationKey": "myOrg", "token": "yyy" }     ] }  // In project1/.vscode/settings.json {     "sonarlint.connectedMode.projection": {         "connectionId": "mySonar",         "projectKey": "the-project-key-on-sq"     } }  // In project2/.vscode/settings.json {     "sonarlint.connectedMode.project": {         "connectionId": "myOrgOnSonarCloud",         "projectKey": "the-project-key-on-sc"     } }

Configuring a project bounden at the workspace level mutes Won't Fix and False Positive issues in whatsoever of the project'southward sub-folders added to the workspace. SonarLint volition exercise its best to synchronize with the nigh appropriate branch from the server.

In connected way with SonarCloud or any commercial edition of SonarQube, SonarLint receives notifications about Quality Gate changes and new bug. This characteristic can be toggled using the disableNotifications field in a server connection definition.

When using SonarQube >= 8.vi and browsing a security hotspot at that place volition be a button offering to open the hotspot in SonarLint if you lot have already SonarLint running in VSCode. Limitation: this feature relies on local communication between your spider web browser and SonarLint, and consequently is not bachelor in CodeSpaces.

SonarLint keeps server side data in a local storage. If you change something on the server such equally the quality profile, you tin trigger an update of the local storage using the "SonarLint: Update all projection bindings to SonarQube/SonarCloud" control on the command palette (search for "sonarlint"). SonarLint will also automatically attempt to synchronize with configured servers at startup and every hour.

Contributions

If you lot would like to see a new feature, delight create a new thread in the forum "Suggest new features".

Delight be aware that we are not actively looking for feature contributions. The truth is that it's extremely hard for someone outside SonarSource to comply with our roadmap and expectations. Therefore, we typically but accept minor cosmetic changes and typo fixes.

With that in mind, if y'all would similar to submit a code contribution, please create a pull request for this repository. Delight explain your motives to contribute this modify: what problem you lot are trying to fix, what comeback you are trying to make.

Make certain that you follow our code mode and all tests are passing.

Take Question or Feedback?

For SonarLint support questions ("How do I?", "I got this error, why?", ...), please first read the FAQ and then head to the SonarSource forum. There are chances that a question similar to yours has already been answered.

Be aware that this forum is a customs, so the standard pleasantries ("Hi", "Thanks", ...) are expected. And if you don't get an answer to your thread, y'all should sit down on your hands for at least 3 days before bumping it. Operators are not standing by. :-)
