so i've been trying to understand something with this. until now i could post images, but now i would like to add PDF's aswell. i don't get if i can just add 'pdf' to my content Type or if i have to do another new config?
import AWS from "aws-sdk";
const s3 = new AWS.S3({
accessKeyId: process.env.S3_ACCESS_KEY,
secretAccessKey: process.env.S3_SECRET_KEY,
});
const buildObject = (key: string, body: string) => {
return {
Bucket: process.env.S3_BUCKET_NAME,
Key: `${key}`,
Body: body,
ACL: "public-read",
ContentEncoding: "base64",
ContentType: "image/jpeg",
};
};
export const upload = (fileData: string, options = { type: null }) => {
let { type = "image/png" } = options;
if (fileData.includes("base64") || !options.type) type = "image/jpeg";
const file = `${new Date().getTime()}.${type.split("/")[1]}`;
const object = buildObject(file, fileData);
return new Promise((resolve, reject) => {
s3.upload(object, (err, data) => {
if (err) reject(err);
else resolve(data.Location);
});
});
};
I believe you should use the Content-Type: "application/pdf".
I would advise using one lambda for images and another for pdfs to give it single responsibility.
You will need one type of request for images and another for pdfs.
the end result after many days of searching, it worked:
export const uploadFileForTechnialReport = async (req, res) => {
const { file } = req.files;
const { mimetype } = file;
const allowedTypes = ["jpeg", "jpg", "pdf"];
try {
if (!allowedTypes.some(type => mimetype.includes(type))) {
return res.status(422).jsonp("Invalid format try with jpeg, jpg or PDF");
}
let url;
console.log("start uploading to s3");
switch (mimetype.split("/")[1]) {
case "pdf":
url = await uploadPDF(file.data);
break;
default:
url = await upload(file.data);
break;
}
console.log("upload to s3 done");
return res.status(200).send(url);
} catch (err) {
return res.status(400).send(`AN_ERROR_OCCURED_${err}`);
}
};

const object = buildObject(file, fileData);

export const uploadPDF = async (fileData: string, options = { type: null }) => {
