# TODO app with Golang functions and Redis
## Switch to correct context
- `fn use context `
- `fn ls apps`
## Create an application
`fn create app --annotation oracle.com/oci/subnetIds='[]' --config REDIS_HOST=your-redis-ip --config REDIS_PORT=your-redis-port todoapp`
### To point to a different Redis instance...
... execute below commands to update the app configuration
`fn config app todoapp REDIS_HOST your-redis-ip` and `fn config app todoapp REDIS_PORT your-redis-port`
## To deploy your functions...
Clone this repository and change into the directory - `cd fn-redis-todoapp`
To deploy all the functions in one go - `fn -v deploy --app todoapp --all`
You can choose to deploy one function at a time. You can do so by changing into the function directory and invoking the `fn deploy` command. For e.g. to deploy the create todo function - `cd create` and then deploy with `fn -v deploy --app todoapp`
Once the functions have been deployed, you can test out the CRUD capabilities
## Create TODOs
- `echo -n 'do this' | fn invoke todoapp createtodo`
> Expected response - `{"Status":"SUCCESS","Message":"Created TODO with ID 1", "Todoid":"1"}`
- `echo -n 'do that' | fn invoke todoapp createtodo`
### check TODOs
Use Redis in Docker (or install `redis-cli` locally) - `docker run --rm redis redis-cli -h 129.213.91.171 -p 6379 hgetall todo:1` (repeat same for other TODOs with Ids `2` and so on....)
You should see
todoid
2
title
do that
completed
false
## Get TODOs
### get all TODOs
`fn invoke todoapp gettodos`
You should see JSON output
[
{
"Todoid": "2",
"Title": "do that",
"Completed": "false"
},
{
"Todoid": "1",
"Title": "do this",
"Completed": "false"
}
]
### get completed TODOs
`echo -n 'completed' | fn invoke todoapp gettodos`
You will get an empty `[]` array since all the TODOs are pending (see next)
Check in Redis `docker run --rm redis redis-cli -h 129.213.91.171 -p 6379 lrange todos:completed 0 10`
> Expect an empty reply
### get pending TODOs
`echo -n 'pending' | fn invoke todoapp gettodos`
You should see JSON output
[
{
"Todoid": "2",
"Title": "do that",
"Completed": "false"
},
{
"Todoid": "1",
"Title": "do this",
"Completed": "false"
}
]
Check in Redis `docker run --rm redis redis-cli -h 129.213.91.171 -p 6379 lrange todos:pending 0 10`

## Toggle TODO (complete or pending)
### mark completed
`echo -n '{"todoid": "1", "completed":"true"}' | fn invoke todoapp toggletodo`
Expected response - `{"Status":"SUCCESS","Message":"Toggled TODO with ID 1 to true"}`
it should show up in completed list - `echo -n 'completed' | fn invoke todoapp gettodos`
[
{
"Todoid": "1",
"Title": "do this",
"Completed": "true"
}
]
it should NOT show up in pending list - `echo -n 'pending' | fn invoke todoapp gettodos`
[
{
"Todoid": "2",
"Title": "do that",
"Completed": "false"
}
]
Check in Redis `docker run --rm redis redis-cli -h 129.213.91.171 -p 6379 lrange todos:completed 0 10`

Check in Redis `docker run --rm redis redis-cli -h 129.213.91.171 -p 6379 lrange todos:pending 0 10`

Responses will be in-line with above results
### mark pending
`echo -n '{"todoid": "1", "completed":"false"}' | fn invoke todoapp toggletodo`
Expected response - `{"Status":"SUCCESS","Message":"Toggled TODO with ID 1 to false"}`
it should NOT show up in completed list - `echo -n 'completed' | fn invoke todoapp gettodos`
it should show up in pending list - `echo -n 'pending' | fn invoke todoapp gettodos`
[
{
"Todoid": "2",
"Title": "do that",
"Completed": "false"
},
{
"Todoid": "1",
"Title": "do this",
"Completed": "false"
}
]
## Edit TODO function (update title)
`echo -n '{"todoid": "2", "title":"new title"}' | fn invoke todoapp edittodo`
Expected response `{"Status":"SUCCESS","Message":"Updated title for TODO 2"}`
Confirm - `fn invoke todoapp gettodos`
JSON response with updated title for TODO
[
{
"Todoid": "2",
"Title": "new title",
"Completed": "false"
},
{
"Todoid": "1",
"Title": "do this",
"Completed": "false"
}
]
## Delete TODO function
`echo -n '1' | fn invoke todoapp deletetodo`
Response `{"Status":"SUCCESS","Message":"Deleted TODO 1"}`
Confirm - `fn invoke todoapp gettodos`
JSON reponse with TODO `1` removed
[
{
"Todoid": "2",
"Title": "new title",
"Completed": "false"
}
]
