Devise vs Postman: What are the differences?

What is Devise? Flexible authentication solution for Rails with Warden. Devise is a flexible authentication solution for Rails based on Warden.

What is Postman? Only complete API development environment. Postman is the only complete API development environment, used by nearly five million developers and more than 100,000 companies worldwide.

Devise can be classified as a tool in the "User Management and Authentication" category, while Postman is grouped under "API Tools".

Some of the features offered by Devise are:

  • Is Rack based
  • Is a complete MVC solution based on Rails engines
  • Allows you to have multiple models signed in at the same time

On the other hand, Postman provides the following key features:

  • Compact layout
  • HTTP requests with file upload support
  • Formatted API responses for JSON and XML

"Reliable" is the primary reason why developers consider Devise over the competitors, whereas "Easy to use" was stated as the key factor in picking Postman.

Devise is an open source tool with 19.9K GitHub stars and 4.74K GitHub forks. Here's a link to Devise's open source repository on GitHub.

PedidosYa, Movielala, and Webedia are some of the popular companies that use Postman, whereas Devise is used by StackShare, Movielala, and DeveloperTown. Postman has a broader approval, being mentioned in 1725 company stacks & 2166 developers stacks; compared to Devise, which is listed in 56 company stacks and 30 developer stacks.

    #QA
    #Api
    #Documentation

    We just launched the Segment Config API (try it out for yourself here) — a set of public REST APIs that enable you to manage your Segment configuration. A public API is only as good as its #documentation. For the API reference doc we are using Postman.

    Postman is an “API development environment”. You download the desktop app, and build API requests by URL and payload. Over time you can build up a set of requests and organize them into a “Postman Collection”. You can generalize a collection with “collection variables”. This allows you to parameterize things like username, password and workspace_name so a user can fill their own values in before making an API call. This makes it possible to use Postman for one-off API tasks instead of writing code.

    Then you can add Markdown content to the entire collection, a folder of related methods, and/or every API method to explain how the APIs work. You can publish a collection and easily share it with a URL.

    This turns Postman from a personal #API utility to full-blown public interactive API documentation. The result is a great looking web page with all the API calls, docs and sample requests and responses in one place. Check out the results here.

    Postman’s powers don’t end here. You can automate Postman with “test scripts” and have it periodically run a collection scripts as “monitors”. We now have #QA around all the APIs in public docs to make sure they are always correct

    Along the way we tried other techniques for documenting APIs like ReadMe.io or Swagger UI. These required a lot of effort to customize.

    Writing and maintaining a Postman collection takes some work, but the resulting documentation site, interactivity and API testing tools are well worth it.

    OmniAuth

    We use OmniAuth with Devise to authenticate users via Twitter, GitHub, Bitbucket and Gitlab. Adding a new OmniAuth authentication provider is basically as easy as adding a new Ruby gem!

    The only drawback I could see is that your OmniAuth+Devise OmniauthCallbacksController redirection logic can easily get hairy over time. So you have to be vigilant to keep it in check.

    Postman

    I use Postman because of the ease of team-management, using workspaces and teams, runner, collections, environment variables, test-scripts (post execution), variable management (pre and post execution), folders (inside collections, for better management of APIs), newman, easy-ci-integration (and probably a few more things that I am not able to recall right now).

    Secure Membership Web API backed by SQL Server. This is the backing API to store additional profile and complex membership metadata outside of an Azure AD B2C provider. The front-end using the Azure AD B2C to allow 3rd party trusted identity providers to authenticate. This API provides a way to add and manage more complex permission structures than can easily be maintained in Azure AD.

    We have .Net developers and an Azure infrastructure environment using server-less functions, logic apps and SaaS where ever possible. For this service I opted to keep it as a classic WebAPI project and deployed to AppService.

    Insomnia REST Client
    Insomnia REST Client

    We've tried a couple REST clients over the years, and Insomnia REST Client has won us over the most. Here's what we like about it compared to other contenders in this category:

    • Uncluttered UI. Things are only in your face when you need them, and the app is visually organized in an intuitive manner.
    • Native Mac app. We wanted the look and feel to be on par with other apps in our OS rather than a web app / Electron app (cough Postman).
    • Easy team sync. Other apps have this too, but Insomnia's model best sets the "set and forget" mentality. Syncs are near instant and I'm always assured that I'm working on the latest version of API endpoints. Apps like Paw use a git-based approach to revision history, but I think this actually over-complicates the sync feature. For ensuring I'm always working on the latest version of something, I'd rather have the sync model be closer to Dropbox's than git's, and Insomnia is closer to Dropbox in that regard.

    Some features like automatic public-facing documentation aren't supported, but we currently don't have any public APIs, so this didn't matter to us.

    If you're building an API service, this Chrome extension is a must-have. It'll let you ping your endpoints using a nice clean UI that's built right into Chrome. You can also share your previous requests - a simple way to 'document' your API if you're short on time.

    If someone is having trouble shipping data to the Knowtify API, I almost always share my postman collection. Working through the issue from there is typically pretty easy.

    Postman is a powerful tool for performing integration testing with your API. It allows for repeatable, reliable tests that can be automated and used in a variety of environments and includes useful tools for persisting data and simulating how a user might actually be interacting with the system

    We use Postman in conjunction with our universal REST-API "JCVortex". Postman makes testing edge-cases hassle-free and lets testing look easy. Postman was also a great help to explore the Mojang-API, that we are dependent on, because it is the central repository for minecraft-account-data.

    I use it for testing my Web Api. It's a easy tool for interacting with a RESTFul API and provides great tools for organizing requests. The Newman tool is great for allowing your tests to run in a CI/CD pipeline.

    We use Postman for all our API testing. Postman is invaluable. We would like to have a team licence so that we can use shared work spaces and test collections.
