POST File in AXIOS NodeJs - node.js

Question

Post file as raw body in AXIOS NodeJS. I tried many ways to achieve this but none of them worked.
What i have tried ?
var file = fs.readFileSync("a.jpg");
var body = await axios({ method: 'POST', url : "myUrl", data : file });
var file = fs.readFileSync("a.jpg").toString();
var body = await axios({ method: 'POST', url : "myUrl", data : file });
var file = fs.readFileSync("a.jpg",{encoding:"utf8"}).toString();
var body = await axios({ method: 'POST', url : "myUrl", data : file });
var file = fs.readFileSync("a.jpg");
file = Buffer.from(file).toString('utf8')
var body = await axios({ method: 'POST', url : "myUrl", data : file });
var file = fs.createReadStream("a.jpg");
var body = await axios({ method: 'POST', url : "myUrl", data : file });
But none of them worked as i wanted.
Actual working example from JQuery AJAX in Browser
var fileupload = $("#inpFile")[0];
var file = fileupload.files[0];
$.ajax({
url: "https://hookb.in/b9gqlwbZeaT3DDogQ7Om",
type: 'POST',
success: function (response) {
DisplayMessage(response);
},
data: file,
contentType: false,
processData: false
});

Have you tried setting the content-type header?
Per Talg123 I found that if you set contentType to false in jQuery it might be equivalent to multipart/form-data.
client side:
async function main(){
try{
const buffer = new ArrayBuffer(8);
const data = new FormData();
const blob = new Blob([buffer],{type : 'multipart/form-data'});
data.append('data', blob);
const options = {
url: "https://hookb.in/b9gqlwbZeaT3DDogQ7Om",
method: 'POST',
headers: { 'content-type': 'multipart/form-data' },
data
};
let result = await axios(options);
console.log(result);
}catch(e){
console.error("error",e);
}
}
main()
<script src="https://cdnjs.cloudflare.com/ajax/libs/axios/0.19.2/axios.min.js"></script>
server side per https://github.com/axios/axios/issues/1006#issuecomment-584840380
const axios = require('axios');
const FormData = require('form-data');
// Where buffer is a file
formData.append('file', buffer);
// Added a promise version like seen in earlier comments to get this
const contentLength = await formData.getLength();
await axios(`<ENDPOINT>`, {
method: 'POST',
baseURL: <BASE_URL>,
params: {
fileName: '<FILE_NAME>.png'
},
headers: {
authorization: `Bearer <TOKEN>`,
...formData.getHeaders(),
'content-length': contentLength
},
data: formData
});
