Angular Data Grid AG Grid Modules

"dependencies": {
    "ag-grid-community": "~29.3.2" <- a package dependency
    "@ag-grid-enterprise/row-grouping": "~29.3.2"  <- a module dependency
    //...other dependencies...
Installing AG Grid Modules
The grid requires at least one of the following Row Model modules:
ClientSideRowModelModule
InfiniteRowModelModule
ServerSideRowModelModule  
ViewportRowModelModule  
After that all other modules are optional depending on your requirements.
Dependent Modules
As a developer you do not need to worry about module dependencies. For example, the FilterToolPanelModule depends on the
SideBarModule but as we have set up the dependencies as part of the module definition npm will install the dependent packages
for you. Also, when Registering Modules you only need to register the feature you require
and AG Grid will take care of registering any dependant modules.
Registering AG Grid Modules
When including AG Grid in your application via modules it is your responsibility to register the required modules with the grid before it is instantiated. You can either register them globally or pass them individually to each grid instance.
Providing Modules Globally
You can import and register modules to the Grid globally, but you need to ensure that this is done before any Grids are instantiated.
Specify Modules Dependencies
Import Modules
Register Modules
A real-world example might be that we wish to use the Client Side Row Model (the default row model) together with the CSV, Excel and Master/Detail features.
Additionally we're writing an Angular application, so we need to specify the @ag-grid-community/angular dependency:
"dependencies": {
   "@ag-grid-community/client-side-row-model": "~29.3.2",
   "@ag-grid-community/csv-export": "~29.3.2",
   "@ag-grid-enterprise/excel-export": "~29.3.2",
   "@ag-grid-enterprise/master-detail": "~29.3.2",
   "@ag-grid-community/angular": "~29.3.2",
   //...other dependencies...
We now need to register the Grid modules we wish to use - note that this does not include @ag-grid-community/angular as the Angular support is not a Grid feature, but rather a support library:
import { ModuleRegistry } from '@ag-grid-community/core';     // @ag-grid-community/core will always be implicitly available
import { ClientSideRowModelModule } from "@ag-grid-community/client-side-row-model";
import { CsvExportModule } from "@ag-grid-community/csv-export";
import { ExcelExportModule } from "@ag-grid-enterprise/excel-export";
import { MasterDetailModule } from "@ag-grid-enterprise/master-detail";
ModuleRegistry.registerModules([
    ClientSideRowModelModule,
    CsvExportModule,
    ExcelExportModule,
    MasterDetailModule
]);
// you can optionally register individual modules
// ModuleRegistry.register(ClientSideRowModelModule);
// ModuleRegistry.register(CsvExportModule);
// etc
Providing Modules To Individual Grids
The steps required are:
Specify Modules Dependencies
Import Modules
Pass to Grid
Using the same real-world example from above the package.json dependencies will be the same but how we register the modules is different.
Example
import { Component } from '@angular/core';
import { ClientSideRowModelModule } from "@ag-grid-community/client-side-row-model";
import { CsvExportModule } from "@ag-grid-community/csv-export";
import { ExcelExportModule } from "@ag-grid-enterprise/excel-export";
import { MasterDetailModule } from "@ag-grid-enterprise/master-detail"; 
public modules: Module[] = [ClientSideRowModelModule, CsvExportModule, ExcelExportModule, MasterDetailModule];
<ag-grid-angular>
    [rowData]="rowData"
    [columnDefs]="columnDefs" [modules]="modules"</ag-grid-angular>
It's important to note that when a module is added via the modules property, this module will be available to all other instances of the Grid created afterwards. This will produce the same behaviour as registering modules globally by calling ModuleRegistry.registerModules().
This means that you can't limit the functionality of specific grid instances based on whether you've registered a particular module for that specific grid. If a module was already registered by any one AG Grid instance, it is available to all AG Grid instances created subsequently.
To control features per grid use the relevant Grid Property.
Core Modules
If you specify any Community or Enterprise dependency then the corresponding core module will also be pulled in and be made available to you. For example, if you include @ag-grid-community/client-side-row-model - a Community Module - then @ag-grid-community/core will be available. If you include @ag-grid-enterprise/excel-export - an Enterprise Module - then @ag-grid-enterprise/core will also be available.
You'll require the @ag-grid-community/core module for Grid related definitions  and @ag-grid-enterprise/core for the LicenseManager.
If we have the following modules specified:
"dependencies": {
    "@ag-grid-community/client-side-row-model": "~29.3.2",
    "@ag-grid-enterprise/excel-export": "~29.3.2",
    //...other dependencies...
We can then assume the core packages are available implicitly and import from them:
import { ColumnApi, GridApi } from "@ag-grid-community/core";
import { LicenseManager } from "@ag-grid-enterprise/core";
LicenseManager.setLicenseKey(...your key...);
CSS/SCSS Paths
CSS & SCSS is available in the @ag-grid-community/styles module.
/* CSS Community */
import "@ag-grid-community/styles/ag-grid.css";
import "@ag-grid-community/styles/ag-theme-alpine.css";
If using SCSS the theme defaults to alpine, so you don't have to explicitly include it.
// SCSS Community
@use "~@ag-grid-community/styles" as ag;
// Choose balham over default alpine
@include ag.grid-styles((
    theme: balham
));
See Choosing a Theme for full details of how to select a theme.
Module Examples
Our Example Runner enables you to view the modules version of an example via the dropdown in the top right-hand corner.
When 'Modules' is selected, the source code includes the required modules along with the module import paths. This means
you can copy and paste code from our examples without further tweaks.
