Yesterday I did a deep night coding session and created a small node.js/JS (well actually CoffeeScript, but CoffeeScript is just JavaScript so lets say JS) app.
what's the goal:
step 1 is done.
the server now has a string a la
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAMgAAADICAYAAACt...
my question is: what are my next steps to "stream"/upload this data to Amazon S3 and create an actual image there?
knox https://github.com/LearnBoost/knox seems like an awesome lib to PUT something to S3, but what I'm missing is the glue between the base64-encoded-image-string and actual upload action?
Any ideas, pointers and feedback welcome.
For people who are still struggling with this issue. Here is the approach I used with native aws-sdk:
var AWS = require('aws-sdk');
AWS.config.loadFromPath('./s3_config.json');
var s3Bucket = new AWS.S3( { params: {Bucket: 'myBucket'} } );
Inside your router method (ContentType should be set to the content type of the image file):
buf = Buffer.from(req.body.imageBinary.replace(/^data:image\/\w+;base64,/, ""),'base64')
var data = {
Key: req.body.userId,
Body: buf,
ContentEncoding: 'base64',
ContentType: 'image/jpeg'
};
s3Bucket.putObject(data, function(err, data){
if (err) {
console.log(err);
console.log('Error uploading data: ', data);
} else {
console.log('successfully uploaded the image!');
}
});
s3_config.json file:
{
"accessKeyId":"xxxxxxxxxxxxxxxx",
"secretAccessKey":"xxxxxxxxxxxxxx",
"region":"us-east-1"
}
