In version typescript 4.1 the option "noUncheckedIndexedAccess" has been added.
I would strongly advise deno to support the ability to set this option.

支持自动检测框架的覆盖范围仅仅支持了几个常见前端框架和函数，还可以拓展更多的框架和语言来提升体验

这块的实现是基于配置式的，可以比较轻松拓展一个新框架的支持
https://github.com/TencentCloudBase/cloudbase-framework/blob/master/packages/framework-core/src/detect-frameworks/frameworks.ts

大家可以通过这个快速参与进核心代码的开发当中，目前可以考虑支持的框架和技术有 Hexo, Egg, Koa, Express, Koa , Docker 容器等

• Vue
• React
• V

Not sure if this is the correct way to do it, but I wanted to save a cache script I could easily run.

"cache": {
      "desc": "Cache versions and update lock file",
      "cmd": "deno cache server.ts --lock-write",
      "lock": "./lock.json"
}

The result however when running denon cache is an endless loop instead of just executing it once, looks like this:

![Skärmavbild

error[no-self-assign]: length
  --> /Users/lucacasonato/projects/github.com/denoland/deno/op_crates/fetch/22_body.js:80:23
   |
80 |       second.length = second.length;
   |                       ^^^^^^^^^^^^^

   = help: Mistake

This error message should be reworked. It need a better help text, and a better error text.

There are a large number of potential error and result types contained in JavaScript.rs. When building that module, I made the decision to convert all errors into IoError via calls to map.

Deno solves this problem by using AnyHow, which they expose via the deno_core crate. They also expose helper functions like "deno_core::error::generic_error" to make using that error system easier.

Since deno

At the moment you need to do:

# Compile the handler (and fetch dependencies into DENO_DIR).
DENO_DIR=.deno_dir deno fetch hello.ts

# This is the "remapping" step:
cp -R .deno_dir/gen/file/$PWD/ .deno_dir/LAMBDA_TASK_ROOT
# Note: We do the inverse of this operation in bootstrap.

zip lambda.zip -x '.deno_dir/gen/file/*' -r .d
