This commit adds proper support for import assertions and JSON modules. Implementation of "core/modules.rs" was changed to account for multiple possible module types, instead of always assuming that the code is an "ES module". In effect "ModuleMap" now has knowledge about each modules' type (stored via "ModuleType" enum). Module loading pipeline now stores information about expected module type for each request and validates that expected type matches discovered module type based on file's "MediaType". Relevant tests were added to "core/modules.rs" and integration tests, additionally multiple WPT tests were enabled. There are still some rough edges in the implementation and not all WPT were enabled, due to: a) unclear BOM handling in source code by "FileFetcher" b) design limitation of Deno's "FileFetcher" that doesn't download the same module multiple times in a single run Co-authored-by: Kitson Kelly <me@kitsonkelly.com> |

Tools
Documentation for various tooling in support of Deno development.
format.js
This script will format the code (currently using dprint, rustfmt). It is a prerequisite to run this before code check in.
To run formatting:
deno run --allow-read --allow-write --allow-run --unstable ./tools/format.js
lint.js
This script will lint the code base (currently using dlint, clippy). It is a prerequisite to run this before code check in.
To run linting:
deno run --allow-read --allow-write --allow-run --unstable ./tools/lint.js
Tip: You can also use cargo to run the current or pending build of the deno executable
cargo run -- run --allow-read --allow-write --allow-run --unstable ./tools/<script>
flamebench.js
flamebench.js
facilitates profiling and generating flamegraphs from
benchmarks.
General usage:
❯ ./tools/flamebench.js
flamebench <bench_name> [bench_filter]
Available benches:
op_baseline
ser
de
To profile the op_baseline
bench, run ./tools/flamebench.js op_baseline
,
this will run all 3 benches in `op_baseline.
Often when profiling/optimizing, you'll want to focus on a specific sub-bench,
flamebench
supports a bench/test filter arg like the regular cargo commands.
So you can simply run ./tools/flamebench.js op_baseline bench_op_async
or
./tools/flamebench.js op_baseline bench_op_nop
to profile specific benches.
Tip: the [bench_filter]
argument doesn't have to be an exact bench name, you
can use a shorthand or a partial match to profile a group of benches, e.g:
./tools/flamebench.js de v8
