Host.historyReplace
luastra/hostHost.historyReplace(stateToken: string): RequestId
Replaces the current browser-history state token without adding a new Back entry. It keeps the current location and returns a RequestId for host acknowledgement.
Before you use it
Add luastra/host to this module's dependencies in luastra.json, then import it with require("luastra/host"). Declare navigation.history in luastra.json. Save the returned RequestId with its purpose and implement app.resolve.
How it fits
The function starts an asynchronous host request and returns immediately. app.resolve receives its success payload or stable failure code; availability and permission can vary by host.
When to use it
Use Host.historyReplace when correcting or initializing the current entry so Back should not revisit the previous state. Use push for a user-visible navigation step.
Parameters
| Parameter | Type / values | Description |
|---|---|---|
| stateToken | string | Opaque encoded state replacing the current history entry. |
Returns
RequestId — an opaque request identifier used to correlate the asynchronous completion in app.resolve.
What happens next
A RequestId now, followed later by one matching app.resolve completion.
Failures and fixes
Undeclared capability, unavailable host support, denied permission, invalid input, deadline, network, or internal failure reaches the bounded failure path. Public completion codes are CANCELLED, DEADLINE, FORBIDDEN, INTERNAL, NETWORK, UNAUTHORIZED, and VALIDATION.
Availability
Public-source alpha capability API in 0.5.0-alpha; verify each claimed host independently.
Focused example
local Host = require("luastra/host")
Host.historyReplace(router.encode())
