Where is the SequentialChain exported from ?

[vpaul18]

Hi !

I'm trying to convert the python implementation of Langchain to JS, yet I cannot seem to find where the SequentialChain is exported from in this repo. Or is it not supported yet?

Thanks!

This was just merged today #834 will release in a few hours

Edit: actually a similar chain (but not this exact one) was merged today, see below for context

@nfcampos I'm not sure whether this issue refers exactly to the PR. The Python implementation has two distinct classes, SimpleSequentialChain and SequentialChain. I only implemented the SimpleSequentialChain in the mentioned PR. If necessary I could also start implementing SequentialChain as I already have some insight into this area of the project.

Ah yes quite right @kwkr my mistake. If you want to contribute that it would be great, but no pressure

[kwkr]

Yeah, I would be happy to help. How should I proceed with this? Do I just start working on it or should some issue first be created or this one could be used?

[nfcampos]

Yea just start, we can use this issue, I've reopened it

Hi, @vpaul18! I'm helping the LangChain team manage their backlog and I wanted to let you know that we are marking this issue as stale.

From what I understand, you were asking about the export location of SequentialChain in the repository as you were trying to convert the Python implementation of Langchain to JS. It was mentioned that a similar chain was merged recently, but not this exact one. Another user, kwkr, offered to start implementing SequentialChain and the issue was reopened for this purpose. It seems like there has been some progress and potential resolution to this issue.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself or it will be automatically closed in 7 days.

Thank you for your understanding and contribution to the LangChain project!
