Grid won't update when redux is updated from uploaded layouts
Procedures to reproduce
1, switch to branch navbar
2. npm run start
3. click download to save a snapshot of the current layout.
4. randomly change layout
5. click upload to load the previous saved layout
A possible solution
Use versioning: feed key={timestamp}
so that React will be forcibly re-create the grid. This may solve to problem (we have to try...)

backend-independent state shape
Currently we use redux-firestore and react-redux-firebase to connect to data sources, and the state is in the shape of
{
"firebase": {
"data": { ... },
...
},
"firestore": {
"data": { ... },
...
},
...
}
We should redesign the state shape, as it doesn't make sense If the data source is changed.
Todos
- editor (react codemirror)
- remove chart
- lock chart
- navbar (import export)
- aggregate
- undo/redo
create test backend server
- Create a test backend server that generates fake data in a given pattern at a given frequency.
- The configuration file for Firestore should be language independent.
Configuration format
For human-editable configuration format
# chart-id should be a unique, valid name
chart:
# (required)
title: "Title"
# (optional)
description: "Some description"
# Multiple sources (optional)
sources:
- name: "source-name"
type: "chart type"
- name: "source-name"
type: "chart type"
- name: "source-name"
type: "chart type"
# Data is filtered to be in the range of [start, end]
# Both start & end is in RFC3339 format
# (optional, default to the first data)
# If start is negative, it means the offset from end
start: -3600
# (optional, default to now)
end: 2018-07-28T07:32:00Z
# (optional, only useful when agg_func is set)
segment: 60
# (optional)
agg_func: "average"
the structure of Firestore database
Currently (as in PR #3 ) each sequence is store in one document, in the format of
{
name: '<seq name>',
values: [
{
timestamp: '<timestamp>',
value: '<value>'
},
...
]
}
and all documents live in a single collection. I think we can create different collections for development and production environments.
Any idea or comment about the format of sequences? Is there any other information we need to store?
