The source(`.tsx file`) in Emacs before:

    import React from "react";

    export default {
      ...
      args: {
        name: "",  // Here
      },
      decorators,
    };

The source in Emacs after:

    import React from "react";

    export default {
      ...
      args: {
          name: "Awesome",  // Here
      },
      decorators,
    };

I copied an `Awesome` text from other place and paste it to the
editor, the indent changed from 2 to 4 at that line. Why it changed?
How to avoid it?

Are you using `web-mode`? It has pretty aggressive autoindentation
behavior.

Try customizing `web-mode-code-indent-offset` and `web-mode-markup-
indent-offset` to 2 or whatever fits your coding style.

Yes, I'm using `web-mode`. This is my config:

      (defun tide-setup-hook ()
        (tide-setup)
        (eldoc-mode)
        (tide-hl-identifier-mode +1)
        (setq web-mode-enable-auto-quoting nil)
        (setq web-mode-markup-indent-offset 2)
        (setq web-mode-code-indent-offset 2)
        (setq web-mode-attr-indent-offset 2)
        (setq web-mode-attr-value-indent-offset 2)
        (setq lsp-eslint-server-command '("node" (concat (getenv
"HOME") "/var/src/vscode-eslint/server/out/eslintServer.js") "--
stdio"))
        (set (make-local-variable 'company-backends)
        ┆   ┆'((company-tide company-files :with company-yasnippet)
        ┆   ┆  (company-dabbrev-code company-dabbrev))))

They are already been set to 2.

The configuration-layer:

    ┆(typescript :variables
    ┆   ┆   ┆   ┆javascript-backend 'tide
    ┆   ┆   ┆   ┆typescript-fmt-tool 'prettier
    ┆   ┆   ┆   ┆typescript-linter 'eslint
    ┆   ┆   ┆   ┆typescript-fmt-on-save t)

Then I’m out of ideas, you might need to dive into edebug to see what
variables are consulted.

Judging by you also pasting your indentation guides, are you using
Emacs in a terminal? Emacs might not be able to differentiate between
a user input and a paste when used this way.

Yes, I'm using emacs in a terminal. But even I use it in a GUI tool
still got the same issue.
