Convert DOCX to PDF Programmatically: AWS Lambda & LibreOffice

Awais Ahmad — Wed, 12 Feb 2025 03:14:00 +0000

Introduction

Converting documents from DOCX to PDF while maintaining formatting can be a challenging task. Many libraries exist for document conversion, but they often fall short in preserving the exact layout, fonts, and styles. This was a major issue for me until I discovered an efficient cloud-based solution using AWS Lambda and LibreOffice in headless mode.

In this article, I’ll share my experience setting up document conversion in the cloud using AWS Lambda, Docker, and LibreOffice, providing a seamless and reliable way to process files without worrying about server management.

The Challenge: Keeping Formatting Intact

When working with document conversions, formatting is crucial. Many tools can handle the basic DOCX to PDF conversion, but the output often looks different from the original document. I needed a solution that:

Preserves fonts, styles, and layouts
Works in a serverless environment
Is easy to scale and manage

That’s when I came across @shelf/aws-lambda-libreoffice, a powerful package that runs LibreOffice in a headless mode within AWS Lambda, making it perfect for cloud-based document processing.

Solution: AWS Lambda with LibreOffice

Why Use AWS Lambda?

AWS Lambda is a serverless computing service, meaning you don’t need to worry about managing infrastructure. It automatically scales and only runs when needed, making it cost-effective and efficient. By using Lambda, you can process document conversions on demand without maintaining a dedicated server.

Why LibreOffice in Headless Mode?

LibreOffice is one of the most reliable document processing tools. When run in headless mode, it can process documents programmatically without requiring a GUI, making it an excellent choice for automated conversions.

Dockerizing LibreOffice for AWS Lambda

Since AWS Lambda has certain limitations on package size and dependencies, we need to containerize our solution using Docker. Thankfully, the @shelf/aws-lambda-libreoffice package provides a pre-configured Docker image, which simplifies deployment.

Steps to Set Up DOCX to PDF Conversion in AWS Lambda

1. Use a Pre-built Docker Image

To save time, I used a public Docker image that includes everything needed for LibreOffice in AWS Lambda. Here’s the base image:

FROM public.ecr.aws/shelf/lambda-libreoffice-base:7.6-node18-x86_64

2. Set Up the AWS Lambda Function

We need to create an AWS Lambda function that:

Accepts a DOCX file as input
Converts it to PDF using LibreOffice in headless mode
Returns the converted PDF

Here’s a simple Node.js script to handle the conversion:

const { execSync } = require("child_process");
const fs = require("fs");
const path = require("path");

exports.handler = async (event) => {
    const inputFilePath = "/tmp/input.docx";
    const outputFilePath = "/tmp/output.pdf";

    fs.writeFileSync(inputFilePath, Buffer.from(event.body, "base64"));

    execSync(`libreoffice --headless --convert-to pdf --outdir /tmp ${inputFilePath}`);

    const pdfBuffer = fs.readFileSync(outputFilePath);

    return {
        statusCode: 200,
        headers: { "Content-Type": "application/pdf" },
        body: pdfBuffer.toString("base64"),
        isBase64Encoded: true,
    };
};

3. Build and Push the Docker Image to AWS ECR

After setting up the Dockerfile, build and push the image to AWS Elastic Container Registry (ECR):

docker build -t libreoffice-converter .
docker tag libreoffice-converter:latest <your-aws-account-id>.dkr.ecr.<region>.amazonaws.com/libreoffice-converter
aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <your-aws-account-id>.dkr.ecr.<region>.amazonaws.com
docker push <your-aws-account-id>.dkr.ecr.<region>.amazonaws.com/libreoffice-converter

4. Deploy the AWS Lambda Function

Now, create an AWS Lambda function and use the container image you just pushed to AWS ECR. Ensure that the function has sufficient memory (512MB or more) to handle conversions efficiently.

5. Test the Conversion

To test the function, upload a sample DOCX file and trigger the Lambda function. It should return a well-formatted PDF, preserving all styles and layouts.

