Q&A

What's the different Node version and Web version?

pinyin support Node and Web browser now, the API and usage is complete same.

But the Web version is simple than Node version. Just frequently-used dict, without segmentation, and the dict is compress for web.

Because of Traditional and Segmentation, the convert result will be not complete same. and the test case have some different too.

How to sort by pinyin?

This module provide default compare implementation:

const pinyin = require('pinyin');

const data = '我要排序'.split('');
const sortedData = data.sort(pinyin.compare);

But if you need different implementation, do it like:

const pinyin = require('pinyin');

const data = '我要排序'.split('');

// Suggest you to store pinyin result by data persistence.
const pinyinData = data.map(han => ({
  han: han,
  pinyin: pinyin(han)[0][0], // Choose you options and styles.
}));
const sortedData = pinyinData.sort((a, b) => {
  return a.pinyin.localeCompare(b.pinyin);
}).map(d => d.han);
