epubify is a Python program that creates an ePUB ebook from a list of URLs. lambda-epubify is a project to run epubify on AWS Lambda.

To run this project on Lambda, you'll need to build it first on Amazon Linux. In the future, a release will be provided with a pre-built ZIP file ready to upload to Lambda.

1. Provision an EC2 instance running Amazon Linux. The instance needs at least 1GB of RAM in order to compile lxml, so a t2.nano instance cannot be used to build this project.
2. Install git: sudo yum update && sudo yum install -y git
3. Clone this repository: git clone https://github.com/scascketta/lambda-epubify.git
4. Install lxml's dependencies by running the bootstrap.sh script.
5. Run the build.sh script to build a ZIP file.

The ZIP file created on step 4 is ready to be uploaded to AWS Lambda and invoked. The handler filename is handler, the handler func is called handler.

lambda-epubify essentially takes a list of URLs, turns them into an ebook, and then saves that ebook into an S3 bucket.

Specifically, it expects a payload that looks like this:

{
  "output": {
    "key": "<s3-key>", // the full S3 key for the created ePUB file (e.g. 'epubify-test.epub')
    "bucket": "<your-s3-bucket>" // the S3 bucket to place the ePub file in
  },
  "title": "<your-title>",
  "urls": [
    "<url-1>"
    ...
    "<url-N>"
  ]
}
