/aws-s3-upload-pre-signed-demo

example of using lambda for generating pre-signed urls to upload files to s3

Primary LanguageGo

aws-s3-upload-pre-signed-demo

This a demo project for uploading files to an s3 bucket using a pre-signed url issued by a lambda function.

The frontend is a static HTML + javascript page deployed also on the same bucket

install

Just clone the repo and make sure you have serverless framework installed

For deploying the lambda function first run make to compile the golang lambda:

make

and then:

sls deploy

This will deploy the lambda and generate an endpoint like: https://xxxxxx.execute-api.us-east-2.amazonaws.com/dev/purl

When called the lambda return a json with a random file name and a pre-signed-url

curl https://xxxxxxxxxxxx.execute-api.us-east-2.amazonaws.com/dev/purl
{  
   "file":"tmp-52fdfc072182654f163f5f0f9a621d72",
   "url":"https://aws-upload-pre-signed-bucket.s3.us-east-2.amazonaws.com/tmp-52fd........"
}

Now to deploy the frontend, just copy the endpoint url and add it to the client/dist/index.html

and now deploy:

sls client deploy
