Add a React example in TypeScript #2002
Comments
|
I would love to have a high quality wrapper for React (and Vue) as I've now created one for Angular (what I use at work) - clearly keeping gridstack neutral (plain TS) as frameworks come and go.... I don't know React, but for more advanced things (multiple grids drag&drop, nested grids, dragging from toolbar to add/remove items) is it best to let gridstack do all the DOM manipulation as trying to sync between framework and GS becomes complex quickly. This is what I've done in the Angular wrapper - GS calls back to have correct Ng component created instead of The current React & Vue use the for loop which quickly falls appart IMO (I have the same for Angular but discourage for only the simplest things (display a grid from some data, with little modification by user) |

I have the same problem, I want to know if I can make it react, I am working in a NEXTJS environment with Typescript and it is costing me a bit to implement the use of this library, with pure js it works correctly. |

I'm building a wrapper to use gridstack properly and not with a hook, which could be used like this : I'm close to achiving it but I have to be optimized and fixed for some weird rerenders I think this code can help ;) // demo.tsx
"use client";
import React, { useState } from "react";
import { GridstackAPI, GridstackItem, GridstackWrapper } from "./gridstack-wrapper";
export default function Demo() {
const [counter, setCounter] = useState(1);
const [showItem, setShowItem] = useState(false);
const [gridstackAPI, setGridstackAPI] = useState<GridstackAPI | null>(null);
return (
<>
<button type="button" onClick={() => setShowItem(!showItem)}>
{showItem ? "Hide" : "Show"} item
</button>
<button type="button" onClick={() => gridstackAPI?.column(10)}>
Decrease columns
</button>
<button
type="button"
onClick={() => {
gridstackAPI?.addWidget({
x: 1,
y: 1,
w: 2,
h: 2,
});
}}
>
Add widget
</button>
<GridstackWrapper
options={{
column: 12,
animate: true,
float: true,
margin: 0,
acceptWidgets: true,
resizable: {
handles: "all",
},
}}
setGridstackAPI={setGridstackAPI}
>
{showItem && (
<GridstackItem initWidth={2} initHeight={2} initX={0} initY={0}>
<div>
<h1>Item 1</h1>
</div>
</GridstackItem>
)}
<GridstackItem initWidth={counter} initHeight={4} initX={0} initY={0}>
<button
type="button"
onClick={() => {
setCounter(counter + 1);
}}
>
Item 3 width : {counter}
</button>
</GridstackItem>
</GridstackWrapper>
</>
);
}But I'm having issues when I want to update the grid and for example update the number of column Here is the code, if someone could help me we would finally build a modern react example ! // gridstack-wrapper.tsx
"use client";
import { cn } from "@/utils/cn";
import { GridStack, GridStackNode, GridStackOptions } from "gridstack";
import "gridstack/dist/gridstack.min.css";

const GridContext = createContext<GridStackRefType | undefined>(undefined);
export const useGridstackContext = () => {
const context = useContext(GridContext);
if (context === undefined) {
throw new Error("useGridstackContext must be used within a GridstackWrapper");
}
return context;
};

const gridHTMLElementRef = useRef<HTMLDivElement>(null);
useLayoutEffect(() => {
if (!gridInstanceRef.current && gridHTMLElementRef.current && options) {
initializeGridstack();
} else {
refreshGridstack();
}
// initializeGridstack();
}, [options, setGridstackAPI]);
function initializeGridstack() {
if (!gridInstanceRef.current && gridHTMLElementRef.current && options) {
gridInstanceRef.current = GridStack.init(options, gridHTMLElementRef.current);
toast("GridStack Initialized");
}
}
function refreshGridstack() {
gridInstanceRef.current?.batchUpdate();
gridInstanceRef.current?.commit();
}
// TRYING TO BUILD AN API
useEffect(() => {
if (!gridInstanceRef.current) {
return;
}
const functionSetColumns = (count: number) => {
gridInstanceRef.current?.column(count);
toast(`Column count set to ${count}`);
};
const functionAddWidget = (node: GridStackNode) => {
gridInstanceRef.current?.addWidget(node);
};
setGridstackAPI({
column: functionSetColumns,
addWidget: functionAddWidget,
});
}, [setGridstackAPI, gridInstanceRef]);
return (

