I often see students complaining about Nodedebugging troubles or not knowing how to debug various scripts, Jestetc. Webpack, and the articles related to debugging that I occasionally see are all written inspect. launch.jsonThese solutions actually have a certain learning cost.
In fact, a VSCoderather brainless Debugmethod has already been built in, that is , to use it, we only need to be responsible for the interrupt point, and we don’t need to pay attention JavaScript Debug Terminalto anything else . The main thing is a brainless and simple.inspectlaunch.json
use
The process of enabling JavaScript Debug Terminalis really mindless, but let's talk about it, it only takes one step to enable it: open Terminala new one in JavaScript Debug Terminaland then use it to start all scripts.
combat test
There is no evidence for empty talk, let's test how easy it is to use through a few cases.
node script
First, we create a test.jsscript, then click to add a breakpoint in front of the number of lines that need to be debugged, and enter Debug TerminalPass node test.jsto execute.
VSCodeIt can be seen that the mode is opened directly after execution debug, and it successfully stops at the breakpoint.
npm script
Let's try npm scriptthe method again, let's create a new one first package.json, then scriptsadd an item in : "start": "node test.js", and then Debug Terminalexecute it in npm run start.
Note that this time we are using debuggerto add a breakpoint, and we can find that the breakpoint is also entered successfully.
typescript debug
不止于此，我们再试试 typescript，新建一个 test.ts，然后通过 npx tsx test.ts 启动。
可以发现 typescript 一样可以成功调试。
webpack
上面都属于比较简单的场景，实际场景我们可能经常会在打包或写单测时遇到一些问题需要调试。现在我们先来随便找个 webpack 模版试试 webpack。
可以看到在 webpack 源码中打断点同样也可以支持。
jest
再来试试 jest，随便拿 react 源码里的单测跑一下。
不出所料，毫无问题。
其他方式
除了上面说的主动打开 Debug Terminal 的方式进行调试外，VSCode 还在 npm script 中集成了一些操作。
比如在 package.json 中的 scripts 上方的 Debug 按钮，点击后会让你选择项目中的 script 并启动 Debug Terminal 进行调试。
也可以在某个 script 的名字上 hover 后点击出现的悬浮按钮中的 Debug 直接调试对应的 script。
总结
可以看出 VSCode 的 JS Debug Terminal 基本支持了所有我们常用的调试场景，无论是 node、typescript、webpack 还是 jest，全部拿捏。并且使用绝对无脑，可以放心食用。
Of course, there are some small problems encountered in the process of use. For example, when running, jestbecause multiple sub-processes will be started, clicking disconnect in the breakpoint tool bar may cause Debug Terminalsubsequent failures and sometimes get stuck. However, the flaws do not conceal the advantages, and you will know that it is really fragrant after using it JS Debug Terminal.
