 Looking for tutorials to get started? Look at [examples](https://polkadot.js.org/docs/api/examples/promise/) for guides on how to use the API to make queries and submit transactions.

-## overview
-
-The API is split up into a number of internal packages -
-
-- [@polkadot/api](packages/api/) The API library, providing both Promise and RxJS Observable-based interfaces. This is the main user-facing entry point.
-- [@polkadot/api-derive](packages/api-derive/) Derived results that are injected into the API, allowing for combinations of various query results (only used internally and exposed on the Api instances via `api.derive.*`)
-- [@polkadot/metadata](packages/metadata/) Base extrinsic, storage and constant injectors for injection
-- [@polkadot/rpc-core](packages/rpc-core/) Wrapper around all [JSON-RPC methods](https://polkadot.js.org/docs/substrate/rpc) exposed by a Polkadot network client
-- [@polkadot/rpc-provider](packages/rpc-provider/) Providers for connecting to nodes, including WebSockets and Http
-
-Type definitions for interfaces as exposed by Polkadot & Substrate clients -

-- [@polkadot/types](packages/types/) Codecs for all Polkadot and Substrate primitives

+ * Creates a new health checker.
+ *
+ * The role of the health checker is to report to the user the health of a smoldot chain.
+ *
+ * In order to use it, start by creating a health checker, and call `setSendJsonRpc` to set the
+ * way to send a JSON-RPC request to a chain. The health checker is disabled by default. Use
+ * `start()` in order to start the health checks. The `start()` function must be passed a callback called
+ * when an update to the health of the node is available.
+ *
+ * In order to send a JSON-RPC request to the chain, you **must** use the `sendJsonRpc` function
+ * of the health checker. The health checker rewrites the `id` of the requests it receives.
+ *
+ * When the chain send a JSON-RPC response, it must be passed to `responsePassThrough()`. This
+ * function intercepts the responses destined to the requests that have been emitted by the health
+ * checker and returns `null`. If the response doesn't concern the health checker, the response is
+ * simply returned by the function.
+ *
+ * # How it works
+ *
+ * The health checker periodically calls the `system_health` JSON-RPC call in order to determine
+ * the health of the chain.
+ *
+ * In addition to this, as long as the health check reports that `isSyncing` is `true`, the
+ * health checker also maintains a subscription to new best blocks using `chain_subscribeNewHeads`.
+ * Whenever a new block is notified, a health check is performed immediately in order to determine
+ * whether `isSyncing` has changed to `false`.
+ *
+ * Thanks to this subscription, the latency of the report of the switch from `isSyncing: true` to
+ * `isSyncing: false` is very low.
