## recent changes
- v0.23.6
- fix custom render component visibiliy when column scrolls
- v0.23.5
- infinite rearrangement workaround ; [repro](https://codesandbox.io/s/github/devel0/react-ws-canvas/tree/infinite_rearrange_repro/example) start sample5 and size height of the window like the grid then add items until last in the grid will start infinite rearrange
- v0.23.4
- added margin when wrap custom rendere objects
## issues and improvements roadmap
- can't deselect cell ( a better negative selection should implement with a class that implements a contains operator that matches in order selection pattern, for example select all then deselect a cell )
- smooth scroll ( actually scroll by row and col and not partial by pixel )
- a complete refactoring with better state management ( collect all feature currently available and rewrite the code with better modularization and functional correspondance )
## features
- **canvas based** high performance datagrid ( able to scroll with ease millions of rows maintaining immediate cell focus and editing features )
50000 rows x 200 cols example ( [LIVE EXAMPLE](https://codesandbox.io/s/github/devel0/react-ws-canvas/tree/master/example) : click *EX1* button )
- **direct cell editing**, just click on a cell then type, hit ENTER or arrows keys to move next ( [native cell types][1] )
- "text": type text to change cell ; CANC to clear cell ; CTRL+C / CTRL+V to copy/paste
- "boolean": toggle boolean with keyboard space when cell focused
- "date", "time", "datetime": smart date insertion ( typing 121030 results in 12/10/2030 ) browser locale supported
- "number": sci numbers ( typing 12e-3 results in 0.012 displayed ) browser locale support for decimal separators
- [properties default values][22]
- [cell or row][2] selection mode
- selection [mode multi][9]
- frozen [rows, cols][3]
- [wrap][21] text cells ( [helper][121] )
- rows and cols numbering can be [shown or hidden][5]
- if column numbering visible automatic sort can be customized through [less-than-op][6] ( [helper][106] )
- [column click behavior][12] can be full column select, column toggle sort or none to disable sort/select behavior
- [column header][15] can be customized ( [helper][115] )
- canvas size can be specified through width, height ( [fullwidth][26] option available )
- column width can be changed intractively using mouse
- column width [autoexpand][16]
- column custom [initial sort][18] ( *note*: prepareCellDataset, rowSetCellData, commitCellDataset must defined to make sort working ); also see [example6][36] for tip about ensure initial sort on subsequent datasource applications
- data getter/setter can follow a [worksheet][7] or a [db record type][8] ( [example of nested field][28] using [getFieldData][29] and [setFieldData][30] methods)
- data [filter global][129]
- optional dataset on external object with [ds rows getter mapper][32] useful in some circumstance when need to preserve rows array object ref
- [api][10] and [handlers][27] available for control interactions ( [example][11] ) ; props can be accessed [inversely][31] through api; retrieve list of selected row idxs [example][38]
- each individual cell [custom edit][13] ( F2 ) control can be customized also in [column helper][113] ( [example][24] : through keyboard F2, arrows then enter ) ; cell [editing/edited][128] also in [column helper][127]
- custom multi select with material-ui ( [example][35] )
- custom date picker with material pickers ( [example][37] )
- custom color picker with **custom render** ( [example][130] ) ; note: wrapText will use custom component height to *autoresize row height* ; *filter* can work as text mode defining renderTransform
- cell [background][19], [font and color][119], [readonly mode][126] customization and [text align][25] also with [helper][125]
- container [height min][23] and canvas [styles][20]
- each individual [cell type][14] can be customized ( [column helper][114] )
- clipboard copy to/from spreadsheet with ctrl-c and ctrl-v or [api][34] ( [example api][33] )
- support mobile touch scrolling rows, cols and scrollbars

## todo
## quickstart
- create react app
eventually install create-react-app
```sh
npm install -g create-react-app
```
```sh
create-react-app test --template typescript
cd test
yarn add react-ws-canvas
```
- edit `App.tsx` as follows
```ts
import React, { useState, useEffect } from 'react';
import { WSCanvas, useWindowSize, WSCanvasColumnClickBehavior } from 'react-ws-canvas';
const AppQuickStart: React.FC = () => {
