The Fix Require Modules plugin for Obsidian enhances the experience of working with JavaScript and TypeScript by fixing limitations related to module imports within Obsidian. It allows users to seamlessly work with custom JavaScript/TypeScript scripts, including those used in Dataview, Templater, and other plugins. The plugin introduces advanced functions like `require()` and `requireAsync()` for both desktop and mobile, making it possible to import modules and work with files from relative paths, system paths, and even URLs. Additionally, the plugin offers improved support for ECMAScript and TypeScript modules, making it easier to integrate and develop scripts in a modern development environment.

The Modules plugin enhances Obsidian by allowing users to load and use JavaScript and TypeScript modules from both the vault and external sources. It enables the use of popular plugins like Dataview and Templater, while supporting different module formats such as CommonJS and ES modules. The plugin offers easy integration of modules, supports circular dependencies, and resolves file paths including relative, vault, markdown links, and external URLs. It also adds debugging support with source maps and allows users to create and import custom modules within their vault, providing a powerful, flexible system for script-based workflows.
