Running tsgo (TS 7) alongside tsc (TS 5) in a pnpm Monorepo

A practical guide to using TypeScript's native Go-based compiler for local development while keeping the traditional tsc as your CI source of truth.

Why both?

TypeScript 7.0 is a ground-up port of the compiler to Go. It reads the same tsconfig.json and produces structurally identical type-checking results — just ~10x faster thanks to native code and shared-memory parallelism.

The catch: it's still in dev preview. Ecosystem tooling (editors, build plugins, lint integrations) still depends on the JS-based typescript package. So you run both:

require 'net/http'
require 'uri'
require 'json'

def put_metric(name, value, unit='Count')
  metric_name = "ApiSidekiq#{name.split('_').collect(&:capitalize).join}"
  `/usr/local/bin/aws cloudwatch put-metric-data --metric-name #{metric_name} --namespace Sidekiq --value #{value} --unit #{unit}`
end

uri = URI.parse("#{ENV['SIDEKIQ_WEB_HOST']}/stats")
