So, let's say i have /api/cat/fact.js directory.
I wanna to get JSON Data from catfact.ninja
The thing is, i can't use require() or request() package, because if i used require, it would saya Couldnt Found Module..., and if i used request one, instead of returning the JSON Data that you beable to sees in catfact.ninja, it return JSON about the api, like hostname, port, which is i don't need
/API/api/cat/fact.js:
const express = require('express');
const app = express.Router();
const request = require('request')
app.use('', (req, res) => {
const src = 'https://catfact.ninja/fact';
const facts = request({
uri: src,
hostname: 'catfact.ninja',
port: 443,
path: '/fact',
method: 'POST',
json: 'fact'
}, (error, response, body) => {
if (error) console.log(error)
console.log(body, '\n\n' + response.fact)
})
console.log(facts);
return res.jsonp(facts)
})
module.exports = app;
You are returning JSON in the wrong place. It should be returned inside of the callback function.
Here's the solution:
const express = require('express');
const request = require('request-promise')
const app = express();
app.use('', async (req, res) => {
const src = 'https://catfact.ninja/fact';
try {
const response = await request({
uri: src,
port: 443,
method: 'GET',
json: true
})
return res.jsonp(response)
} catch (err) {
return res.jsonp(err)
}
})
function startServer() {
const port = 3000
app.listen(port, () => {
console.info('Server is up on port ' + port)
})
app.on('error', (err) => {
console.error(err)
process.exit(1)
})
}
startServer()
TIP: I suggest using request-promise npm package instead of request package as it provides async-await approach, which is cleaner. Else, you can continue using callback function as second request() function parameter.
