Searching for a REST Client with Local Collection Storage for Microservice Ecosystems

In the realm of modern software development, particularly within microservice architectures, efficient management of API testing environments is crucial. Developers often utilize REST clients to streamline their testing processes, but challenges can arise when attempting to organize and synchronize those test collections across multiple repositories.

The Need for Local, Folder-Based Storage in REST Clients

Typically, popular REST clients come with built-in features for storing, sharing, and syncing collections. However, these functionalities can sometimes be more elaborate or proprietary, leading to complications in workflows that favor simplicity and integration with existing version control systems like Git.

For teams managing numerous microservices—each residing in its own repository—the ideal setup involves maintaining test collections directly within each repository. This approach ensures versioned, portable, and easily accessible test scripts. Consequently, the team seeks a REST client that allows:

• Saving collections directly to designated local folders within each microservice’s repository
• Syncing collections automatically with the local file system
• Managing collections via standard Git workflows without proprietary cloud integrations or magic

Existing Limitations and Desired Features

Many available REST clients offer cloud-based collection sharing, collaboration features, or proprietary storage solutions. While useful in certain contexts, these features may introduce unnecessary complexity or dependency on external services. For this scenario, simplicity and direct file system management are paramount.

Ideal Solutions and Recommendations

While no single REST client currently on the market may fully tick all these boxes out of the box, certain tools and configurations can meet these requirements:

1. Postman with Local Export/Import: Though Postman primarily relies on its cloud features, it allows exporting collections as JSON files. These can be stored directly within repositories and versioned using Git, enabling straightforward management. However, manual export/import may be needed unless automation is set up.

2. Insomnia Designer and Insomnia Core: Insomnia supports exporting collections as files, which can be stored and versioned locally. Insomnia’s workspace files are stored as JSON and can be integrated into Git repositories, facilitating collaboration via standard version control.

3. VS Code Extensions: Extensions like REST Client (by Huachao Mao) enable writing and running HTTP requests in plain text files (.http or .rest), stored directly within project folders. This approach offers direct control over collection files and seamless integration with Git.

4. Custom Scripting and Automation: Building simple scripts to fetch, save, and synchronize collection files can streamline
