Question

节点非常新，请原谅基本问题。我已经看过以前的问题，但我仍然不确定如何自己解决这个问题。

我有一个运行的节点应用程序，它执行大量数据检索，调用外部REST API。我希望能够使用这些数据并在客户端使用d3等进行处理。

我的快递app.js：

def create(self, validated_data):
    validated_data['free_space'] = validated_data['size']
    return super(CreateDiskSerializer, self).create(validated_data)

然后我在express / public / javascripts

中有app.js.

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var stylus = require('stylus');

var index = require('./routes/index');
var users = require('./routes/users');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(stylus.middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', index);
app.use('/users', users);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});
module.exports = app;
// bunch of external api stuff
.
.
.

如何将数据从服务器端节点（express）传递到客户端脚本
