valSession
HTTP
Val Session import { ValSession } from "https://esm.town/v/maxm/valSession";
// Generate a token from your valtown api key.
const token = await ValSession.newSession(Deno.env.get("valtown"));
// Other services can use it to authenticate
const user = await ValSession.validate(token); Fork it, provide your own VT_SESSION_PRIVATE_KEY, and update the hardcoded public key. You can generate your own keys like so: import { crypto } from "https://deno.land/std@0.198.0/crypto/mod.ts";
// Generate a key pair for JWT signing and verification
const { privateKey, publicKey } = await crypto.subtle.generateKey(
{
name: "RSASSA-PKCS1-v1_5",
modulusLength: 2048,
publicExponent: new Uint8Array([1, 0, 1]),
hash: "SHA-256",
}, true, ["sign", "verify"],
);
function formatPEM(b64: string, type: "PRIVATE KEY" | "PUBLIC KEY"): string {
const lines = b64.match(/.{1,64}/g) || [];
return `-----BEGIN ${type}-----\n${lines.join("\n")}\n-----END ${type}-----`;
}
const privateKeyPem = formatPEM(
btoa(String.fromCharCode(...new Uint8Array(exportPrivateKey))),
"PRIVATE KEY",
);
const publicKeyPem = formatPEM(
btoa(String.fromCharCode(...new Uint8Array(exportPublicKey))),
"PUBLIC KEY",
);
console.log(privateKeyPem, publicKeyPem);

textSummarizationComparisonTool
HTTP
* This val creates a text summarization comparison tool using the Cerebras LLM API.
* It provides a text area with default text, a summarize button, and displays two different summarization results:
* 1. Direct summarization
* 2. Extractive summarization followed by cohesive rewriting
*
* The server handles API calls to Cerebras, while the client manages the UI and user interactions.
