First of all, if you haven't added updatedfields to the article before, you need to add them first.
updated1. Add fields to existing articles
If your existing article already has an updated field, this step can be skipped.
Code reference: Batch write the modification time of files . Originally, only files in the same directory can be accessed. I added it to allow access to all files (including subfolders).
Create a js file: 博客根目录/source/_posts/writeupdatetime.js, the content of the file is as follows
#!/usr/bin/env node
/*
批量添加修改时间
用于bolg初始化修改时间
*/
console.log('脚本开始运行..');
var fs = require("fs"); //请求文件系统
var file = "./txt"; //设置读取和写入的文件，当前目录下的test文件
var RegExp=/(updated:\s*)((\d{2}(([02468][048])|([13579][26]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|([1-2][0-9])))))|(\d{2}(([02468][1235679])|([13579][01345789]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|(1[0-9])|(2[0-8]))))))(\s((([0-1][0-9])|(2?[0-3]))\:([0-5]?[0-9])((\s)|(\:([0-5]?[0-9])))))/g;

}After 博客根目录/source/_posts/opening bash, run the code:
./writeupdatetime.jsThe code works by looking for categories, categoriesadding updatedfields above fields, so make sure you do that for each post categories. If it is not added, please modify the source code by yourself and categorieschange it to other fields, such as tagsetc.
Open your articles and take a look to make sure each article is added updated.
2. Modify the Front-matter template
Open 博客根目录/scaffolds/post.mdthe file, modify the added updatedfields, take my template as an example:
title: {
{ title }}
date: {
{ date }}
updated: {
{ date }}
mathjax: false
mermaid: false
summary: 啥都没写，别看了hexo new postThere will be fields when you create a new article in the future updated.
3. Code realizes automatic update of article modification time
Code reference: Automatically update the modification time of the article , and make some changes to enable it to search all files (including subdirectories).

#!/usr/bin/env node