<div ref={gridHTMLElementRef} className="grid-stack">

</GridContext.Provider>
);
};
interface GridstackItemProps {

const gridInstanceRef = useGridstackContext();
useLayoutEffect(() => {
const gridInstance = gridInstanceRef.current;
const element = itemRef.current;
if (!gridInstance || !element) {
console.log("Grid instance or itemRef is not ready:", gridInstance, element);
return;
}
console.log("Running batchUpdate and makeWidget");

};

}, []);
return (
<div ref={itemRef} className={cn("grid-stack-item bg-red-100 rounded-lg", className)}>
<div className="grid-stack-item-content">{children}</div>
</div>
);
}; |

yes would be nice to have a working basic example. I'm struggling currently with rendering react node not just text or html |
|
@damien-schneider does the issue still exist? I'm using gridstack in one of my projects and your example could help me a big time. |
|
The issue still exists as I didn't try again, but I will in few weeks. I don't have that much time for now but I will have time very soon |
can I get access to the repo coz I would like to look into the problem in detail? |
|
Hi i've made new version of a gridstack wrapper based on @damien-schneider version it seems to work well so far (i'm new to grid stack) here it is : usage would look like : App.tsx import { GridstackProvider } from './gridstack/gridstack-provider';
import Grid from './grid';
function App() {
return (
<>
<GridstackProvider option={{
column: 12,
animate: true,
float: true,
margin: 0,
acceptWidgets: true,
resizable: {
handles: "all",
},
}}>
<Grid />
</GridstackProvider>
</>
);
}
export default App;grid.tsx import { useContext, useState } from "react";
import { GridStackContext } from "./gridstack/grid-stack-context";
import GridstackWrapper from "./gridstack/gridstask-wrapper";
import { GridstackItem } from "./gridstack/gridstack-item";
const Grid = () => {
const { gridRef } = useContext(GridStackContext)
const [showItem, setShowItem] = useState(false);
const [counter, setCounter] = useState(2);
return (
<>
<button type="button" onClick={() => setShowItem(!showItem)}>
{showItem ? "Hide" : "Show"} item
</button>
<button type="button" onClick={() => gridRef.current?.column(10)}>
Decrease columns
</button>
<button
type="button"
onClick={() => {
gridRef.current?.addWidget({
x: 1,
y: 1,
w: 2,
h: 2,
});
}}
>
Add widget
</button>
<GridstackWrapper>
{showItem && (
<GridstackItem w={2} h={2} x={0} y={0}>
<div>
<h1>Item 1</h1>
</div>
</GridstackItem>
)}
<GridstackItem w={counter} h={4} x={0} y={0}>
<button
type="button"
onClick={() => {
setCounter(counter + 1);
}}
>
Item width : {counter}
</button>
</GridstackItem>
</GridstackWrapper>
</>
)
}
export default Grid; |

