jira.jsJira REST API client

Type-safe client for the Jira Cloud platform, Agile and Service Management APIs — Node.js and browsers, ESM, every response validated.

🧩

Full Cloud coverage

The Jira Cloud platform API, Agile (boards, sprints, backlog) and Jira Service Management — nearly every endpoint, one client.

🔒

TypeScript-first

Every endpoint, parameter and model is typed, and the published package ships its sources so "go to definition" lands on the real thing.

🛡️

Validated at runtime

Responses are checked against a schema. Drift is reported by field, once, without taking your integration down.

🌳

Tree-shakable

Import the flat function you need instead of a whole client, and leave the rest out of the bundle.

🔑

OAuth 2.0 built in

Email + API token, bearer tokens, or 3LO with automatic refresh, single-flight, 401 retry and cloud id resolution.

🌍

Node.js and browsers

One ESM build that runs in Node.js 22+ and in the browser, on one runtime dependency.