Benefits of This Approach

✅ No server management – AWS Lambda handles execution automatically.
✅ Accurate formatting – LibreOffice ensures high-quality conversions.
✅ Scalability – The function can handle multiple conversions without additional infrastructure.
✅ Cost-effective – You only pay for the compute time when the function runs.

Conclusion

If you’re struggling with DOCX to PDF conversion while maintaining formatting, AWS Lambda with LibreOffice in headless mode is an excellent solution. By leveraging serverless computing and containerization, you can achieve high-quality document processing without the hassle of managing servers.

Gitflow: A Comprehensive Guide for Developers

Awais Ahmad — Mon, 10 Feb 2025 03:26:35 +0000

Gitflow is a strategy for managing your code efficiently. It is an essential tool for version control in software development, enabling teams to collaborate seamlessly. Originally proposed by Vincent Driessen, Gitflow introduces a structured workflow that helps developers manage feature development and bug fixes systematically.

In this guide, we will explore Gitflow, how it works, how to implement it in your project, and whether Gitflow is suitable for you.

Why Use Gitflow?

Imagine you're working on a large-scale project with multiple developers working simultaneously. How would you ensure the code is bug-free and production-ready? For stable code, we need some checks in place. That's where Gitflow comes into play.

Key Benefits of Gitflow

Provides a clear structure for collaboration.
Ensures a stable, production-ready main branch.
Separates ongoing development from production releases.
Facilitates parallel development of features.
Simplifies bug fixes and hotfixes.

Gitflow Branches

Gitflow starts with two primary branches:

1. Main Branch (`main`)

Holds the production-ready code.
Always deployable and should remain stable.

2. Development Branch (`develop`)

This is where active development takes place.
Serves as the integration branch for new features before they are merged into main.

In addition to these, Gitflow includes supporting branches for better organization:

**3. Feature Branches (`feature/*`)**

Used for developing new features.
Created from the develop branch.
Merged back into develop once the feature is complete.

**4. Release Branches (`release/*`)**

Used to prepare for a new release.
Created from the develop branch.
Stabilized before being merged into both main and develop.

**5. Hotfix Branches (`hotfix/*`)**

Used for urgent bug fixes in production.
Created from the main branch.
Merged back into both main and develop to keep all branches updated.

Would you like me to add or refine anything further? 🚀

Gitflow in Action

Consider that you already have a main branch and want to implement Gitflow manually using basic Git commands.

Step 1: Create a `develop` Branch

The develop branch serves as the main integration branch where new features are merged.

git checkout -b develop main

Step 2: Create a Feature Branch

New features should be developed in isolated branches to prevent conflicts. Create a new branch from the develop branch:

git checkout -b feature/<feature-name> develop

After working on the feature, commit your changes and merge them back into develop:

git checkout develop
git merge feature/<feature_name>
git branch -d feature/<feature-name>

Step 3: Create a Release Branch

Once the develop branch is stable and ready for release, create a release branch.

git checkout -b release/<version> develop

After performing final tests and fixes, merge the release branch into both main and develop:

git checkout main
git merge release/<version>
git checkout develop
git merge release/<version>
git branch -d release/<version>

Step 4: Create a Hotfix Branch

If a critical bug is found in production, create a hotfix branch from main:

git checkout -b hotfix/<name> main

Once the bug is fixed, merge it back into both main and develop:

git checkout main
git merge hotfix/<name>
git checkout develop
git merge hotfix/<name>
git branch -d hotfix/<name>

Best Practices for Gitflow

Always create pull requests (PRs) instead of merging manually.
Resolve merge conflicts carefully before merging branches.
Keep feature branches short-lived to prevent conflicts.
Test thoroughly before merging into main.
Maintain clear commit messages to track changes effectively.

Conclusion

Gitflow is a powerful workflow for teams working on large projects. It provides a clear and structured approach to managing code versions, ensuring production stability while enabling parallel development. However, for smaller teams or projects with frequent deployments, a simpler workflow like GitHub Flow might be more suitable.

By following best practices, you can leverage Gitflow effectively to enhance collaboration, streamline development, and maintain a stable codebase.