const [rows, setRows] = useState([]);
const winSize = useWindowSize();
const ROWS = 500000;
const COLS = 20;
useEffect(() => {
const _rows = [];
for (let ri = 0; ri < ROWS; ++ri) {
const row = [];
for (let ci = 0; ci < COLS; ++ci) {
row.push("r:" + ri + " c:" + ci);
}
_rows.push(row);
}
setRows(_rows);
}, []);
return row[colIdx]}
prepareCellDataset={() => rows.slice()}
commitCellDataset={(q) => setRows(q)}
rowSetCellData={(row, colIdx, value) => row[colIdx] = value}
/>;
}
export default AppQuickStart;
```
- run the app
```sh
yarn start
```
## examples list
| example | description |
|---|---|
| [quickstart](example/src/App.quickstart.tsx) | 500000 x 20 grid with minimal props |
| [Sample1](example/src/Sample1.tsx) | 50000 x 200 grid with frozen row/col, filter, custom column width |
| [Sample2](example/src/Sample2.tsx) | 5000 x 6 grid db-record-like column mapping, initial sort, custom sort, api onMouseDown, global filter, cell changing/changed |
| [Sample3](example/src/Sample3.tsx) | 5000 x 7 grid db-record-like, data interact del/change row, custom cell editor, rowHover |
| [Sample4](example/src/Sample4.tsx) | add/insert/del/move/currentRealRowSel rows using api |
| [Sample5](example/src/Sample5.tsx) | custom multi select with material-ui ; custom render chip with color picker |
| [Sample6](example/src/Sample6.tsx) | resetView behavior to force sync ds ; resetSorting and resetFilters resetView arguments |
## tips
**prevent direct editing on editor customized cells**
customize onPreviewKeyDown event handler on datagrid and preventDefault for matching cell
```ts
onPreviewKeyDown={(states, e) => {
if (states.props.columns && api && api.isDirectEditingKey(e)) {
const fieldname = states.props.columns[states.state.focusedCell.col].field;
if (fieldname === "colname") {
//const row = states.props.rows[states.state.focusedCell.row];
e.preventDefault();
}
}
}}
```
## how to contribute ( quickstart )
- clone repo
```sh
git clone https://github.com/devel0/react-ws-canvas.git
```
- open vscode
```sh
cd react-ws-canvas
code .
```
- from vscode, open terminal ctrl+\` and execute example application ( this allow you to set **breakpoints** directly on library source code from `lib` folder )
```sh
cd example
yarn install
yarn start
```
- start chrome session using F5
## local deploy
- from library
```sh
cd lib
yarn build && yalc publish
```
- from your project
```sh
npm uninstall react-ws-canvas --save && yalc add react-ws-canvas && npm install
```
## how this project was built
```sh
yarn create react-app react-ws-canvas --template typescript
```
Because I need a library to publish and either a working example to test/debug the library project structured this way:
- `/package.json` ( workspaces "example" and "lib" )
- `/example` ( example and library sources )
- `/example/package.json`
- `/example/.env` with BROWSER=none to avoid browser start when issue `yarn start` because I use F5 from vscode to open debugging session
- `/example/lib` ( library source codes )
- `/lib` ( library publishing related files )
- `/lib/package.json`
- `/lib/rollup.config.json` ( specifically `input: '../example/src/lib/index.tsx', ` )
- `/lib/tsconfig.json` ( specifically `"rootDirs": ["../example/src/lib"],` and `"include": ["../example/src/lib"],` )
- `/lib/prepatch-and-publish` ( helper script to prepatch version and publish with README.md )
## development notes
- **key notes** (old)
- [cs.width and cs.height][1508] variables represents [canvas size][1509] and used as starting point for [calculations][1510]
- [stateNfo, viewMap, overridenRowHeight][1500] are kept separate because stateNfo must light because frequently updated while viewMap and overridenRowHeight can be heavy struct for large grids
- [view][1501] mapping have a size less-or-equal than rowsCount depending on [filtering][1502] and the order of view may different depending on sorting
- some methods work with [real cells][1503] ( the same as user configure through getCellData, setCellData ), some other methods works with [view cells][1504] that is an internal representation convenient to deal on what-you-see-is-what-you-get
- [real and view coords][1505] can be transformed between
- [mkstates][1506] is an helper used primarly by [handlers][1507] to ensure callback uses synced state
- **TODO**
- type 'select' for cell with combobox integrated
- date picker when F2 (or double click) on date type cell
- isOverCell should true on last row when showPartialRows
- deployment
- remove any `from "react-ws-canvas";`
