Todo App V2

About

This is the 2nd iteration of the Todo App as part of my onboarding process with LawAdvisors Ventures. This readme file is still a work in progress and I intend to put my thoughts and decisions I made on this readme file.

My Idea about the Program

I imagine the app having 2 sub apps:

• Client - Liveview frontend
• Todo API - stores the Users, Lists and Todos tables

For the Todo API, I made the following routes available:

• GET - /lists
• GET POST PUT DELETE - /lists/:list_id
• GET - /lists/:id/todos
• GET POST PUT DELETE - /lists/:id/todos/:todo_id
• POST - /api/registration
• POST DELETE - /api/session
• POST - /api/session/renew

For the Client, I decided to

• create the liveview app from scratch
• use pow for the user logins
• use tesla as the http toolkit

My Progress

Here are the mix commands I used to create the projects:

• Todo API:
  • mix phx.new todo_api --no-html --no-assets --no-live --no-dashboard
  • mix phx.gen.json Lists List lists user_id:integer list_name:string
• Client:
  • mix phx.new todo_client

I was able to finish the version 2 of the Todo API plus along with the tests on both the APIs and Controllers of Todos and Lists.

Implemented the changes suggested by Ken and Pao.

Docker is now working.

Running the project

1. Go to todo_client directory and then run the following commands:

• docker-compose build
• docker-compose up

2. Do the same thing in the client directory
3. In case an error is encountered regarding post
4. Open a separate tab for todo_client and client directories, and then run the following command:

• docker-compose exec web mix ecto.setup

Optional Steps in case client is not able to communicate with todo_api:

1. While the docker containers are up, run the command below and get the container ids

• docker ps

2. Run the following command to check if client can ping todo_api:

• docker exec [client container id] ping [todo_api container id] -c2

Running the command will show something like:

PING 70886e53cc97 (192.168.64.2): 56 data bytes 64 bytes from 192.168.64.2: seq=0 ttl=64 time=0.060 ms 64 bytes from 192.168.64.2: seq=1 ttl=64 time=0.079 ms

--- 70886e53cc97 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0.060/0.069/0.079 ms

Copy the ip address of the todo_api (i.e. 192.168.64.2)

3. Go to client > lib > client, and open the following files:

• sessions.ex
• registrations.ex
• todos.ex
• lists.ex

2. Replace http://localhost:4000 with the ip address (i.e. 192.168.64.2:4000)
3. Run the following commands in client directory:

• docker-compose build
• docker-compose up

Bugs I am aware of

• The user is not automatically logged out after the session expires (approx. 30 minutes)
