Remove `ExtensionFileSourceCode::LoadedFromFsDuringSnapshot` and feature `include_js_for_snapshotting` since they leak paths that are only applicable in this repo to embedders. Replace with feature `exclude_js_sources`. Additionally the feature `force_include_js_sources` allows negating it, if both features are set. We need both of these because features are additive and there must be a way of force including sources for snapshot creation while still having the `exclude_js_sources` feature. `force_include_js_sources` is only set for build deps, so sources are still excluded from the final binary. You can also specify `force_include_js_sources` on any extension to override the above features for that extension. Towards #19398. But there was still the snapshot-from-snapshot situation where code could be executed twice, I addressed that by making `mod_evaluate()` and scripts like `core/01_core.js` behave idempotently. This allowed unifying `ext::init_ops()` and `ext::init_ops_and_esm()` into `ext::init()`. |

deno_runtime
crate
This is a slim version of the Deno CLI which removes typescript integration and various tooling (like lint and doc). Basically only JavaScript execution with Deno's operating system bindings (ops).
Stability
This crate is built using battle-tested modules that were originally in deno
crate, however the API of this crate is subject to rapid and breaking changes.
MainWorker
The main API of this crate is MainWorker
. MainWorker
is a structure
encapsulating deno_core::JsRuntime
with a set of ops used to implement Deno
namespace.
When creating a MainWorker
implementors must call MainWorker::bootstrap
to
prepare JS runtime for use.
MainWorker
is highly configurable and allows to customize many of the
runtime's properties:
- module loading implementation
- error formatting
- support for source maps
- support for V8 inspector and Chrome Devtools debugger
- HTTP client user agent, CA certificate
- random number generator seed
Worker
Web API
deno_runtime
comes with support for Worker
Web API. The Worker
API is
implemented using WebWorker
structure.
When creating a new instance of MainWorker
implementors must provide a
callback function that is used when creating a new instance of Worker
.
All WebWorker
instances are descendents of MainWorker
which is responsible
for setting up communication with child worker. Each WebWorker
spawns a new OS
thread that is dedicated solely to that worker.
