L7 Informatics specializes in redefining data intelligence for life sciences and healthcare organizations. Their flagship product, L7|ESP, is an FDA regulatory compliant platform equipped with a suite of pre-built apps and connectors, designed to streamline workflows and foster digital transformation.


As the collaboration between Code Poets and L7 Informatics evolved, the natural diversity in coding styles among the expanding team became evident. Each developer's unique approach, while a reflection of their individual expertise, started to introduce variations in the front-end code's consistency. During this phase of ongoing development and bug fixing, Code Poets identified an opportunity for further refinement. This led to the strategic decision to integrate ESLint, aiming to harmonize these diverse coding styles while respecting the individuality of each team member.


The main challenge was the varying personal coding styles among the growing number of developers, which led to inconsistent code in numerous components. This inconsistency was not just a matter of aesthetics but also affected the efficiency and clarity of the codebase.

1. ESLint Integration
Code Poets created a separate branch for integrating ESLint with a recommended set of rules tailored for JavaScript and HTML code. This process identified thousands of warnings and errors in the existing codebase.

2. Automated and Manual Code Fixes
The team utilized ESLint’s capabilities for automatic fixes and performed manual tests and corrections to ensure the application’s functionality remained intact.

3. Rule-by-Rule Code Correction
Each rule violation was addressed individually, facilitating a detailed review and decision-making process for the application of each principle. This approach also led to the creation of a document for collaborative analysis and input from the development team.

4. Pre-commit Hook Implementation
To maintain code quality, a pre-commit hook was added to ensure all new code submissions complied with the established ESLint rules.

Highlighted results

Over 20,000 lines of code were modified for better consistency

A unified, regimented frontend code style was achieved
