Column Full Stack Task Workflowy is an easy todo management dashboard with great structuring of these todos to incorporate and extend each specific tasks into infinite other tasks as required. https://www.workflowy.com The task is to make a simple workflowy type of an interface using React and sort of a backend to support the same using GraphQL You can have a look at the website for an exact experience, so mainly the idea being creating an interface where the user can add to-do tasks, and then in turn each of these tasks can be subdivided into more such tasks indefinitely showing them in a chain like format and so on for each of these tasks The idea is also to create a storage structure and representing the same through a React UI, in order to handle the same, a chained tree type of structure where each node/task can be further subdivided into the same You don’t have to pay much attention to the styling details just a functional approach executing the same would be good enough, you can make this interface as you would like in React and support it somewhat either through a NodeJS) approach or any way you would like using GraphQL. You need not use redux Note: It is important to use GraphQL to create queries, mutations and subscriptions to update You might choose it keep it very simple, but it’s implementation will be verified

REPLICATING WORKFLOWY

I want to start up first by thanking you the opportunity.

I also wanted to state that I was a bit in a haste to complete this and I had to clone an old github repo which I made changes to so as to give me a headstart.

To run the application locally, please ensure you have postgres installed locally as the server uses the postgres db as seen in ./server/ormconfig.json After that, use the following commands:

createdb workflowy

(This above command is used to create a postgres DB)

It will ask for password for user, please enter "test" as seen in the ./server/ormconfig.json

cd server && yarn install && yarn start

cd web && yarn install && yarn start

After this, go to localhost:3000 to view the React Application You can also see the graphql playground by going to http://localhost:4000/graphql

On the backend, I used Typecript, NodeJS (Express) and apollo-server-express, please ignore every other unused data on the backend

On the frontend, I used Typescript React, and React-Native-Web (To get display: flex by default, speed and also get some out of the box tools that RN provides easily for us. This also shows my knowledge on building scalable cross platform mobile applications). Sadly I used Redux, for only two things. To persist data on reload, and also to store two keys. (Note: I could have done this with apollo client cache but my solution would have taken me more time. I apologize for this)

ANSWERS TO THE TWO QUESTIONS

Q1. In the above task, if you also had to incorporate images/media of any kind with each of the tasks on the interface, what would you add to your current approach, you can discuss briefly

Answer: On the task interface on the server, there are three important keys;

1. id: number, which is the unique identifier of each node
2. pId: number, this is more like a parent Id that helps us know which node is the parent creator.
3. Lastly is task: string, which is a string that carries the Task message For assets like images/audio, we would have to add another key to the interface, maybe called asset. And these can be added at the time of creation by sending the file to s3 bucket or firebase storage, generating a link that will be stored in the asset key, and then this asset is also kept in users gallery (A new part of the schema), and that will make users be able to select old assets so that we don't have to upload to our storage every single time

Q2. If you are using GraphQL and Redux on your front end, how would you manage the state for such a use case, since both of them come with their own state management libraries. How would you handle the same

Answer: I think for things like "Is menu open or not?" or "User selected this language/country?", it is really overkill to try to do this with apollo. This can be done with redux. Essentially we are trying to ensure we avoid having duplicate data but at the same time ensure we do not over complicate a feature just for the sake of using apollo caching
