Postman interceptor8/8/2023 ![]() ![]() It can be used to inspect a request or transform parts of it, like the URL or headers. What is an Angular HTTP Interceptor?Īngular's HttpInterceptor is a lightweight class that can tap into an outgoing request or an incoming response. This is what makes it a viable solution to use with a Postman mock server in development. It can be configured to divert some requests to a different server, through the Angular CLI. It receives requests from the client, modifies, and diverts some of them to other servers.Īngular uses Webpack's dev-server as a proxy. What is a Proxy?Ī proxy server is a software tool that often acts as an intermediary between a client and a server. The major difference between these two options is that the proxy is applied at build-time, while the interceptor is applied at run-time. There are two popular ways that come to mind: Once you’ve decided to work with a Postman Mock Server, you then need to integrate it with the application in such a manner as to not: The Postman documentation provides more comprehensive details about collections and examples if you want to learn more. It is made up of the request and an expected response. ![]() It has its own base URL and an optional API key for added security.Ī Postman collection is a logical grouping that helps organize related requests, while a Postman example is an instance of a request in action. It provides tools and integrations that help with designing, documenting, testing, monitoring, sharing, and using APIs.Ī Postman Mock Server is a dummy API server that accepts requests to endpoints you create in a collection and returns the responses you specify in examples. ![]() Postman is a collaborative API platform that is designed to support the complete lifecycle of APIs. It might not be for every use case, but it offers a convenient way of working with mock data. You can also integrate these tools in front end applications for use in development.Ī Postman mock server is straightforward to set up and integrate with an Angular application – particularly, when it is paired with an Angular interceptor. There are multiple tools that can help with creating and using mock data, such as Postman and its mock servers. Smoother demos - just in case the real server decides to be offline.Better testing with different API response data.Some other pros of having mock data handy include: This option is especially beneficial when the feature is a must-have by the end of a sprint. If for any reason endpoint development is stalled or lags behind, despite the sprint planning, you will be faced with the question: do you build with or without the data?įortunately, there is a third option: building with mock data (which could work depending on your use case). Earlier, Postman Interceptor like apps were an additional requirement if we wanted to check browser cookies.New front end features often require back end data support – especially where new endpoints are concerned.įor example, an application that needs an authenticated user experience may need a new /authenticate endpoint. ![]() So once you install the native Postman app from here, you don't have to go looking for additional Chrome extensions like Interceptor. The latest version of the native apps has a built-in console, whichĪllows you to view the network request details for API calls. Restricted by the Chrome standards for the menu bar. Previously, users needed to use the Interceptor extension Requests that return a 300-series response from being automatically REDIRECTS OPTION: This option exists in the native apps to prevent Version of the native apps let you send headers like Origin and The Chrome app, no separate extension (Interceptor) is needed.īUILT-IN PROXY: The native apps come with a built-in proxy that you Now the recommendation is to go for native apps which are not detached from the sandboxed environment of the browser.ĬOOKIES: The native apps let you work with cookies directly. Chrome apps including Postman are being deprecated as mentioned here. ![]()
