Right now I am editing the code inline on AWS lambda. This is what I have currently:
var qrImage = require('qr-image');
exports.handler = async (event) => {
return sendRes(200,'hi');
};
/*
const sendRes = (status, body) => {
var response = {
statusCode: status,
headers: {
"Content-Type": "text/html"
},
body: body
};
return response;
};
*/
const sendRes = (status, body) => {
const svg_string = qrImage.imageSync('http://www.nodejs.org',{ type: 'png', size: 20 });
var response = {
statusCode: status,
headers: {
"Content-Type": "image/jpeg"
},
body: svg_string
};
return response;
};
This outputs the text Internal server error.
The code below creates a png file and stores it. The functionality I would like on lambda is to simply display the image(No saving involved) when I access the endpoint. But I am not sure how to go about it (New to Lamda, Node.js). What exactly should I be looking into?
var qrImage = require('qr-image');
var fs = require('fs');
qrImage
.image("http://www.nodejs.org", {type:'png', size:20})
.pipe(fs.createWriteStream("MyQRCode.png"));
EDIT I made some small changes and this appears to be working
var qrImage = require('qr-image');
exports.handler = async (event) => {
return sendRes(200,'hi');
};
const sendRes = (status, body) => {
const svg_string = qrImage.imageSync('this is AWS!', { type: 'svg', size: 10 });
var response = {
statusCode: status,
headers: {
"Content-Type": "image/svg+xml"
},
body: svg_string
};
return response;
};

If you are only returning the image with the help of lambda then sync will also work, here the code for it
const sendRes = (status, body) => {
const svg_string = qr.imageSync('http://www.nodejs.org', { type: 'png', size: 20 });
var response = {
statusCode: status,
headers: {
"Content-Type": "image/jpeg"
},
body: svg_string
};
return response;
};
