CRUD

It is important to learn the different status codes so you know what to send/ what ones you are being sent mean and also its good to go again over linking up with a database to be sure you’ve got it clear.

Status Codes Based on REST Methods

An HTTP status code is a number between 100 and 600 that is part of an HTTP response. The first digit denotes the class of the response and it comes with a reason phrase.

Status classes:

• 100-199: Informational - part of the request has been recieved and the server will attempt to comply.
• 200-299: Success - the request was accepted.
• 300-399: Redirection - the resource requested is not available at the expected location, and the client must redirect.
• 400-499: Client Error - an invalid request was sent to the server.
• 500-599: Server Error - the server is overwhelmed or unreachable.

CRUD (create, read, update, delete) is a model defining the most basic API actions for persistant storage.

• Create
  • 200 - OK
  • 201 - Created
  • 202 - Accepted
  • 303 - See Other
• Read
  • 200 - OK
  • 206 - Partial Content
  • 300 - Multiple Choices
  • 304 - Not Modified
  • 307 - Temporary Redirect
  • 308 - Permanent Redirect
• Update
  • 200 - OK
  • 202 - Accepted
  • 204 - No Content
• Delete
  • 200 - OK
  • 202 - Accepted
  • 204 - No Content
• API Changes
  • 307 - Temporary Redirect
  • 308 - Permanent Redirect
• Multiple Endpoints for One Resource
  • 308 - Permanent Redirect

Errors are another important section of status codes

• Wrong URL
  • 307 - Temporary Redirect
  • 308 - Permanent Redirect
  • 404 - Not Found
  • 405 - Method Not Allowed
  • 406 - Not Acceptable
  • 410 - Gone
  • 414 - Request URI Too Long
  • 501 - Not Implemented
• No Permissions
  • 401 - Unauthorized
  • 403 - Forbidden
  • 404 - Not Found

1. 100s, the server is acknowledging your request - 200s, the server has accepted your request - 300s, the server needs you to go somewhere else - 400s, the client has messed something up - 500s, the server has messed something up.
2. 202 is Accepted
3. 308 is a permanent redirect
4. If an update didn’t return data, you would return 204.
5. If a resource used to exist, but no longer does you would use 410.
6. Forbidden is 403

Build a Rest API

1. Because we don’t want the database link pushed to github.
2. Middleware runs between when the server recieves a request and passes it to a route.
3. Lets the server accept json as a body.
4. It is a parameter.
5. Patch only updates based on what is passed in, while Put updates everything.
6. You put in a default key in the object.
7. 500 meanse there’s an error on the server.
8. 201 meanse successfully created an object, 200 is a more generic success.
