Usage

import { findNodeByKey } from "tree-handle-lib";
// or use `const { findNodeByKey } = require('tree-handle-lib/dist/index.cjs.js')` as commonjs
const tree = [
      {
        id: '1',
        name: 'www',
        children: [],
      },
    ];
const node = findNodeByKey(tree, '1', "children", 'id');

Can also import like

import treeHandleLib from "tree-handle-lib";

console.log(treeHandleLib.findNodeByKey); // Function

or like this, import from a child package

import {findNodeByKey} from "tree-handle-lib/dist/find.js";

console.log(findNodeByKey); // Function

Developer Compatibility

Developer Guide

1. create a module and file under src/lib directory.
2. create a tree handle function and export it by default.
3. add test unit in ./test directory.
4. pnpm run build or pnpm run test. so that you can see there is an additional file has been added to the tmp directory and some changed in babel.config.cjs
5. you can only test the module you want, by edit jest.testMatch in package.json.
6. publish npm package. first using the pnpm version patch command, push the code to github, and create a release on github. it can auto publish package to npm.

TODO

1. Realize the pure function form of implementing the method.
2. Build only the modules you are developing
3. Develop a scaffolding for automatically generating method modules and test samples
