Unable to render JSON in html - node.js
Question
This is probably a simple solution, however I cannot figure out how to carry my JSON object over to my view. Normally you'd throw JSON into res.render() inside your app.get .. unfortunately I am having trouble. A problem arises because i need to be able to send form data from html to my API request, then grab that JSON object and display it in my view. I can see it in my console, but unable to carry it over to html. Would love some help or guidance on how to improve my code or find a solution. Any help is appreciated! - View code below:
Server.js
var path = require('path');
var express = require('express');
var exphbs = require('express-handlebars');
var bodyParser = require('body-parser');
var Bls2 = require('bls2');
var app = express();
app.engine('html', exphbs({ extname: '.html' }));
app.set('view engine', 'html');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
var blsRequest = function(req, res, inputContent){
const API_KEY = //bls API key here
let bls = new Bls2(API_KEY);
console.log('this is seriesID =', inputContent);
let options = {
'seriesid': [inputContent],
'startyear': '2008',
'endyear': '2018',
// ...
};
bls.fetch(options).then(function (response) {
var data = JSON.stringify(response)
console.log(data);
console.log('API Call Complete')
res.send({data : data}); //need to render home view and JSON HERE
});
}
app.get('/', function (req, res) {
res.render('home');
});
app.post('/', function(req, res){
let inputContent = req.body.seriesID;
blsRequest(req, res, inputContent);
});
app.listen(8000);

<input type="text" class="form-control" name="seriesID" placeholder="Series ID">

<button class="btn btn-primary" type="submit" >Search</button>
</form><br>
uhh JSON should be here: {{data}}
</div>
</body>
<script type="text/javascript">
$("#seriesID").submit(function (event) {
$.post('/', $("#seriesID").serialize(), function (data) {
//data is the response from the backend
});
event.preventDefault();
});
</script>
</html>

use res.render('home',{data}); because your {{data}} is undefined that's why it is not printing anything it is even better to use {{JSON.stringify(data)}}
