装太多插件会影响性能吗？

会。建议只安装常用的 15-20 个插件，按项目启用/禁用，定期清理不用的插件。

Cursor 能用 VS Code 的插件吗？

可以。Cursor 基于 VS Code Fork，完全兼容 VS Code 插件生态。

VS Code Extensions

The funny thing about VS Code is that it gets better very quickly, and then, if you are not careful, it gets worse just as quickly. A few extensions can make the editor feel sharp and helpful. Too many, though, and suddenly everything is noisier, slower, and a little less predictable than it used to be.

#How to choose extensions without making a mess

The easiest way to stay sane is to think in layers:

core productivity
language and stack support
optional workflow tools

If an extension is not solving a real recurring annoyance, it probably does not need to be there.

#A sensible core set

#GitHub Copilot or another AI coding tool

Pick one primary AI workflow before you start stacking assistants on top of each other.

Common options:

GitHub Copilot
a Cursor-style workflow outside plain VS Code
one dedicated AI chat or edit tool

Too many overlapping AI extensions usually create noise, not leverage.

#Prettier

Formatting should be boring. Prettier keeps it that way.

#ESLint

Still one of the highest-value extensions for JavaScript and TypeScript work.

#Error Lens

Useful if you want problems surfaced inline instead of hidden in a panel.

#GitLens

Helpful when you need blame, history, and context without leaving the editor.

#Good VS Code extensions for frontend work

For React, Next.js, and TypeScript work, a good default set is:

ESLint
Prettier
Tailwind CSS IntelliSense
styled-components or CSS-in-JS support if the project uses it
import and path helpers when the repo structure gets large

#Good VS Code extensions for backend work

For Node, NestJS, and API-heavy work:

ESLint
Prettier
REST Client, if you test HTTP flows inside VS Code
Docker support, if you run services locally
.env helpers, if the project has a lot of environment config

#VS Code extensions for Python and data work

For Python and analysis workflows:

Python
Jupyter
lightweight data preview tools when you genuinely need them

Just do not turn VS Code into a notebook-heavy environment if notebooks are only an occasional task.

#Extensions to be careful with

#Too many AI assistants

Running multiple completion and chat tools at once often makes suggestions worse, not better.

#Heavy UI customization packs

Themes and icon packs are fine. Full-blown visual customization suites usually add more drag than value.

#Low-trust utility extensions

Extensions can read files, run code, and alter your workflow. Install them as if they were software, not stickers.

#Workspace configuration matters more than people think

Extensions become much more useful when the project also defines:

format-on-save rules
lint configuration
a default formatter
the TypeScript SDK path
test and task shortcuts

A disciplined workspace setup will beat a random pile of extensions every time.

#AI coding in VS Code

#Copilot

Best if you want familiar inline assistance without changing editors.

#Agent-first tools

Tools like Cursor or Windsurf can be stronger for larger tasks, but they change the workflow more substantially and may sit outside plain VS Code.

If your team standardizes on VS Code, choose the AI layer deliberately rather than letting every developer improvise a different setup.

#Bottom line

The best VS Code setup is boring in the right way: fast, stable, and easy to reason about. Start with formatter, linter, git visibility, and one clear AI workflow. Add more only when the need shows up repeatedly in real work.
