How can I use ag-grid table within django template

Suppose you want to render a simple data, which is a list of dictionaries. Each dictionary can be thought of as a data object with consistent keys.
Pay attention to how the code accesses column names from the first object in the list using Object.keys(<js object>) method. This way you can reuse this template for multiple django views. All you need is you are passing data that is a list of dictionaries with consistent keys.

    // Django JSON Data (Rendered from View)
    var rowData = {{ data | safe }};

    console.log(`data is ${JSON.stringify(rowData)}`)


    const columnDefs = Object.keys(rowData[0]).map((columnName)=>({headerName:columnName, field:columnName, filter: "agTextColumnFilter"}))
    // Grid Options
    var gridOptions = {
        columnDefs: columnDefs,
        rowData: rowData,
        pagination: true
    };

    // Initialize ag-Grid
    document.addEventListener('DOMContentLoaded', function () {
        var gridDiv = document.querySelector("#myGrid");
        //new agGrid.Grid(gridDiv, gridOptions);
        const gridApi = agGrid.createGrid(gridDiv, gridOptions);
    });
