JavaScript and TypeScript

The JavaScript and TypeScript SDK supports current Node.js LTS releases. This example uses an ES module; the same SDK calls work in TypeScript.

Install the SDK

npm install context.dev

Set your API key

Get a secret API key from the dashboard. Set it in the terminal where you will run the example:

export CONTEXT_DEV_API_KEY="ctxt_secret_..."

Keep the key in server-side code. Do not expose it in a browser or commit it to source control.

Scrape a webpage

Save this as scrape.mjs:

scrape.mjs

import ContextDev from "context.dev";

const client = new ContextDev({
  apiKey: process.env.CONTEXT_DEV_API_KEY,
});

const response = await client.web.webScrapeMd({
  url: "https://example.com",
  useMainContentOnly: true,
});

console.log(response.markdown);

Run it from the same directory:

node scrape.mjs

Run the example in TypeScript

Save the same example as scrape.mts. Install tsx as a development dependency, then run it:

npm install --save-dev tsx
npx tsx scrape.mts

Check the result

The example prints the page content as Markdown. Look for the Example Domain heading; the remaining text and formatting may vary.

Expected heading

# Example Domain

If you receive an error, check the key and request details in Troubleshooting. See the Markdown API reference for all parameters and response fields.

Retrieve brand data

Replace the request and final console.log with this lookup. It prints the matched company name.

const response = await client.brand.retrieve({
  type: "by_domain",
  domain: "stripe.com",
});

console.log(response.brand.title);
