BotBuilder Community Core

This package should not be used directly in your Bot Framework chatbot. Instead, it is used in other packages to minimize code repetition.

CustomWebAdapter

The CustomWebAdapter adds two extra functions to the default BotAdapter. retrieveBody could be used to retrieve the body of a HTTP request and it will automatically serialize JSON and url-encoded content. delay could be used as a helper function for the delay activity.

It is possible to use the Bot Service OAuth functionality by passing in the optional BotFrameworkAdapterSettings object. If you want to implement your own OAuth functionality in YourOwnAdapter, you could override the existing OAuth functions found in IUserTokenProvider. Sample code for adding OAuth to your bot can be found here.

import { CustomWebAdapter } from '@botbuildercommunity/core';

export class YourOwnAdapter extends CustomWebAdapter {

    protected readonly yourOwnAdapterSettings: YourOwnAdapterSettings;

    public constructor(yourOwnAdapterSettings: YourOwnAdapterSettings, botFrameworkAdapterSettings?: BotFrameworkAdapterSettings) {
        // Add optional botFrameworkAdapterSettings to enable OAuth on custom adapters
        super(botFrameworkAdapterSettings);
    }

    public async processActivity(req: WebRequest, res: WebResponse, logic: (context: TurnContext) => Promise<any>): Promise<void> {
        const body = this.retrieveBody(req);
        ...
    }

    public async sendActivities(context: TurnContext, activities: Partial<Activity>[]): Promise<ResourceResponse[]> {
        const responses: ResourceResponse[] = [];

        for (let i = 0; i < activities.length; i++) {
            const activity: Partial<Activity> = activities[i];

            switch (activity.type) {
                case 'delay':
                    await delay(activity.value);
                    responses.push({} as ResourceResponse);
                    break;
                    ...
            }
        }
    }
}
