CRUD

Status Codes Based On REST Methods

  1. In your own words, describe what each group of status code represents:

    • 100’s = Information codes that let a client know a request has been received
    • 200’s = Success codes that say a request was successful or received for processing
    • 300’s = Redirection if a resource has moved
    • 400’s = Client errors
    • 500’s = Server errors

  2. What is a status code 202?

    “Accepted” This code lets the client know the request was accepted but is being processed asynchronously and will finish being processed at some time in the future.

  3. What is a status code 308?

    “Permanent Redirect” This means the URL is no longer in use to access this resource anymore and has moved to a different URL

  4. What code would you use if an update didn’t return data to a client?

    Code 204 No Content

  5. What code would you use if a resource used to exist but no longer does?

    Code 410 Gone

  6. What is the ‘Forbidden’ status code?

    Code 403 Forbidden

REST API With Node.js, Express, & MongoDB

  1. Why do we need to pull our MongoDB database string out of our server and put it into our .env?

    You need to pull the database string out because the location of the database will vary between development and deployed environments of the application.

  2. What is middleware?

    Middleware is code that runs when the server gets a request before it is processed by the routes.

  3. What does app.use(express.json()) do?

    This enables the express server to accept JSON data.

  4. What does the /:id mean in a route?

    It is a parameter that allows you access the information in the path of the URL from the client.

  5. What is the difference between PUT and PATCH?

    PUT is used to update everything in a record while PATCH is used to make a partial change.

  6. How do you make a default value in a schema?

    You add a default attribute to the property type definition in the schema.

  7. What does a 500 error status code mean?

    It means there was an error on the server and the error is not the fault of the client.

  8. What is the difference between a status 200 and a status 201?

    Status 200 means successful but 201 further clarifies that it was successful and a new resource was created.
