elmpackagejson

elmpackagejson is a file used by the Elm programming language to manage project dependencies and metadata. It follows a standardized JSON format. The file typically resides in the root directory of an Elm project. It contains essential information such as the project's name, version, and author. Crucially, it lists the project's direct dependencies, specifying the package name and the exact version range required. This allows the Elm package manager to resolve compatible versions of all necessary libraries.

Beyond dependencies, elmpackagejson can include fields like `elm-version` to indicate the compatible Elm compiler version for the project. It also defines an `exposed-modules` list, which dictates which modules from the project are made available to other projects that depend on it. This file plays a vital role in ensuring reproducible builds and facilitating the sharing of Elm code within the community. When you add or remove dependencies using the Elm package manager, these changes are reflected in the elmpackagejson file. It acts as the central manifest for any Elm project.
