Bring! Add Items CLI

Overview

CLI for adding items to Bring! shopping lists. Supports quick single-item mode, batch mode, stdin/pipe input, and interactive mode.

When to Use

Use this skill when:

• User wants to add items to a Bring! shopping list
• Adding single item with optional specification (e.g., "Milk 1L")
• Adding multiple items at once (batch mode)
• Piping items from a file or other command
• Need to preview additions with dry-run
• Need JSON output for scripting

Don't use when:

• User wants to browse recipes (use bring-recipes instead)
• User wants to remove items from a list
• User wants to view current list contents

Installation

cd skills/bring-add
npm install

Common Workflows

Add a single item:

node index.js "Tomatoes" "500g"
node index.js "Milk"

Add to specific list:

node index.js --list "Party" "Chips" "3 bags"

Batch add multiple items:

node index.js --batch "Tomatoes 500g, Onions, Cheese 200g"

Pipe from file:

cat shopping-list.txt | node index.js -
echo -e "Milk 1L\nBread\nButter" | node index.js -

Preview before adding:

node index.js --dry-run --batch "Apples 1kg, Pears"

Get JSON output:

node index.js --json --batch "Milk, Bread" 2>/dev/null

List available lists:

node index.js lists
node index.js --json lists

Flags Reference

Flag	Description
-l, --list <name>	Target list (name or UUID)
-b, --batch <items>	Comma-separated items
-n, --dry-run	Preview without modifying
-q, --quiet	Suppress non-error output
-v, --verbose	Show detailed progress
--json	Output JSON to stdout
--no-color	Disable colored output
--no-input	Never prompt; fail if input required

Input Format

Items follow the pattern: ItemName [Specification]

Input	Item	Spec
Tomatoes 500g	Tomatoes	500g
Oat milk 1L	Oat milk	1L
Red onions 3	Red onions	3
Cheese	Cheese	(empty)

Rule: Last word becomes specification if it contains a number or unit (g, kg, L, ml, Stück, pck).

Exit Codes

Code	Meaning
0	Success
1	Generic failure (API error, network)
2	Invalid usage (bad args, missing input)
3	Authentication failed
4	List not found
130	Interrupted (Ctrl-C)

Common Mistakes

Forgetting environment variables: Set BRING_EMAIL and BRING_PASSWORD before running.

Wrong list name: Use bring-add lists to see available lists and their exact names.

Specification parsing: The last word is treated as specification only if it looks like a quantity. "Red onions" stays as one item, but "Red onions 3" splits into item "Red onions" with spec "3".

Interactive mode in scripts: Use --no-input flag in scripts to fail explicitly rather than hang waiting for input.

Implementation Notes

• Uses node-bring-api with batchUpdateList() API
• Requires Node.js 18.0.0+
• Outputs data to stdout, progress/errors to stderr
• JSON mode available for automation
• Interactive mode only when stdin is a TTY
