# Zeplin HTML to PDF Lambda

This is an AWS Lambda function that converts HTML pages to PDF documents using wkhtmltopdf (0.12.4). It implements a simple interface to read HTML input and output PDF content.

> **WARNING**: You must use v2.x.x tag if you are using Node.js runtime >=10.x in AWS Lambda.

## Input

Input event to this function has the following structure: 

```

{

    "html": "HTML docContent"

}

```

## Output

It yields a response in the following format: 

```

{

  "data": "JVBERi0xLjQKMSAwIG9iago8PAovVGl0bGUgKP7..."

}

```

`data` is base64 encoding of the converted PDF file. 

## Test in local environment

The function can be tested locally using [AWS SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-command-reference.html). You can change contents of `events/example-event.json` or you can create a new file which you will give sam as an event parameter.

```

sam local invoke "HtmlToPdf" -e events/example-event.json

## Deploying to AWS

There are two ways in which these functions can be deployed to AWS.

1 - Check our `npm run deploy:dev` and `npm run deploy:prod` commands in `package.json` and change it according to your needs. Do not forget to add environment variables (you can find it under `template.yml`) to your lambda function in aws lambda edit page or running [lamba update-function-configuration command](https://docs.aws.amazon.com/cli/latest/reference/lambda/update-function-configuration.html). Be sure to create the following environment variable in Lambda: `FONTCONFIG_PATH=/var/task/fonts`

2 - Check out `template.yml` file and edit according to your needs then use `sam deploy`.
