egret 白鹭的编译太慢了 自己写了一个

用的swc
他会检测git的改变

const simpleGit = require('simple-git');
const fs = require('fs');
const path = require('path');
// 初始化 simple-git
const swc = require('@swc/core');
const baseDir = 'D:\\project';
const gameDir = 'game\\module\\abcdefg';
const gitDir = 'D:\\project';
const git = simpleGit(gitDir);
const crypto = require('crypto');

        const changedFiles = [
            ...statusSummary.modified,
            ...statusSummary.created,
            ...statusSummary.not_added
        ];
        const changedTsFiles = changedFiles.filter(file => file.endsWith('.ts'));
        if (changedTsFiles.length > 0) {

            });
        }
    } catch (error) {
