From d47147fb6ad229b1c039aff9d0959b6e281f4df5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bartek=20Iwa=C5=84czuk?= Date: Tue, 14 Feb 2023 17:38:45 +0100 Subject: feat(ext/node): embed std/node into the snapshot (#17724) This commit moves "deno_std/node" in "ext/node" crate. The code is transpiled and snapshotted during the build process. During the first pass a minimal amount of work was done to create the snapshot, a lot of code in "ext/node" depends on presence of "Deno" global. This code will be gradually fixed in the follow up PRs to migrate it to import relevant APIs from "internal:" modules. Currently the code from snapshot is not used in any way, and all Node/npm compatibility still uses code from "https://deno.land/std/node" (or from the location specified by "DENO_NODE_COMPAT_URL"). This will also be handled in a follow up PRs. --------- Co-authored-by: crowlkats Co-authored-by: Divy Srivastava Co-authored-by: Yoshiya Hinosawa --- ext/node/polyfills/upstream_modules.ts | 39 ++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 ext/node/polyfills/upstream_modules.ts (limited to 'ext/node/polyfills/upstream_modules.ts') diff --git a/ext/node/polyfills/upstream_modules.ts b/ext/node/polyfills/upstream_modules.ts new file mode 100644 index 000000000..ed8d6faa0 --- /dev/null +++ b/ext/node/polyfills/upstream_modules.ts @@ -0,0 +1,39 @@ +// Copyright 2018-2023 the Deno authors.
