SDK packages

Every package,
and where it lives

Twenty-four TypeScript packages, nineteen of them published under the @decentralchain scope and five that live in the monorepo workspace. Knowing which is which saves a confusing half hour: an example written from inside the repository can import a workspace package, and the same line run outside it resolves to nothing.

Nothing on the published list depends on one of these at runtime, so the nineteen stand on their own. Declare your own types where @decentralchain/types would have supplied them.

JVM libraries

Where to start

To read the chain you need nothing at all: the REST API answers a plain fetch. Reach for the packages when you start building transactions, at which point transactions and ts-lib-crypto are the two that matter, and bignumber the moment you handle an amount.
