mockoon-config-transformer

A CLI tool to bundle/extract Mockoon environment files in a git-friendly files tree with 100% backward compatibility.

Features

• Extracts the original big Mockoon environment file into a user-friendly (git-friendly) file tree.
• Generates markdown documentation files based on the documentation fields within the Mockoon environment file.
• Bundle the extracted file tree into an environment file that matches the original file.

See examples:

• Original Mockoon stripe config environment.json
• Extracted Mockoon stripe config json tree
• Extracted automatically generated documentation.md
• Bundled json tree from-json.json

Extract features

• Successfully processed any URI with special characters.
• Handled duplicated routes, responses, and data cases within the Mockoon configuration.
• Ensured compatibility with updates to the Mockoon configuration structure, processing unexpected properties when encountered.
• Handled edge cases related to file issues on the operating system, including file and directory name length.
• Extracted the directory tree related to route-endpoint paths.
• Extracted the response body into a multiline file.
• Extracted the data bucket values into a multiline file.

Bundle features

• The bundled environment is not based on escaped directory names.
• Correctly restores array ordering (routes, responses, etc)
• Correctly restores unknown properties

Motivation

Mockoon currently stores each environment in a single JSON file. This file has a complex and extensive structure, making it challenging to resolve version control conflicts when multiple developers are working in the same environment simultaneously.

Developers urgently need a solution to store environment files in version control systems and facilitate clean review processes for environment updates.

At some point, Mockoon will adopt a more Git-friendly environment file structure. Therefore, our main principle is as follows:

This tool interacts with the Mockoon environment file without adding any additional values, ensuring a full restoration of the original Mockoon configuration. This allows you to discontinue using this tool at any time."

How is the CLI tool tested?

Mockoon has 2000+ samples of the APIs, which is hosted in the mock-samples repo.

Each release of that CLI tool includes a test of these APIs that described in the samples could be extracted and then correctly bundled. That means any feature that is used in the mock-samples of the Mockoon is correctly processed by the CLI tool.

For the edge cases (e.g. dirs that are not used in the mock-samples, or dirs with the same names) we have the examples dir, where described a few examples and specific edge cases and these examples also used in the tests.

So the release means all Mockoon mock-samples are correctly extracted and then bundled and the bundles are equal to the original environment files, and some edge cases are also tested.

Usage

Extract

Extracts the original Mockoon environment file into user-friendly file tree.

# Extract environment.json into output-dir

yarn mockoon-config-transformer extract -i ./environment.json -o ./output-dir

# Extract remote environment file by URI  into output-dir

yarn mockoon-config-transformer extract \ 
  -i https://raw.githubusercontent.com/mockoon/mock-samples/main/mock-apis/data/1forgecom.json \ 
  -o ./output-dir

Bundle

Bundle extracted directory to the environment file that equals the original file.

yarn mockoon-config-transformer bundle -i ./output-dir/index.json -o ./environment.json

Extracted files tree structure details

To make the extracted structure safe for duplicates special chars, future Mockoon releases, etc. the "bundle" functionality is based not on the directories tree, but on the file's content.

The files tree has just a view-friendly structure not really related to the file that will be bundled from that tree structure.

The directories tree equals the routes path names, but the directory names skipped some special chars to make directory names and tree structure safe for the OS.

Each directory could have index.json file, includes.json.
Each directory could have optional documentation.md file.

• documentation.md this file includes generated documentation text from the environment file based on the documentation fields of the Mockoon environment file.

• index.json file the main file that includes all properties except properties that moved to includes file.

• includes.json file with ordered list of the nested data. The content of that file related to the index.json data type.

When the index.json data is object then includes is key:value extend object, where is the key is extra property of the index object and the value is a file path where the value stored is.

When the index.json data is an array, then includes is a ordered file paths of where the array items stored is.
