Nestjs return status code

Nest NestJS is a framework for building efficient, scalable Node. Nest provides a level of abstraction above these common Node.

This allows developers the freedom to use the myriad of third-party modules which are available for the underlying platform. In recent years, thanks to Node. This has given rise to awesome projects like AngularReact and Vuewhich improve developer productivity and enable the creation of fast, testable, and extensible frontend applications.

However, while plenty of superb libraries, helpers, and tools exist for Node and server-side JavaScriptnone of them effectively solve the main problem of - Architecture. Nest provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications.

The architecture is heavily inspired by Angular. To get started, you can either scaffold the project with the Nest CLIor clone a starter project both will produce the same outcome. To scaffold the project with the Nest CLI, run the following commands. This will create a new project directory, and populate the directory with the initial core Nest files and supporting modules, creating a conventional base structure for your project.

Creating a new project with the Nest CLI is recommended for first-time users. We'll continue with this approach in First Steps. To install the JavaScript flavor of the starter project, use javascript-starter. You can also manually create a new project from scratch by installing the core and supporting files with npm or yarn. In this case, of course, you'll be responsible for creating the project boilerplate files yourself. Nest is an MIT-licensed open source project.

nestjs return status code

There is no way to pass the execution to the default exception handler on some condition when using custom exception filter.

I'm creating single page application and want to return an index. TL;DR: I wanted to use exception filters to just map some internal exceptions to external user-friently HttpException s, and let Nest handle them the usual way -- but if I do that, the new exceptions are not handled by Nest at all. On internal calls from other modules, I most often want to handle this exception in some way, but if it happens directly in a controller, I want to catch it and throw a NotFoundException to have a correct response status code.

So I've made this little filter, hoping it will do the job:. Current behavior: The new, mapped error is not handled by the "built-in" exception handler, which transforms HttpException s to meaningful responses; instead nest fails badly -- there is an unhandled exception logged, and no response at all on the client side not even the usual internal server error :. Question: is there some recommended way to achieve this, without manually constructing the response in my custom exception handler or some other place?

I've experienced statusCode always being in the interceptor. The following is not an elegant solution, but pushing the getResponse to the end of the call stack using setTimeout has solved this issue for me:.

It seems like the interceptor is invoked before the final response code is set on the reponse object. Hmm I think using the request and response objects from express or fastify and attach once listeners might be the more elegant solution then.

I am worried it's not as generic and and elegant as hoped, but I hope you will ultimately come up with the best solution in the request prometheus metrics module. Consider the following example:. I created an ETagInterceptor that calculates the Etag of the response to be send back to my client.

The API then processes the request and creates the response. If the new etag matches the if-none-match header, the content shall be removed i. I thought it would be a good idea to apply a Global Interceptor for this scenario, like so shortened version :.

So for my use-case, how is it not possible to set the status code? I read the answer from above:.

I believe this is a question better fitted for StackOverflow, but you should be able to do context. The following is not an elegant solution, but pushing the getResponse to the end of the call stack using setTimeout has solved this issue for me: return call. Actually, it's impossible for a few reasons: sometimes response status codes are dependent on exceptions and exception filters are executed after interceptors, global response controller's logic is the last step performed just before sending a final result through the network that's the place where default status codes come in.

Can you share how you currently enrich your services with prometheus metrics? Consider the following example: I created an ETagInterceptor that calculates the Etag of the response to be send back to my client.

After installing the CLI, navigate to your working folder and run the following command to generate a project:. Next, you can navigate inside your project's root folder and run a local development server using the following commands:.

At this point, you should only see a blank page with the Hello World! For the sake of better organization, let's create a module that will contain the CRUD functionality of this application. Open a new terminal, navigate to the root folder of your project and run the following command to create a module named contacts :.

Next, let's create a service that will encapsulate all CRUD operations. In your terminal, run the following command:. Next, let's create a controller, we'll also call it contacts ant It will be created inside the contacts module:. Our method will simply return the This action will return contacts sentence for now. Notes : All the routes that belong to this controller will be prefixed by the contacts path which is passed to the Controller decorator before the controller class.

We named the root action of this controller as index but you are free to give your action any valid name you choose since the name of the route's path will be taken from the Get decorator. The Get decorator before the index method instructs Nest to create an endpoint for the corresponding route path and then map any coming request to the index handler. Since we've specified a prefix for every route of the contacts controller as contactsNest will send every GET request to the index method.

Now, before proceeding to add any controller logic, let's add a database to our application. For the sake of simplicity we'll be using a SQLite database. As the time of this writing, sqlite3 v4. We simply import TypeOrmModule and we use the forRoot method to pass a configuration object this is the same object that you would normally pass to the standard createConnection method of TypeORM. After configuring TypeORM, let's now create our first entity.

In your terminal, run the following command from the root of your project:. Now TypeORM will recognize the Contact entity and will synchronize the database accordingly by creating a contact table.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The documentation is very well written and very useful; however I think an example of serving a static file would be a huge plus. An example serving a static html file would help a lot. Yes, that's true. If you're interested in serving static files, here's a nice way to do it with fastify and fastify-static.

Then, add the following lines to:. I would love to serve both my react app and the json needed from the server! That's weird. It depends on how you configured to access the service on aws.

Have you tried with other routes to return, for example, JSON? Cspeisman it is my first time leaving a question so, let me explain: I recently started to work with Nest framewor, Until now I have couldn't do a good render. I have this:. Cspeisman object with all the data you want to put into the view using ejs template rendering. And if you create an ExeptionFilter and add it to the app.

You just need to take care of the routing on the client React, Angular, etc. Solution: comment. I recently came to the same situation where I needed to serve an SPA React from within a NestJS application that also served an express legacy application. Therefore I extended rilexus solution:. I guess we should mention that in the docs. That helped me to serve my static assets, stylings, images and js files.

Each operation must have at least one response defined, usually a successful response. JSON is the most common format for data exchange, but not the only one possible. To specify the response media types, use the produces keyword on the root level or operation level.

The global list can be overridden on the operation level. An operation typically returns one successful status code and one or more error statuses.

Each response status requires a description. For example, you can describe the conditions for error responses. GitHub Flavored Markdown can be used for rich text representation. User ID must be an integer and bigger than 0. Note that an API specification does not necessarily need to cover all possible HTTP response codes, since they may not be known in advance.

However, it is expected to cover successful responses and any known errors. By "known errors" we mean, for example, a Not Found response for an operation that returns a resource by ID, or a Bad Request response in case of invalid operation parameters. Response Body The schema keyword is used to describe the response body.

Hello, nest!

Schema can be defined inline in the operation: responses: description: A User object schema: type: object properties: id: type: integer description: The user ID. This is useful if multiple responses use the same schema. In this case, define the response schema with type: file and specify the appropriate MIME types in the produces section. To indicate the response body is empty, do not specify a schema for the response. Swagger treats no schema as a response without a body. X-RateLimit-Remaining: type: integer description: The number of requests left for the time window.

Note that, currently, there is no way in Swagger to define common response headers for different response codes or different API operations. You need to define the headers for each response individually. This is useful for error responses with the same status codes and response body.

These are just definitions that can be referenced and reused by multiple operations. FAQ Can I have different responses based on a request parameter?
