Errors thrown will be printed, rather than silently eaten.

Logpoint breakpoints now support complex expressions and statements.

Promises, ArrayViews/ArrayBuffers, and other complex data structures are better supported. Here are some more that are unworthy of their own heading: Js-debug is a cleanroom rewrite of a JavaScript debugger, so there are a large number of small improvements.

Changes in VS Code and js-debug allow us to losslessly copy the full expressions as JSON. However, previously this was truncated for object or long values. VS Code has long had an action to "Copy Value" from the Variables view.

We now support in-place transpilation (such as ts-node and values in call stack view.

This is common when dealing with split bundles in web apps.

We can handle sources present in multiple compiled files.

We are guaranteed to set breakpoints before hitting them, where there were previously scenarios where this did not happen.

This results in more reliable breakpoint behavior in more cases. Js-debug has a rewritten suite of sourcemap handling and breakpoint resolution logic.

Check out our webview demo to learn how to set this up.

With this comes support for the WebView2 control in desktop Windows applications. It supports all the same configuration settings as chrome does. We support launching the new Microsoft Edge browser, via the pwa-msedge debug type. You can turn off the suggestion prompt by selecting Never, or changing the setting to false. It will show a prompt when you step into or open a file that looks minified, and you can also trigger pretty printing manually via the Debug: Pretty print for debugging command. The debugger can now pretty print files, especially useful when dealing with minified sources. This is because the JavaScript event loop is paused while on a breakpoint. However, like the Chrome devtools, if you use await while paused on a breakpoint, you'll only get a pending Promise back. You can use await at the top level in the debug console. Note that you can use and modify properties on the $returnValue, but not assign it to-it is effectively a const variable. On a function's return statement, you can use, inspect, and modify the $returnValue.

You can expect better suggestions for more complex expressions than VS Code was able to handle before. Better autocompletion in debug consoleĪutocomplete in the debug console has been significantly improved. When debugging web apps, you can configure instrumentation breakpoints from VS Code in the "Browser Breakpoints" view. If you'd like, you can enable this for all terminals, or disable it, by setting to always or off, respectively. Automatic browser debuggingīy default, any links you click through the JavaScript debug terminal ( Debug: Create JavaScript Debug Terminal command) will open in debug mode. You can configure where and if the code lens is displayed in the setting. You can debug npm scripts by clicking the code lens shown in the package.json, or by running the Debug: Debug NPM Script command/ The profile information collected through VS Code is sourcemap-aware. You can capture and view performance profiles natively in VS Code, by clicking on the ⚪ button in the Call Stack view, or through the Debug: Take Performance Profile command. In the previous debugger, you had to remember to add the -inspect flag when you ran a command, and couldn't hit breakpoints early in the program since attachment was asynchronous. You can also create a one-off terminal for debugging via the Debug: Create JavaScript Debug Terminal command. Once enabled, you can toggle Auto Attach by clicking the Auto Attach: On/Off button in the status bar on the bottom of your screen. Next time you run a command like npm start, we'll debug it.

If auto attach isn't on, you can run the command Debug: Toggle Auto Attach to turn it on. You can debug any Node.js process you run in the terminal with our revamped Auto Attach. While debugging workers, you can also step through postMessage() calls. In browsers, service workers, webworkers, and iframes will be debugged as well. In Node.js, child processes will automatically be debugged. Here are a few new features that js-debug brings: Debug child process and workers In js-debug we aim to provide rich debugging for modern applications, with no or minimal configuration required.

Open the extensions view (ctrl+shift+x) and search for Right click on the JavaScript Debugger extension and select Switch to Pre-Release Version.

The build runs at 5PM PST on each day that there are changes ( see pipeline).

The shipped version of VS Code includes the js-debug version at the time of its release, however you may want to install our pre-release build to get the latest fixes and features. It has been the default JavaScript debugger in Visual Studio Code since 1.46, and is gradually rolling out in Visual Studio proper. It debugs Node.js, Chrome, Edge, WebView2, VS Code extensions, and more.
