# Consistent Filename Casing (TS)

Date: 2025-05-14

Status: accepted

## Context

TypeScript follows the case sensitivity rules of the file system it’s running
on. This can be problematic if some developers are working in a case-sensitive
file system and others aren’t. If a file attempts to import fileManager.ts by
specifying ./FileManager.ts the file will be found in a case-insensitive file
system, but not on a case-sensitive file system.

When this option is set, TypeScript will issue an error if a program tries to
include a file by a casing different from the casing on disk.

## Decision

Set
[`forceConsistentCasingInFileNames`](https://www.typescriptlang.org/tsconfig/forceConsistentCasingInFileNames.html)
to true in Typescript

## Consequences

Ensure seamless workflow between developers with different operating systems.
