Inter-Process Communication
For this lab, you will make an API similar to Assignment 4. This time you will implement GET, PUT, POST, and DELETE
routes with data retrieved from a second process. You will also continue to practice your usage of redis and async / await
usage.
You will promisify the redis-client for use, and you will use all of its methods with the use of the awaitkeyword.
For this lab, you will use a worker to do all database-like operations (Create, Read, Update, and Delete). Normally, you
would only pass writes off to the worker.
You will not have to utilize a cache for this assignment
You will need to run two programs!
Running 2 Processes with your npm start command
For your npm start command, simply do something like:
"start": "node worker/index.js && node server/index.js
In order to run both at once.
For the sake of this assignment, please make only one package that has dependencies for both the worker and
server.
Your worker
You will make a file, worker.js, that performs the following:
1. When the worker starts up, it will download the dummy data
(https://gist.githubusercontent.com/philbarresi
/5cf15393d245b38a2d86ce8207d5076c/raw/d529fb474c1af347702ca4d7b992256237fa2819/lab5.json) and store it in memory,
similar to last week. NOTE: you must download this data, not hardcode it.
2. The worker should respond to a request to provide the person listed at the supplied ID
3. The worker should respond to a request to create a person with the supplied information; the response should have the
newly created person data
4. The worker should respond to a request to update a person with the supplied information; the response should have the updated person data
5. The worker should respond to a request to delete a person with the supplied ID; the response should simply indicate
that the deletion was successful.
Your Routes
You will only have 4 routes!
GET /api/people/:id
This route will publish a message to request a person from the worker, and render JSON of the person (or of an error,
should once occur)
POST /api/people
This route will publish a message to request that the worker creates a person, and render JSON of the person created (or of
an error, should once occur)
DELETE /api/people/:id
This route will publish a message to request that the worker deletes a person, and render JSON stating that the operation
completed (or of an error, should once occur)
PUT /api/people/:id
This route will publish a message to request that the worker updates a person, and render JSON of the person updated (or
of an error, should once occur)
General Requirements
1. Remember to submit your package.json file but not your node_modules folder.
2. Remember to check for errors, everywhere!
