UNDERSTAND WHAT YOU RUN
Modules, setup & testing.
Type-check before execution
Use an approved project with TypeScript 5.x and @types/node installed, and package.json set to "type": "module". Azure SDK examples also require the packages named in their requirements. Compile into a separate folder. These scripts use Node.js APIs and are not browser snippets.
tsc --strict --target ES2022 --module nodenext --moduleResolution nodenext --outDir dist script.ts
# Only after successful checks and review:
node dist/script.js
Modules and types
TypeScript adds compile-time checks; it does not validate JSON or external input at runtime. Use explicit guards on unknown values. The library examples demonstrate both types and runtime checks.
const value: unknown = JSON.parse(input);
if (typeof value !== "object" || value === null) {
  throw new Error("Expected an object");
}
Review compiler configuration
Use a project-local compiler, strict checks and a reviewed dependency lockfile. A syntax transformation is not the same as a full type-check. Build instructions here assume Node.js type definitions are available.
tsc --version
tsc --noEmit --strict --target ES2022 --module nodenext --moduleResolution nodenext script.ts
Keep changes intentional
Tailor parameters, read every file path and inspect the output on sample data. Nothing in this page is executed against your devices. Export runbooks to retain edited copies.
// Prefer unknown over any for untrusted input.
// Runtime validation still matters after a clean build.
YOUR LOCAL WORKSPACE

    Validate a JSON service definition using explicit runtime checks, not a type assertion.
    Runtime type guards · TypeScript 5.x / Node.js 22+

    Report flags that are not explicitly boolean; does not rewrite the configuration.
    Record type validation · TypeScript 5.x / Node.js 22+
  • Compare required configuration keys without showing values
    Input {"baseline":{"PORT":80},"actual":{}}. Compares top-level keys and JavaScript types; never prints values. Does not validate nested configuration.

    Validate timezone-qualified dates and check whether the current time lies in the window.
    Date validation · TypeScript 5.x / Node.js 22+
  • Flag stale backup inventory entries
    Validate an exported backup inventory and flag records older than 24 hours. Does not establish restorability.

  • Calculate restoration time for closed incidents
    Input [{"started":"2026-01-01T00:00:00Z","restored":"2026-01-01T00:30:00Z"}]. Calendar elapsed time, not business hours or SLA compliance.
    Node.js built-ins · TypeScript 5.9+, Node.js 22+
  • Find active tickets without a responsible owner
    Input [{"id":"INC1","status":"open","owner":null}]. Closed and resolved statuses are excluded; adapt these labels to your ticket system. No ticket contents printed.
    Node.js built-ins · TypeScript 5.9+, Node.js 22+
  • Flag open tickets exceeding an age threshold
    Validate a JSON ticket export and identify open tickets older than the configured hours. This measures elapsed time, not business-hours SLA compliance.

Change management · 1 tasks
  • Detect overlapping approved change windows
    Input [{"id":"CHG1","start":"2026-01-01T00:00:00Z","end":"2026-01-01T01:00:00Z"}]. Half-open intervals; touching windows do not collide. Does not infer affected services.

Web support · 2 tasks
  • Review captured HTTP security headers offline
    Input a JSON object of response headers captured separately. Offline presence checks only; not a security certification. HSTS is relevant to HTTPS.

Logs · 1 tasks
  • Find gaps in an exported event sequence
    Input [100,101,104]. Detect missing ranges and repeated sequence numbers without generating every missing value. Only meaningful for one ordered event stream; resets must be split first.

Validate data at runtime
Treat imported JSON as unknown and check its shape before use. A type assertion changes the compiler view; it does not validate outside data.
