Proposed Solution

To address the problem, a new build script has been developed with the following key features:

  • Clones the new monorepo: The script begins by cloning the new monorepo using a shallow clone, which reduces the download size and speeds up the build process. Shallow cloning retrieves only the most recent commit history, significantly decreasing the time and resources required for the initial setup.
  • Uses pnpm: The script leverages pnpm, a fast and efficient package manager, as defined in the project. Pnpm's use of a content-addressable file system ensures that dependencies are installed only once, regardless of how many projects use them, thereby saving disk space and improving installation speed.
  • Runs pnpm run dist: The script executes the pnpm run dist command to build the UMD (Universal Module Definition) bundle from the packages/core directory. This step is crucial for generating the distributable version of the core library that can be used in various environments.
  • Extracts version and library name: The script automatically extracts the version and library name from the built artifacts. This automation eliminates the need for manual updates and ensures that the version information is always accurate.
  • Injects into addon/lib/flow-scanner-core.js: Finally, the script injects the extracted version and library name into the addon/lib/flow-scanner-core.js file. This step integrates the built core library into the Inspector Reloaded addon, making it available for use within the application. By automating these steps, the new build script ensures a reliable and efficient process for updating the Flow Scanner core library in Inspector Reloaded.

Detailed Steps for Implementing the Solution

Implementing the proposed solution involves several steps to ensure that the Inspector Reloaded build script is correctly updated to use the new monorepo. Each step is crucial for a successful transition and to maintain the functionality of the application.

1. Clone the New Monorepo

The first step is to clone the new monorepo, which hosts the Lightning Flow Scanner core library. To expedite the process and reduce the download size, a shallow clone is used. This method retrieves only the most recent commit history, which is sufficient for building the library. The command to perform a shallow clone is as follows:

git clone --depth 1 https://github.com/Flow-Scanner/lightning-flow-scanner.git

This command clones the repository into a local directory, allowing you to access the necessary files for the build process. Cloning the repository is a fundamental step in updating the build script, as it provides the source code required for building the UMD bundle. Ensuring that the clone is successful is crucial before proceeding to the next steps. A shallow clone is particularly beneficial for CI/CD pipelines, where build times are critical. By reducing the amount of data that needs to be downloaded, the build process becomes more efficient and less resource-intensive. This step sets the foundation for the rest of the build process, ensuring that all subsequent operations have access to the latest version of the core library.

2. Install Dependencies with pnpm

Once the monorepo is cloned, the next step is to install the necessary dependencies using pnpm. Pnpm is a package manager that is designed to be fast and efficient, making it an ideal choice for managing project dependencies. The command to install the dependencies is:

pnpm install

This command reads the pnpm-lock.yaml file in the monorepo and installs all the required packages. Pnpm's unique approach to dependency management ensures that packages are only installed once, regardless of how many projects depend on them, saving disk space and improving installation speed. Installing dependencies is a critical step in the build process, as it ensures that all the necessary libraries and tools are available for building the UMD bundle. Without the correct dependencies, the build process will likely fail. Pnpm's efficiency in handling dependencies makes it a valuable tool for large projects like Inspector Reloaded, where numerous dependencies are involved. This step ensures that the build environment is properly set up, paving the way for the subsequent build steps. By using pnpm, the project benefits from its speed and consistency, ensuring that the build process is reliable and repeatable.

3. Build the UMD Bundle

After installing the dependencies, the next step is to build the UMD bundle from the packages/core directory. The UMD bundle is a JavaScript file that can be used in a variety of environments, including browsers and Node.js. To build the UMD bundle, run the following command:

pnpm run dist

This command executes the dist script defined in the package.json file of the packages/core directory. The script typically uses a build tool like Rollup or Webpack to bundle the source code into a single UMD file. Building the UMD bundle is a crucial step, as it creates the distributable version of the core library. This bundle contains all the necessary code and assets required for the library to function correctly in different environments. The pnpm run dist command ensures that the build process is consistent and follows the defined build configuration. This step is essential for generating the final artifact that will be integrated into Inspector Reloaded. The UMD format is particularly useful because it provides compatibility across various module systems, making the library easily integrable into different projects. By building the UMD bundle, the library is prepared for deployment and usage in a wide range of applications.

4. Extract Version and Library Name

Once the UMD bundle is built, the next step is to extract the version and library name from the generated files. This information is necessary for properly integrating the library into Inspector Reloaded. The build script should automatically extract this information to avoid manual updates and ensure accuracy. The version and library name are typically stored in the package.json file of the packages/core directory or within the built UMD bundle itself. The script can use tools like jq or regular expressions to parse the package.json file and extract the required information. Additionally, the UMD bundle may contain comments or metadata that include the version and library name. Automating this extraction process is crucial for maintaining the build script's efficiency and reducing the risk of errors. Manual extraction can be time-consuming and prone to mistakes, especially when dealing with frequent updates. By automating this step, the build process becomes more reliable and less dependent on human intervention. This ensures that the correct version and library name are always used, contributing to the overall stability and maintainability of Inspector Reloaded.

5. Inject into addon/lib/flow-scanner-core.js

The final step is to inject the extracted version and library name into the addon/lib/flow-scanner-core.js file. This file is part of the Inspector Reloaded addon and is responsible for loading and using the Lightning Flow Scanner core library. The build script should modify this file to include the correct version and library name, ensuring that Inspector Reloaded uses the latest version of the core library. The injection process typically involves reading the contents of addon/lib/flow-scanner-core.js, inserting the version and library name at the appropriate locations, and then writing the modified content back to the file. This step is crucial for integrating the built core library into Inspector Reloaded. Without this injection, Inspector Reloaded would not be able to use the updated core library, defeating the purpose of the build script update. Ensuring that the version and library name are correctly injected is essential for the proper functioning of Inspector Reloaded. This final step completes the build process, making the updated Lightning Flow Scanner core library available for use within the application. By automating this injection, the build script ensures a seamless and efficient update process.

Benefits of the Solution

Implementing the updated build script offers several significant benefits, enhancing the project's overall efficiency and maintainability. These benefits include:
