Skill: Bulk Update Contentful Field
Overview
This skill explains how to use the scripts/bulk-update-field.js script to bulk update a field value for entries in Contentful, including publishing changes. It supports dry-run mode for safe testing.
Prerequisites
- Node.js 18+ (for global fetch)
- Environment variables set (or .env file):
CONTENTFUL_MANAGEMENT_TOKEN (API token)CONTENTFUL_SPACE_ID (space ID)- Optionally:
CONTENTFUL_ENV_ID (defaults to master)
- The script file:
scripts/bulk-update-field.js
Usage
Run the script from the project root:
node scripts/bulk-update-field.js <contentType> <fieldName> <oldValue> <newValue> [--dry]
<contentType>: Contentful content type ID (e.g. ruleReference)<fieldName>: Field to update (e.g. category)<oldValue>: Current value to match (e.g. skill)<newValue>: New value to set (e.g. agent > skill)--dry: Optional. If provided, the script logs actions but does not update or publish entries.
Example
To update all ruleReference entries with category skill to agent > skill:
node scripts/bulk-update-field.js ruleReference category skill "agent > skill"
To simulate the update without making changes:
node scripts/bulk-update-field.js ruleReference category skill "agent > skill" --dry
Features
- Paginates through all matching entries
- Logs each entry and action
- Publishes after update
- Supports dry-run for safe testing
Troubleshooting
- Ensure environment variables are set or .env file exists
- Check field/value spelling and case
- Review logs for errors or skipped entries
When to Use
- Bulk updating field values across many Contentful entries
- Migrating categories, tags, or other metadata
- Testing updates safely with dry-run
For advanced usage or troubleshooting, see the script source or ask for help in the project README.