I've tried the gist and it works pretty well! Thanks a lot! I think we can little by little create a complete React wrapper, as it is done for Angular (or should we create an external repo ?). I'm playing with it to see what could be the best way to manage features in a controlled way, such as, for example, a controlled way to update the size and position of the item: useLayoutEffect(() => {
const element = itemRef.current;
if (!gridRef.current || !element) {
console.log("Grid instance or itemRef is not ready:", gridRef.current, element);
return;
}
gridRef.current.update(element, {
x: controlledX,
y: controlledY,
w: controlledWidth,
h: controlledHeight,
});
}, [controlledWidth, controlledHeight, controlledX, controlledY, gridRef]);But it has some cons too. Maybe optionally passing an itemRef could be great to easily customize some events. What do you think? (I'm also trying to improve types) |
|
Yes i think it would be easier to collaborate (with PR, etc...) with a repo. Go ahead ! (Or maybe you already have one ?) Btw i've updated my gist with a quite similar solution to update the position/size... But I encounter other issues : because i've also implemented onChange event on the grid and managing the state "outside of the grid", with other triggers that re-render the components tree kinda break everything (Working on it...) What would be your solution with ref? (Ideally I would try to minimize ref usage. I think it's a kind of anti-pattern with react, but i have to admit that sometimes there is no other choices, that why it exists) |
|
Ok let's build this little by little then |
|
let's not create another repo please. I think it's easier to have it all in GS and make it official like I did for Angular (there are already many angular repo flavors which were done incorrectly and got out of sync very quickly, and no longer maintained). I don't know React so really appreciate having community help on this. that said I explicitly wrote the angular version as components (most common usage, the other being directive) AND not using the DOM attributes (for one thing gs doesn't handle all possible values) as gs editing including moving between grids, can be hard to sync with Angular idea of where things should be. I do have simple ngFor dom version but those are naiive implementation and will conflict with gs quickly... I see also mentioned in #2002 (comment) |
|
Agree I think to keep it consistent we should work in this repo. lets just hope PRs will be handled without delays. sometimes in libraries PRs are just hanging years |
|
@sikhaman that's not the case here. if things look good they go in asap. and since I don't know React, likely even faster... |

I've made significant progress in creating a dynamic grid system with Gridstack and React, allowing for state-based updates and management of grid items. However, I'm encountering an issue with the Here's a summary of what I have achieved and the current challenge: Achievements:
Current Challenge:The Additionally, there's a problem with the cleanup process when unmounting a grid item. The following code does not seem to properly remove the widget and the event listener: grid.removeWidget(itemRef.current, false);
grid.off("change");Due to this, remounting the same grid item fails. This prevents the wrapper from fully benefiting from state management.

The Demo:A demo showcases the wrapper's capabilities, demonstrating dynamic state management and grid item control.

not sure what you mean by Also, you are still trying to make framework manage the state - guess you didn't read my comment above. |

By I have read your comment thoroughly, and I appreciate the input. My goal is to help the community use Gridstack with React effectively. The existing React examples are quite outdated compared to current best practices and are often challenging to understand. I’m also curious about how you "inject" Angular components inside your wrapper without using the DOM directly. In my approach, I use the DOM with refs, which allows me to manage Gridstack events without directly manipulating the React DOM, that's why I don't understand why you are always negative with this approach.. Although you mentioned that using state to manage Gridstack might not be advisable, I am confident that it can be achieved. By replicating changes from the grid to the state and vice versa (using
|
https://github.com/gridstack/gridstack.js/blob/master/angular/projects/lib/src/lib/gridstack.component.ts#L229 by not creating items in the DOM directly from the state using ngFor loop, we don't need to sync the states between GS and the app (which can at anytime call save() to get a copy) and widgets can be re-parented betweeen grids without re-creating any components for example.
then you can directly update your state. I appreciate your work on React as I'm not familiar with it, just want to make sure we don't go down the managing 2 states and keeping them in sync when I already went through this for Angular. I made the decision to let GS own the widget state, and the app can serialize the json when needed, else call load() with it. much simpler. And there is many apis to update or add new widgets the app can call directly too... |
Subject of the issue
I'm trying to implement gridstack into my React TypeScript web app and I'm going from the React example. It would be really helpful to have an example written in TypeScript as well, as the types are not always easily deducible and I'm struggling to make everything the correct type to finally successfully compile the app.
Your environment
Steps to reproduce
Expected behavior
Have an example using React with TypeScript to showcase the correct types and stuff.
Actual behavior
Currently only React example with pure JS (without TypeScript and types).
