I'm gonna start this article by mentioning this great article by
So this example will be more or less the same but, instead return a simple Yey! string, we will fetch DEV's API to get my personal data.
DEV's endpoints are listed here.
I'm gonna call my file as DEV_profile.js and inside I'll put this:
const https = require("https");
const options = {
hostname: 'dev.to',
path: '/api/users/me',
headers: { 'api-key': 'YOUR_AMAZING_TOKEN' }
}
const getProfile = (event, context, callback) => {
// Just a guard to prevent other verbs
if (event.httpMethod !== 'GET') return
const req = https.request(options, res => {
let content = ''
res.setEncoding("utf8");
res.on('data', data => (content += data));
res.on('end',
body => callback(null, { statusCode: 200, body: content })
);
})
req.on('error', error => console.error(error))
req.end();
};
module.exports = { handler: getProfile }
Disclaimer: I'm not a backend developer so I'm not sure what I'm doing 🤪 but to handle CORS issues I'm gonna adding some lines to end of the file:
const middy = require('@middy/core')
const cors = require('@middy/http-cors')
/**
* Let's "middyfy" our handler, then we will be able to attach middlewares to it
* and Adds CORS headers to responses
*/
const handler = middy(getProfile).use(cors())
module.exports = { handler }
Following this article helped me a lot during development.
Finally you can watch the result here.
That's all 👋 👋
