Q2.Unit test for Q2 it in src/jumble/jumble.service.spec.ts, run the following code to test it.
$ npx jest jumble.service.spec.tsYou can also run the following in root directary to run all the test cases.
$ npm run testQ3.I use the libraries of nestjs to setup the service, and use class-transformer and class-validator to valid the params and body to test if n is a string that can be transformed to a valid number and if message is not empty.
Q4.although Q4 says I can choose 1 option to deploy.I accomplish all the options.For 1st please see my Dockerfile. For 2nd, please visit http://54.79.167.146:3001. for 3rd, can run command npm run start:dev locally.
All 3 ways are OK.I recommend you to use 2nd, visit http://54.79.167.146:3001. If you want to test the POST api, visit http://54.79.167.146:3001/0 with the body { "message": "test 123!" }
Q5.I find 2 ways can implement a rate limiter mechanism, 1 is use middleware with the logic in src/middlewares/rate-limiter.middleware.ts. The other one is use the libary of @nestjs/throttler. I tested both, both are OK.I comment the middleware solution and use @nestjs/throttler
