Usage

wkhtmltopdf binary will be extracted to the /opt/bin.

wkhtmltopdf can be executed directly as a command line binary, or via a wrapper.

Refer to /tests directory for example usage.

Build, Test, Publish

Refer to the following scripts to build and publish your own wkhtmltopdf layer.

1. Run ./build.sh to build a new layer zip.
2. Run ./test.sh to test the layer zip.
3. Run ./publish.sh to publish the layer zip to regions specified in /config/regions.txt.

Fonts

See fonts-aws-lambda-layer to use fonts on AWS Lambda.

libjpeg.so.62: cannot open shared object file

This is fantastic. Thank you!

I'm running into one issue while replicating what's going on in the tests locally:

index.js

let { execSync } = require('child_process');

exports.handler = async (event, context, callback) => {
  execSync("ldd /opt/bin/wkhtmltopdf", { encoding: "utf8", stdio: "inherit" });
  execSync("wkhtmltopdf -V", { encoding: "utf8", stdio: "inherit" });

  callback(null, {'foo': 'bar'});
};

It appears to be finding most of the libraries, but a few are missing. Do you know what might be the issue?

Problem with fonts

I was trying nodejs12.x runtime, I didn't succeed.

wkhtmltopdf does not emit any error the pdf is generated.

But you don't see characters just squares.
I was investigating and it seems that the fonts are missing.

You can try the function here

echo "<html><body>Test</body></html>" | http --download POST https://kt7b9gdixh.execute-api.us-east-1.amazonaws.com/dev/converter

GLIBC_2.25 not found

Installed the eu-west-2 layer for a Larvel Vapor project for use with snappy, but getting this error:
message: "The exit status code '1' says something went wrong:↵stderr: "/opt/bin/wkhtmltopdf: /lib64/libc.so.6: version `GLIBC_2.25' not found (required by /opt/lib/libuuid.so.1)↵"↵stdout: ""↵command: /opt/bin/wkhtmltopdf --lowquality --encoding 'utf-8' --footer-font-size '8' --footer-left 'Please acknowledge receipt of this claim immediately.

I assume it's because Amazon Linux 2 doesn't include all the necessary packages by default, but the main page states these layers are compatible with AL2?
