Introduction

In the realm of dynamic web applications, user-generated content is a double-edged sword: it drives engagement but demands robust moderation. Efficiently reviewing and managing content is critical for maintaining platform quality and user safety. The challenge lies in building a system that is both secure and scalable, allowing administrators to moderate content without friction.

In the Justifai project, maintaining up-to-date and accurate architecture documentation for our evolving serverless environment was a consistent challenge. As features rapidly develop and AWS services are integrated, manual diagrams quickly become stale, leading to misunderstandings and increased onboarding time.

Ever been blocked at the final hurdle of deployment by something as seemingly simple as a file upload? For the justifai project, preparing for an end-to-end demo revealed a common, yet critical, oversight: S3 Cross-Origin Resource Sharing (CORS) configurations. This often overlooked detail can halt browser-based uploads dead in their tracks, especially when using presigned URLs, leading to

Developing a frontend application, specifically for the justifai project, presented an unexpected hurdle: a blank white page immediately after loading. The root cause? A ReferenceError: global is not defined error, stemming from the amazon-cognito-identity-js module.

The Problem

The amazon-cognito-identity-js library, often used with AWS Amplify for authentication, was originally

Introduction

In the realm of Single Page Applications (SPAs), a compelling user interface can be a powerful differentiator. For the "justifai" project, we've taken this to heart, embarking on a significant visual transformation to introduce a unique 'dossier administratif' (administrative folder) aesthetic.

In the justifai project, our document processing pipeline relies heavily on AWS Textract for extracting information from various file types. However, a critical issue emerged: when Textract encountered an unsupported document format, such as a PDF that Textract's synchronous API couldn't process, our AWS Lambda function would fail.

In the justifai project, a critical aspect of the dashboard functionality involves managing document statuses, specifically through validation and rejection. These operations require sending PATCH requests to the backend API to update document records. However, users were encountering issues where these updates were unexpectedly failing.

The Challenge: CORS and PATCH Requests

In the ongoing development of the viaops project, recent updates have focused on refining both the end-user experience and developer workflows. These improvements range from subtle UI tweaks to significant CI/CD optimizations, all aimed at making the platform more intuitive and efficient.

Elevating User Interface and Interaction

The user interface received several thoughtful updates.

The justifai project involves critical document processing, where administrators rely on a dashboard to efficiently review and validate documents. Previously, the user experience for making these decisions had a small but significant flaw: validated document cards would disappear almost immediately after an action, making the visual confirmation of a decision fleeting and difficult to audit.

For the justifai project, clarity in our increasingly complex serverless architecture is paramount. As microservices proliferate and responsibilities become more distributed, keeping a holistic view of the system's structure and data flows is a significant challenge.

The Challenge of Distributed Systems Documentation

Serverless applications, while offering immense flexibility and
