JsRuntime
in package
The JsRuntime is a wrapper around a V8 isolate. It can execute ES6 including ES6 modules. The JsRuntime does not include any of the Deno.core.* ops, and does not provide implementations for web apis, such as fetch(). Use JsRuntime if you want to provide low-level v8 isolates, and implement extensions for all functionality such as local storage, remote requests etc.

Methods
__construct()
public
__construct(RuntimeOptions $options) : mixed
Parameters
- $options : RuntimeOptions
execute_script()
Execute JavaSscript inside the V8 Isolate.
public
execute_script(string $name, string $source_code) : mixed
This does not support top level await for Es6 imports. use load_main_module
to execute JavaScript in modules.
Parameters
- $name : string
- $source_code : string
load_main_module()
Load an ES6 module as the main starting module.
public
load_main_module(string $specifier, string|null $code) : int
This function returns a module ID which should be passed to mod_evaluate().
Parameters
- $specifier : string
- $code : string|null
Return values
intmod_evaluate()
Evaluate a given module ID. This will run all schyonous code in the module.
public
mod_evaluate(int $id) : mixed
If there are pending Promises or async axtions, use run_event_loop() to
wait until all async actions complete.
Parameters
- $id : int
run_event_loop()
Wait for the event loop to run all pending async actions.
public
run_event_loop() : mixed
snapshot()
Takes a snapshot. The isolate should have been created with will_snapshot set to true.
