Electron多环境打包

正文

客户端打包的时候如果有不同的logo，名称等信息，每次打包都需要替换一遍 ，所以这里就写了个脚本来批量替换文件和文字。

替换文本和复制文件

const path = require("path");
const fs = require("fs");

const suff_arr = [".html", ".js", ".txt", ".vue", ".json"];

function changefile(mpath, oldword, newword) {
    let suff = mpath.substring(mpath.lastIndexOf("."));
    if (suff_arr.indexOf(suff) !== -1) {
        console.info("mpath", mpath);
        try {
            let files = fs.readFileSync(mpath, 'utf8')
            const result = files.replace(new RegExp(oldword, "g"), newword);
            fs.writeFileSync(mpath, result, 'utf8');
        } catch (e) {
            console.info(e);
        }
    }
}

function editKeyWord(mpath, oldword, newword) {
    var stat = fs.lstatSync(mpath);
    if (stat.isFile()) {
        changefile(mpath, oldword, newword);
    } else if (stat.isDirectory()) {
        try {
            let data = fs.readdirSync(mpath, 'utf8');
            if (data) {
                data.forEach(function (item, index) {
                    let temppath = path.join(mpath, item);
                    editKeyWord(temppath, oldword, newword);
                });
            }
        } catch (e) {
            console.info(e);
        }
    }
}


/*

 */
function copyDir(src, dist, err_callback) {
    try {
        fs.accessSync(dist);
        _copy(src, dist, err_callback);
    } catch (e) {
        fs.mkdirSync(dist);
    }
    
    function _copy(src, dist, err_callback) {
        try {
            let paths = fs.readdirSync(src);
            paths.forEach(function (mpath) {
                let _src = path.join(src, mpath);
                let _dist = path.join(dist, mpath);
                try {
                    let stat = fs.statSync(_src);
                    // 判断是文件还是目录
                    if (stat.isFile()) {
                        if (fs.existsSync(_dist)) {
                            fs.unlinkSync(_dist);
                        }
                        fs.writeFileSync(_dist, fs.readFileSync(_src));
                    } else if (stat.isDirectory()) {
                        // 当是目录是，递归复制
                        copyDir(_src, _dist, err_callback)
                    }
                } catch (e) {
                    err_callback(err);
                }
            })
        } catch (err) {
            err_callback(err)
        }
    }
}

exports.editKeyWord = editKeyWord;
exports.copyDir = copyDir;

注意

所有的文件操作，这里都用的同步。异步会导致，如果有多个同时进行的替换，就会文件占用导致替换失败。

保留上一次的文字_oldname.js

exports.oldname = "火星直播";

替换文字和文件

const {editKeyWord, copyDir} = require("./_common");
const path = require("path");

const {oldname} = require("./_oldname");
let newname = "星火直播测试";

const filePath = path.resolve(__dirname, '../src/');
editKeyWord(filePath, oldname, newname);

let html_arr = [
    "_package/_oldname.js",
    "main.js",
    "package.json",
    "v_blackboard.html",
    "v_class_center.html",
    "v_classtip.html",
    "v_device_test.html",
    "v_dianming.html",
    "v_exit_dialog.html",
    "v_home.html",
    "v_huamingce.html",
    "v_huamingce_mini.html",
    "v_jiangping.html",
    "v_login.html",
    "v_player_win.html",
    "v_qiangda.html",
    "v_space.html",
    "v_stu_head.html",
    "v_teacher_head.html",
    "v_test.html",
    "v_tip.html",
    "v_tiwen.html",
    "v_tongji.html",
    "v_tweb.html"
];

for (const str of html_arr) {
    const temppath = path.resolve(__dirname + '/../' + str);
    editKeyWord(temppath, oldname, newname);
}

const themepath = path.resolve(__dirname, '../src/config/Config.js');
editKeyWord(themepath, 'themename = "theme_red"', 'themename = "theme_blue"');

const path_origin = path.resolve(__dirname, './xh/image');
const path_target = path.resolve(__dirname, '../image');
copyDir(path_origin, path_target, function (err) {
    if (err) {
        console.log(err);
    }
})

const ico_origin = path.resolve(__dirname, './xh/ico/');
const ico_target = path.resolve(__dirname, '../');
copyDir(ico_origin, ico_target, function (err) {
    if (err) {
        console.log(err);
    }
})

方便执行我们写了批处理文件

test.bat

node test.js
