Implementing Nix Flakes requires the creation of a default entrypoint for scripts to ensure that that application module can be effectively combined within the project structure. This default.nix file includes a shell definition with necessary build inputs such as awscli, curl, docker, git, gnumake, openssh, and rsync. By adding this default entrypoint, developers can utilize Nix Flakes to streamline the combination of application modules within the project.
The commit introduces a `flake.lock` and `flake.nix` file, defining the project's dependencies and configuration. The `flake.nix` file sets up a Nix Flake for the GovTool and utilities monorepo, specifying inputs from nixpkgs and generating packages for supported systems such as x86_64-linux, aarch64-linux, x86_64-darwin, and aarch64-darwin. Additionally, the `scripts` attribute is included to allow for a scripts environment from `scripts/govtool`, ensuring a versatile Nix-shell setup for all supported systems.
The user story requires utilizing Nix Flakes to combine application modules within a project to enhance manageability and organization. In this commit, the .envrc example was relocated from `scripts/govtool/.env.example` to the root directory as `.env.example`. By moving this file, we align with the objective of making the application modules accessible from the root of the project. The modification ensures that the necessary environment configuration template is centrally located, facilitating the use of Nix Flakes for streamlined module combination. Changes: - The `.envrc` example file has been moved from `scripts/govtool/.env.example` to the project's root directory as `.env.example`. - The file contents were adjusted to remove references to the previous directory structure and updated to indicate the use of Nix Flakes configuration. - The relocation enhances accessibility and clarity, aligning with the goal of effectively combining application modules using Nix Flakes for improved project structure and management.
The user story necessitates utilizing Nix Flakes to combine application modules within the project for better organization and manageability. This commit integrates the backend environment into the Nix Flakes as one of the outputs, aligning with the objective of enhancing accessibility and usability of application modules from the project's root. By adding the backend as an output, developers can effectively combine and utilize the backend environment using Nix Flakes for improved project structure and management. Changes: - Added the backend environment as an output in the `flake.nix` file. - Modified `govtool/backend/default.nix` to include the recommended Haskell compiler version and additional tools needed for the backend. - Updated the entrypoint to provide necessary build inputs and display a welcome message for the backend development shell. - Removed unnecessary files `shell.nix` and `sources.nix` related to the backend environment setup.
Integrating the infrastructure environment into the Nix Flakes configuration is crucial for combining application modules effectively within the project structure. By updating the `flake.nix` file, the infrastructure environment is now part of the Nix Flakes configuration, enabling streamlined access and utilization of infrastructure-related tools. The changes include incorporating the infrastructure package in the `flake.nix` file, moving `default.nix` to infra/terraform directory, and removing unnecessary files related to the shell environment setup. This enhancement aligns with the user story's goal of utilizing Nix Flakes to combine application modules for improved project organization and accessibility. Changes: - Added the infrastructure package to the `flake.nix` configuration for Nix Flakes. - Moved `default.nix` to the `infra/terraform` directory to establish the infrastructure environment setup within the project. - Removed unnecessary files related to the shell environment setup in the `infra/terraform` directory to streamline the project structure.
The purpose of this commit is to create .envrc files within specific modules that reference the root .envrc file and utilize the corresponding flake for configuration. By establishing these .envrc files in the `backend`, `infra`, and `scripts` modules, the project enhances the organization and management of application modules using Nix Flakes. This setup ensures that each module aligns with the root configuration, streamlining the usage of Nix Flakes for combining application modules effectively within the project structure. Changes: - Renamed .env.example to .envrc.example, ensuring consistency in naming conventions. - Added a new .envrc file in the `govtool/backend` directory, referencing the root environment and using the corresponding flake for the backend module. - Created a .envrc file in the `infra/terraform` directory, linking to the root environment and utilizing the appropriate flake for the infrastructure module. - Introduced a .envrc file in the `scripts/govtool` directory, pointing to the root environment and leveraging the matching flake for the scripts module setup.
…f the project The relocation of the DOMAIN definition from the subdirectory specific .envrc files to the master .envrc file in the root directory streamlines the access to and management of environment variables within the project. As per the user story requirements to enhance organization and accessibility of application modules using Nix Flakes, this adjustment ensures that the domain configuration is centralized, simplifying the integration of the application modules. By consolidating this setting in the main .envrc file, developers can effectively coordinate and utilize the domain configuration across different project components, aligning with the goal of leveraging Nix Flakes for improved project structure and ease of use. Changes: - Moved the DOMAIN definition logic from individual .envrc files to the main .envrc file in the project's root directory. - Updated the .envrc.example file to reflect the changes in domain configuration logic for different environments. - Streamlined domain configuration setups for various environments (dev, test, staging, beta) within the central .envrc file, enhancing clarity and accessibility for developers working on the project.
Integrating a frontend module into the Nix Flakes configuration is essential for combining application modules within the project effectively. The frontend module's addition is in alignment with the user story's goal of utilizing Nix Flakes to enhance project manageability and organization. By including the frontend module, developers can streamline the usage and integration of frontend-related tools and configurations, fostering a cohesive structure for the application. This commit expands the project's capabilities by incorporating a frontend module into the Nix Flakes setup. Changes: - Integrated the `node_nixpkgs` input to the `flake.nix` file, allowing for frontend-specific dependencies in the Nix Flakes configuration. - Created a `.envrc` file within the `govtool/frontend` directory, defining environment variables for the frontend module and setting up the necessary configurations. - Updated the Dockerfile in the `govtool/frontend` directory to include variables related to the Vite base URL and other frontend settings. - Adjusted the `default.nix` file in the `govtool/frontend` directory to enhance the frontend project configuration and provide a tailored development shell setup. The update includes a welcome message and necessary cleanup processes for improved project development experiences.
Provide comprehensive documentation on utilizing Nix with the project to enhance development processes and streamline environment setup. The .envrc files are updated to ensure compatibility with Nix configurations, facilitating package installation and project building. This documentation emphasizes the use of Nix and Direnv for effective project setup and module combination within the GovTool project structure. Changes: - Updated `README.md` in `govtool/backend` to include instructions for utilizing Nix and Direnv, aligning the setup with Nix Flakes configuration. - Revised `README.md` in `govtool/frontend` to streamline instructions for using Nix and Direnv, ensuring proper environment setup and dependencies for the frontend module development.
