Yuanlin Lin	0d7fa2f912	[frameworks] Updated Umi.js logo (#7470 ) Co-authored-by: Andy <AndyBitz@users.noreply.github.com>	2022-02-22 19:59:32 +01:00
Nathan Rajlich	3b646880e7	[node] Use `NodejsLambda` class (#7436 ) Updates `@vercel/node` to utilize the `NodejsLambda` class so that it doesn't need to explicitly bundle in the launcher/bridge files into the build result. This reduces the complexity of the Builder and is a cleaner separation of concerns. The `helpers.test.ts` file has been moved to `@vercel/node-bridge` so it's being removed in this PR as well.	2022-02-22 16:57:11 +00:00
