如何在Express中更改默认的lib路径? [英] how to change the default lib path in Express?

问题描述

例如，有路径

/www/node/node_project/public/lib

/www/node/node_project/public/lib

我想将/public/lib移至/lib，但保持node_project运行；因为/lib文件夹与其他项目(可能是PHP项目)共享前端库；那么我该如何移动lib文件夹?！

I want to move /public/lib to /lib, but keep the node_project running; since /lib folder are share front-end libraries with other project (PHP projects maybe); so how can I move the lib folder around?!

推荐答案

您可以将Express静态根文件夹设置为:

You can set the Express static root folder as:

var app = require('express')();
var port = 3000 //The port on which your server listens
app.use(express.static('path to lib folder');
app.listen(port);

如果要指定特定于lib文件夹的路由，则可以将其设置为 app.use(express.static('/your/route'，lib文件夹的路径');

If you want to specify a route specific to the lib folder then you can set it as app.use(express.static('/your/route', path to lib folder');

如果您的lib文件夹与初始化express的文件位于同一文件夹，那么您只需提供 app.use(express.static('lib');

If your lib folder is on the same folder as the file that initializes express then you can simply give app.use(express.static('lib');

如果您的 lib文件夹是用于初始化express的文件夹的子文件夹，则可以使用 app.use(express.static(__ dirname +'lib的路径');

If your lib folder is a sub-folder of the folder in which express is initialized then you can use app.use(express.static(__dirname+'path to lib');

如果您的lib文件夹位于任何其他位置，请指定lib文件夹的绝对路径，例如 app.use(express.static('从/到lib的路径);

If your lib folder is on any other location then specify the absolute path to the lib folder like app.use(express.static('path to lib from /');
