Feature request

Integrate a Google Jobs query tool in LangChainJS to enable users to search and retrieve job listings directly through Google Jobs, aligning with the functionality available in LangChain's Python library. This tool will allow JavaScript developers to seamlessly add job search capabilities within their LangChainJS applications.

Motivation

Currently, the LangChain Python library has robust integration for similar search capabilities, but the JS version lacks Google Jobs support. This addition would enrich the ecosystem by enabling JavaScript developers to access job search results directly within LangChain, without relying on external libraries or tools.

Proposal (If applicable)

We are a team of three students from the University of Toronto, aiming to develop this feature and submit a pull request by mid-November.This integration seeks to expand LangChain’s capability to handle a wider range of job related queries.

Implementation Outline
We will implement Google Jobs integration by creating a GoogleJobsTool within the tools directory, leveraging SerpApi to handle job search requests. This tool will use SerpApi’s capabilities to help with job related queries.

class GoogleJobsQuery {
  constructor(query, location = "") {
    this.query = query;
    this.location = location;
    this.apiKey = process.env.SERPAPI_API_KEY;
  }

  async run() {
    if (!this.apiKey) {
      throw new Error("API key is missing");
    }

    const params = new URLSearchParams({
      engine: "google_jobs",
      q: this.query,
      location: this.location,
      api_key: this.apiKey,
    });

    const response = await fetch(`https://serpapi.com/search?${params.toString()}`);
    const data = await response.json();

    return data.jobs_results.map(job => ({
      title: job.title,
      company: job.company_name,
      location: job.location,
      description: job.description,
      link: job.link,
    }));
  }
}

Example Usage

try {
  const jobQuery = new GoogleJobsQuery("Software Engineer", "Toronto");
  const results = await jobQuery.run();

  console.log("Job Listings:", results);
} catch (error) {
  console.error("Error querying Google Jobs:", error);
}

Hey @bracesproul @jacoblee93, We're a team of three UofT students, and we've started working on the code for this feature. We're wondering if this could be considered as a potential issue to explore. Would love to hear your thoughts on it! Thank you!

Hi @jacoblee93! When you have a moment, I’d love to get your thoughts on this proposal. We’re aiming to submit a PR by the end of next week. Thanks so much!
