chore(deps-dev): bump esbuild from 0.15.5 to 0.15.7

[dependabot]

Bumps esbuild from 0.15.5 to 0.15.7.

Release notes

Sourced from esbuild's releases.

v0.15.7

• Add --watch=forever to allow esbuild to never terminate (#1511, #1885)

  Currently using esbuild's watch mode via --watch from the CLI will stop watching if stdin is closed. The rationale is that stdin is automatically closed by the OS when the parent process exits, so stopping watch mode when stdin is closed ensures that esbuild's watch mode doesn't keep running forever after the parent process has been closed. For example, it would be bad if you wrote a shell script that did esbuild --watch & to run esbuild's watch mode in the background, and every time you run the script it creates a new esbuild process that runs forever.

  However, there are cases when it makes sense for esbuild's watch mode to never exit. One such case is within a short-lived VM where the lifetime of all processes inside the VM is expected to be the lifetime of the VM. Previously you could easily do this by piping the output of a long-lived command into esbuild's stdin such as sleep 999999999 | esbuild --watch &. However, this possibility often doesn't occur to people, and it also doesn't work on Windows. People also sometimes attempt to keep esbuild open by piping an infinite stream of data to esbuild such as with esbuild --watch </dev/zero & which causes esbuild to spin at 100% CPU. So with this release, esbuild now has a --watch=forever flag that will not stop watch mode when stdin is closed.

• Work around PATH without node in install script (#2519)

  Some people install esbuild's npm package in an environment without the node command in their PATH. This fails on Windows because esbuild's install script runs the esbuild command before exiting as a sanity check, and on Windows the esbuild command has to be a JavaScript file because of some internal details about how npm handles the bin folder (specifically the esbuild command lacks the .exe extension, which is required on Windows). This release attempts to work around this problem by using process.execPath instead of "node" as the command for running node. In theory this means the installer can now still function on Windows if something is wrong with PATH.

v0.15.6

• Lower for await loops (#1930)

  This release lowers for await loops to the equivalent for loop containing await when esbuild is configured such that for await loops are unsupported. This transform still requires at least generator functions to be supported since esbuild's lowering of await currently relies on generators. This new transformation is mostly modeled after what the TypeScript compiler does. Here's an example:

  async function f() {
    for await (let x of y)
      x()
  }

  The code above will now become the following code with --target=es2017 (omitting the code for the __forAwait helper function):

  async function f() {
    try {
      for (var iter = __forAwait(y), more, temp, error; more = !(temp = await iter.next()).done; more = false) {
        let x = temp.value;
        x();
      }
    } catch (temp) {
      error = [temp];
    } finally {
      try {
        more && (temp = iter.return) && await temp.call(iter);
      } finally {
        if (error)
          throw error[0];
      }
    }
  }

• Automatically fix invalid supported configurations (#2497)

  The --target= setting lets you tell esbuild to target a specific version of one or more JavaScript runtimes such as chrome80,node14 and esbuild will restrict its output to only those features supported by all targeted JavaScript runtimes. More recently, esbuild introduced the --supported: setting that lets you override which features are supported on a per-feature basis. However, this now lets you configure nonsensical things such as --supported:async-await=false --supported:async-generator=true. Previously doing this could result in esbuild building successfully but producing invalid output.

  Starting with this release, esbuild will now attempt to automatically fix nonsensical feature override configurations by introducing more overrides until the configuration makes sense. So now the configuration from previous example will be changed such that async-await=false implies async-generator=false. The full list of implications that were introduced is below:
