visit with typescript - test for leteral

[PhilipBrodovsky]

     unified()
     .use(() => (tree, f) => {
          visit(tree, "text", (node) => {
              node.value;
          });
      })

how to add types to this code?

I want to visit all Literal nodes and get text value

Type your plugin. E.g. https://github.com/retextjs/retext-readability/blob/fc84a20faf4e85efa471a788942d3c9195956e82/index.js#L49

didnt help..

@PhilipBrodovsky If you are using TypeScript as JS files with JSDoc comments for types, the above, works.
If you are using .ts files and annotations, use a type annotation.

yes i use .ts file
I started to use unified today, and I see a lot of plugins,
I cant figure out how type system work..
and I use typescript project..

import { unified, Plugin } from "unified";
import remarkParse, { Options } from "remark-parse";
import { visit } from "unist-util-visit";
import { Root } from "remark-parse/lib";

const myPlugin: Plugin<[Options?], Root> = () => {
    return (tree) => {
        console.log(tree);

        visit(tree, "text", function (node) {
            console.log("text", node.value);
        });
    };
};

its look like this code solve my problem..
I am not sure if I do it right

It would be better to import Root from mdast (@types/mdast).

Otherwise this looks correct 👍
