@micsob/bring-api-client

A zero-dependency, functional TypeScript client for Bring! shopping lists.

This project uses an undocumented API and is not endorsed by or affiliated with Bring! Labs AG.

Requirements

• Node.js 22 or newer
• An existing Bring! account for authenticated endpoints

Installation

npm install @micsob/bring-api-client

Usage

connectBring authenticates and returns a client that is ready to use. There is no constructor and no separate login() step.

import { connectBring } from '@micsob/bring-api-client';

const bring = await connectBring({
    email: 'example@example.com',
    password: 'secret'
});

const { lists } = await bring.lists.getAll();
const items = await bring.lists.getItems({ listId: lists[0].listUuid });

Reuse an existing session

Pass a stored session to avoid logging in again:

import { createBringClient } from '@micsob/bring-api-client';

const bring = createBringClient({
    session: {
        userId: process.env.BRING_USER_ID,
        accessToken: process.env.BRING_ACCESS_TOKEN,
        refreshToken: process.env.BRING_REFRESH_TOKEN
    }
});

const { lists } = await bring.lists.getAll();

Use bring.getSession() after connectBring() if the application needs to persist the returned tokens. Do not commit credentials or tokens to source control.

Public resources

Catalogs and translations do not require authentication or a client:

import { getCatalog, getTranslations } from '@micsob/bring-api-client';

const catalog = await getCatalog({ locale: 'de-DE' });
const translations = await getTranslations({ locale: 'de-DE' });

Change a shopping list

await bring.lists.saveItem({
    listId: '9b3ba561-02ad-4744-a737-c43b7e5b93ec',
    name: 'Coffee',
    specification: 'Whole beans'
});

await bring.lists.moveItemToRecent({
    listId: '9b3ba561-02ad-4744-a737-c43b7e5b93ec',
    name: 'Coffee'
});

All operations accept an optional second argument with an AbortSignal:

const items = await bring.lists.getItems(
    { listId: '9b3ba561-02ad-4744-a737-c43b7e5b93ec' },
    { signal: AbortSignal.timeout(5_000) }
);

Errors

Failed HTTP responses and network failures reject with a structured BringApiError:

import { isBringApiError } from '@micsob/bring-api-client';

try {
    await bring.lists.getAll();
} catch (error) {
    if (isBringApiError(error)) {
        console.error(error.status, error.code, error.message);
    }
}

API overview

• connectBring(credentials, options?)
• authenticate(credentials, options?)
• createBringClient({ session, ...options })
• bring.lists: getAll, getItems, getItemDetails, saveItem, removeItem, moveItemToRecent, getUsers
• bring.itemImages: save, remove
• bring.user.getSettings
• bring.invitations.getPending
• getCatalog(options)
• getTranslations(options)

The optional client configuration supports baseUrl, a custom fetch implementation, API headers and country selection. All public TypeScript types are exported from the package root.

Migrating from v2

Version 3 is ESM-only and replaces the stateful Bring class:

- const Bring = require('bring-shopping');
- const bring = new Bring({ mail, password });
- await bring.login();
- const lists = await bring.loadLists();
+ import { connectBring } from '@micsob/bring-api-client';
+ const bring = await connectBring({ email: mail, password });
+ const lists = await bring.lists.getAll();

Mutating methods now return Promise<void> and reject for non-successful HTTP statuses. Method arguments use named objects and uuid arguments are named listId or itemId.

Development

The project uses TypeScript 7, Oxlint with type-aware rules and Oxfmt:

npm ci
npm run check

Use npm run format to apply the repository formatting rules.
