Updating Lexicons#

When Tangled.org updates their lexicon schemas, run the update script:

npm run update-lexicons

This script:

1. Downloads the latest lexicon files from tangled.org over HTTPS
2. Saves them to the lexicons/ directory
3. Preserves the directory structure

After updating lexicons:

1. Update the "Last Updated" date in this README
2. Regenerate client code: npm run codegen
3. Run tests to ensure compatibility: npm test
4. Commit both lexicon updates and generated code changes

Manual Update (if script fails):

• Lexicons can be manually downloaded from: https://tangled.org/tangled.org/core/raw/master/lexicons/<path>
• Example: https://tangled.org/tangled.org/core/raw/master/lexicons/issue/issue.json

Code Generation#

Client TypeScript code is generated from these lexicons using @atproto/lex-cli:

npm run codegen

This generates type-safe client code in src/lexicon/ which is committed to version control.
