Enhanced TypeScript Support

Starting with 1.5.0 release, we've supported TypeScript.

We are happy to announce the support for 2.5, the latest stable version of TypeScript. We promised TypeScript 2.4 support earlier, but TypeScript is rapidly changing and we got 2.5 support on the way.

Introduced improvements are:

Support latest TypeScript language features including optional catch variables, dynamic import, for-await-of and generators
Better syntax error detections
Report only the first syntax error because other syntax errors are usually not meaningful

And, TypeScript-compiled files are automatically excluded.

New Rules

More React rules

The following new rules check React runtime errors or warnings. Check out here for full React specific rules.

BAD_INITIAL_STATE_TYPE - The initial state of React component should be set to an object
BAD_REACT_API_OVERRIDDEN - ES6 class component should not override getInitialState() and getDefaultProps()
BAD_REACT_SPECIAL_PROPS - Do not read ref and key special properties
BAD_REACT_STYLE_OBJ_PROPERTY - Property name or value of React DOM element's style object should be correct
DEPRECATED_REACT_DOM_ELEMENT_PROP - Do not use the deprecated prop for a React element
MISUSED_API_IN_RENDER - Do not use specific APIs inside render()
MISUSED_CREATOR_IN_PROP_TYPES - Do not use a type checker creator itself as a prop type
MISUSED_REACT_INNER_HTML - Do not use innerHTML prop for a React DOM element
MISUSED_UPDATE_IN_SET_STATE - Do not directly use this.state when updating the state in React component
REACT_STATIC_PROPERTY_IN_INSTANCE - Do not use propTypes and contextTypes static properties as an instance property

Improved Rules

UNREACHABLE_CODE

Detect unreachable break statement after return statement in the loop

CONSTANT_CONDITION

Fixed duplicate alarms on && and || expressions

Provide detailed alarm message when the cause is type annotation

Condition 'Array.isArray(className)' is always false at this point because the parameter 'className' is annotated as string type at line 25.

UNINITIALIZED_LOCAL_VAR

Filter-out alarms on common initialization checking pattern of x = x || foo()
Detect alarms on never initialized closure variables

UNUSED_VAR_ASSIGN

Detect alarms on never used closure variables

Node.js Package

It'll be easy to fix an issue once you see there's an issue before code ships.

So we hope that our tool can be used easily in the developer's hand. As part of the efforts, we implemented a Node.js package which enables you to see bugs and quality issues in the CLI (command-line interface) or by the programmatic API.

Using the results, you can inspect your project in the local PC and integrate with CI as you want.

Please check it out.

Note: Available only to partners.

History for Status Changes

Starting with 1.3.0 release, we've provided status management of an issue.

Now you can see your historical changes when and why you changed the status of an issue.

Additionally, you can add an optional comment when you change the status. Comment will be on the history also.

Status Changes

PNG Support for Badge

We encountered a problem when adding the badge to our Visual Studio Code extension. Publishing an extension with SVG file is not permitted due to security concerns.

Trying to register DeepScan as a trusted badge provider, now we provide PNG badge also. If you prefer a PNG than SVG file, just replace .svg in the badge url with .png.

Happy badging!

Miscellaneous

Introduce login page. You will be redirected if you have an authentication problem.
Preserve login state although a user goes back immediately after log-in.
Show a proper progress view although an analysis ends quickly.
Demo: Change language configuration on drag-and-drop in editor.
