Exa Upgrade & Migration

Current State

!npm list exa-js 2>/dev/null | grep exa-js || echo 'exa-js not installed' !npm view exa-js version 2>/dev/null || echo 'cannot check latest'

Overview

Guide for upgrading the exa-js SDK. The SDK import is import Exa from "exa-js" and the client is instantiated with new Exa(apiKey). This skill covers checking for updates, handling breaking changes, and validating after upgrade.

Instructions

Step 1: Check Current vs Latest Version

set -euo pipefail
echo "Current version:"
npm list exa-js 2>/dev/null || echo "Not installed"

echo ""
echo "Latest available:"
npm view exa-js version

echo ""
echo "Changelog:"
npm view exa-js repository.url

Step 2: Create Upgrade Branch

set -euo pipefail
git checkout -b upgrade/exa-js-latest
npm install exa-js@latest
npm test

Step 3: Verify API Compatibility

import Exa from "exa-js";

async function verifyUpgrade() {
  const exa = new Exa(process.env.EXA_API_KEY);
  const checks = [];

  // Check 1: Basic search
  try {
    const r = await exa.search("upgrade test", { numResults: 1 });
    checks.push({ method: "search", status: "OK", results: r.results.length });
  } catch (err: any) {
    checks.push({ method: "search", status: "FAIL", error: err.message });
  }

  // Check 2: searchAndContents
  try {
    const r = await exa.searchAndContents("upgrade test", {
      numResults: 1,
      text: { maxCharacters: 100 },
      highlights: { maxCharacters: 100 },
    });
    checks.push({
      method: "searchAndContents",
      status: "OK",
      hasText: !!r.results[0]?.text,
      hasHighlights: !!r.results[0]?.highlights,
    });
  } catch (err: any) {
    checks.push({ method: "searchAndContents", status: "FAIL", error: err.message });
  }

  // Check 3: findSimilar
  try {
    const r = await exa.findSimilar("https://nodejs.org", { numResults: 1 });
    checks.push({ method: "findSimilar", status: "OK", results: r.results.length });
  } catch (err: any) {
    checks.push({ method: "findSimilar", status: "FAIL", error: err.message });
  }

  // Check 4: getContents
  try {
    const r = await exa.getContents(["https://nodejs.org"], { text: true });
    checks.push({ method: "getContents", status: "OK", hasContent: !!r.results[0]?.text });
  } catch (err: any) {
    checks.push({ method: "getContents", status: "FAIL", error: err.message });
  }

  console.table(checks);
  const allPassed = checks.every(c => c.status === "OK");
  console.log(`\nUpgrade verification: ${allPassed ? "PASSED" : "FAILED"}`);
  return allPassed;
}

Step 4: Common Breaking Change Patterns

// Import style (has been stable)
import Exa from "exa-js";  // default export

// Constructor (has been stable)
const exa = new Exa("api-key");

// If upgrading from a very old version, check:
// - Method names: searchAndContents (not searchWithContents)
// - findSimilarAndContents (not findSimilarWithContents)
// - Parameter names: numResults (not num_results)
// - Content options: text, highlights, summary as objects

// Check for deprecated parameters
// - livecrawl may be replaced by maxAgeHours in newer versions
// - Check changelog for parameter renames

Step 5: Rollback Procedure

set -euo pipefail
# If tests fail, rollback
npm install exa-js@<previous-version> --save-exact
git checkout -- package-lock.json  # restore lockfile
npm test  # verify rollback works

Upgrade Checklist

Create branch: upgrade/exa-js-latest
Run npm install exa-js@latest
Run full test suite: npm test
Run upgrade verification script (checks all methods)
Check for deprecation warnings in output
Review changelog for breaking changes
Update any changed parameter names
Merge after all checks pass

Error Handling

Issue	Cause	Solution
Import error after upgrade	API change	Check `import Exa from "exa-js"` still works
Method not found	Renamed method	Check SDK changelog
Type errors	Parameter type changes	Update TypeScript types
Tests fail	Breaking change	Review changelog, update code
