提供静态文件的openshift express应用

Question

Noob here. I'm trying to build an api server on Openshift using express. I also want to be able to serve static files from the /static folder. The problem is, I can't figure out how to set it up on Openshift. I've tried everything I can think of.

I have 2 server files, the app setup which calls a router.js file for the routes.

app.js

    const express = require('express');
    const http = require('http');
    const bodyParser = require('body-parser');
    const morgan = require('morgan');
    const env = process.env;
    const app = express();
    const router = require('./router');
    const mongoose = require('mongoose');
    const cors = require('cors');


    // DB Setup
    // default to a 'localhost' configuration:
    var connection_string = '127.0.0.1:27017/api:api';
    // if OPENSHIFT env variables are present, use the available connection info:
    if(env.OPENSHIFT_MONGODB_DB_PASSWORD){
      connection_string = env.OPENSHIFT_MONGODB_DB_USERNAME + ":" +
      env.OPENSHIFT_MONGODB_DB_PASSWORD + "@" +
      env.OPENSHIFT_MONGODB_DB_HOST + ':' +
      env.OPENSHIFT_MONGODB_DB_PORT + '/' +
      env.OPENSHIFT_APP_NAME;
    }
    mongoose.connect('mongodb://' + connection_string);


    // App Setup
    app.use(morgan('combined')); //logging middleware
    app.use(cors()); // allow cross origin requests
    app.use(bodyParser.json({ type: '*/*'}));  //read requests as json

 ----->  do I need to put something here ????

    router(app);


    // Server Setup
    const port = env.NODE_PORT || 3090;
    const ip = env.NODE_IP || 'localhost';
    const server = http.createServer(app);
    server.listen(port, ip);
    console.log('Server listening on: ', port);

router.js

const Authentication = require('./controllers/authentication');
const passportService = require('./services/passport');
const passport = require('passport');
const requireAuth = passport.authenticate('jwt', { session: false});
const requireSignin = passport.authenticate('local', { session: false});

module.exports = function(app) {

 app.post('/signup', Authentication.signup);
 app.post('/signin', requireSignin, Authentication.signin);

 app.get('/health', function (req, res, next ) {
      res.writeHead(200);
    res.end();
 });

 ---->  and/or something here?
}

Everything works except serving static files. Not sure if I need to put something in the app.js file as middleware, in the router file or both. Also not sure if I need to use Openshift environment variables? Can someone nudge me in the right direction?

Answer 1

In express you can serve static files by adding the following to your app.js using express.static()

var path = require('path');

// put this before all of your routes
app.use(express.static(path.join(__dirname, 'static')));
