title: "ADR: Handling tables"
|
|
---
|
|
|
|
## Background
|
|
|
|
We need to handle table state on different pages. Some pages do client side table handling while some other need to offload some work to the server.
|
|
Two most critical pages that we migrate to server handling are the Feature Flags page and Project Overview page.
|
|
|
|
[Table handling options](/img/handling-tables-adr.png)
|
|
|
|
Table handling consists of 4 parts:
|
|
* API call and **server side data handling**
|
|
* persistent table state in URL and localStorage (handled by the usePerisistentTableState hook)
|
|
* column definitions and **client side data handling** (handled either by react-table or custom code)
|
|
* Material-UI rendering components
|
|
|
|
Data handling consists of:
|
|
* sorting (either server or client side)
|
|
* pagination (either server or client side)
|
|
* searching (either server or client side)
|
|
* filtering (either server or client side)
|
|
* column visibility (only client side)
|
|
* row selection (only client side)
|
|
|
|
### Options
|
|
|
|
For pages with no server data handling we need `react-table` for client side data handling.
|
|
For pages with server data handling we considered two options that we implemented in a spike:
|
|
* not using `react-table` and writing minimal custom code for column visibility, data mapping and row selection.
|
|
Not much else is required since server side is doing sorting/pagination/searching/filtering
|
|
* using `react-table` with the extra cost of the library magic and writing connectors from backend data to `react-table` structures
|
|
|
|
The tradeoff is between simplicity of the pages that support server side data handling and the consistency
|
|
between the definitions of the client side and server side powered tables.
|
|
|
|
|
|
## Decision
|
|
|
|
We have decided to **favor consistency over one-off simplicity**.
|
|
Using `react-table` comes at a cost but allows to change between client and server side data handling with lesser effort. It allows to revert decisions to client side and makes the migration
|
|
to server side data handling easier.
