bundle is a quick and easy way to bundle your projects, minify and see it's gzip size. It's an online tool similar to bundlephobia, but bundle does all the bundling locally on you browser and can treeshake and bundle multiple packages (both commonjs and esm) together, all without having to install any npm packages and with typescript support.

If there is something I missed, a mistake, or a feature you would like added please create an issue or a pull request and I'll try to get to it. You can contribute to this project at okikio/bundle.

You can join the discussion on Github discussions or Twitter.

You can now use search queries in bundle, all you need to do is add this to the url
?q={packages}&treeshake={methods to treeshake}

e.g.
You want react, react-dom, vue, and @okikio/animate, but only want the Animate and toStr methods exported from @okikio/animate.

You would add this to the url bundlejs.com/?q=react,react-dom,vue,@okikio/animate&treeshake=[*],[*],[*],[{Animate,toStr}]

MockServer features and specs

  • Flexibility
    MockServer provides extensive support for HTTP and HTTPS as well as customizable responses, which allows developers to simulate various scenarios and behaviors in a flexible manner.
  • Scriptable Expectations
    You can define expectations using Java, JavaScript, JSON, and YAML, enabling you to control responses in a programmatic way for more complex testing scenarios.
  • Ease of Integration
    MockServer can be easily integrated with various build tools and CI/CD pipelines, which streamlines the testing process and makes it more efficient.
  • Extensive Documentation
    MockServer comes with comprehensive documentation that includes usage examples, configuration guides, and API references, which helps in decreasing the learning curve.
  • Support for Unit and Integration Testing
    The tool supports both unit and integration testing, making it versatile for testing different levels of a system in isolation.

Possible disadvantages of MockServer

  • Performance Overhead
    Running MockServer can introduce performance overhead, especially in resource-constrained environments, which may affect the speed of the tests.
  • Complex Configuration
    While powerful, the configuration can become complex, particularly for more elaborate mock scenarios, leading to a steeper learning curve for newcomers.
  • Dependency Management
    When used in a Java environment, managing dependencies can become cumbersome, particularly if there are version conflicts with other libraries in the project.
  • Requires Java Runtime
    MockServer requires a Java Runtime Environment, which can be a limitation if your development environment or CI/CD pipeline does not support Java.
  • Limited Community Support
    While it has good official documentation, the community support around MockServer is not as extensive as some other tools, which may limit the availability of third-party plugins and extensions.

  • MockServer: Easy mocking of any system you integrate (HTTP or HTTPS)
    There are several strategies to solve this kind of challenge, but today we will see MockServer as a tool to resolve it. - Source: dev.to / almost 2 years ago
  • Please recommend a good API Mocking tool
    The open-source examples are mockoon, mock-server.com, etc. Source: about 3 years ago
  • Testing with MockServer
    I've just found out MockServer and it looks awesome ๐Ÿคฉ so I wanted to check it out repeating the steps of my previous demo WireMock Testing which (as you can expect) uses WireMock, another fantastic tool to mock APIs. - Source: dev.to / about 4 years ago
  • How to unit test successful Oauth requests of 3rd party API's?
    I tend to use MockServer. With MockServer you can define inputs, so you can say that the request should look like this with that URL, etc etc. That way you can verify that the request looks okay. Source: over 4 years ago

  • Show HN: Duper โ€“ The Format That's Super
    I think a neat route would be to use this as an authoring plugin in VS Code, like prettier: write Duper (or JSON5, or whatever), and then downlevel it to regular json automatically when pressing cmd-s. You wouldn't get to keep your comments (or they could be transformed to { "//": "comment text" }). Outside of that, it's tough to compete with JSON in the "human readable unschematized serialization format" market,... - Source: Hacker News / 9 months ago
  • I Built the Same App 10 Times: Evaluating Frameworks for Mobile Performance
    React's bundling system and published packages has gotten noticeably more complicated over time. First, there's the separation between the generic cross-platform `react` package, and the platform-specific reconcilers like `react-dom` and `react-native. All the actual "React" logic is built into the reconciler packages (ie, each contains a complete copy of the actual `react-reconciler` package + all the... - Source: Hacker News / 9 months ago
  • Zod 4
    These numbers don't reflect anything useful. This is the total size of the code in the package, most of which will be tree-shaken. In Zod's case, the package now contains three independent sub-libraries. I recommend plugging a script into bundlejs.com[0] to see bundle size numbers for a particular script [0] https://bundlejs.com. - Source: Hacker News / about 1 year ago
  • PackagePhobia โ€“ Find the cost of adding a new dev dependency to your project
    [bundlejs](https://bundlejs.com/) is the better alternative to check your dependency sizes with. - Source: Hacker News / over 1 year ago
  • ESM & CJS: The subtle shift in bundlejs' behaviour
    I was closing out some long lived issues over on bundlejs, when issue #50 reminded me of the ongoing debate about how bundlejs should handle the ESM and CJS packages. - Source: dev.to / about 3 years ago
