📄️ Extending LangChain.js
Extending LangChain's base abstractions, whether you're planning to contribute back to the open-source repo or build a bespoke internal integration, is encouraged.
📄️ Fallbacks
When working with language models, you may often encounter issues from the underlying APIs, e.g. rate limits or downtime.

📄️ Migrating to 0.1
If you're still using the pre 0.1 version of LangChain, but want to upgrade to the latest version, we've created a script that can handle almost every aspect of the migration for you.
