ts-libs: tested TypeScript building blocks for web-standards back ends

Eight framework-agnostic packages built on web standards: ES modules, Fetch, Web Crypto and Streams. Sign-in, Postgres access, SMTP, safe outbound requests, time zones and validation, each with a one-line install. Every package is tested on Deno, the runtime I build with.

Live proof

My SaaS template imports @spy4x/validation, @spy4x/platform and @spy4x/server, and this site encrypts its environment files with @spy4x/server's age64 module. More of the site is moving over to these packages now.

Install

deno add jsr:@spy4x/[email protected]

From JSR, pinned to 1.3.0.

8 packages, each installed on its own:

@spy4x/email
@spy4x/integrations
@spy4x/net
@spy4x/platform
@spy4x/realtime
@spy4x/server
@spy4x/time
@spy4x/validation

Use it if

You build TypeScript services on web standards and want sign-in, Postgres access, SMTP or SSRF-safe outbound requests without writing them again.
You validate data with arktype and want one result shape for it.
You want small packages you install one at a time, not a framework.

Don't use it if

You validate with zod and want to keep it: these packages use arktype only.
You need a package tested on Node or Bun: every package is tested on Deno only.
You want an app framework: there are no app shells and no UI here.
