Bumps esbuild from 0.13.10 to 0.14.2.

Release notes

Sourced from esbuild's releases.

v0.14.2

• Add [ext] placeholder for path templates (#1799)

  This release adds the [ext] placeholder to the --entry-names=, --chunk-names=, and --asset-names= configuration options. The [ext] placeholder takes the value of the file extension without the leading ., and can be used to place output files with different file extensions into different folders. For example, --asset-names=assets/[ext]/[name]-[hash] might generate an output path of assets/png/image-LSAMBFUD.png.

  This feature was contributed by @​LukeSheard.

• Disable star-to-clause transform for external imports (#1801)

  When bundling is enabled, esbuild automatically transforms import * as x from 'y'; x.z() into import {z} as 'y'; z() to improve tree shaking. This avoids needing to create the import namespace object x if it's unnecessary, which can result in the removal of large amounts of unused code. However, this transform shouldn't be done for external imports because that incorrectly changes the semantics of the import. If the export z doesn't exist in the previous example, the value x.z is a property access that is undefined at run-time, but the value z is an import error that will prevent the code from running entirely. This release fixes the problem by avoiding doing this transform for external imports:

  // Original code
  import * as x from 'y';
  x.z();
  // Old output (with --bundle --format=esm --external:y)
  import { z } from "y";
  z();
  // New output (with --bundle --format=esm --external:y)
  import * as x from "y";
  x.z();
  

• Disable calc() transform for numbers with many fractional digits (#1821)

  Version 0.13.12 introduced simplification of calc() expressions in CSS when minifying. For example, calc(100% / 4) turns into 25%. However, this is problematic for numbers with many fractional digits because either the number is printed with reduced precision, which is inaccurate, or the number is printed with full precision, which could be longer than the original expression. For example, turning calc(100% / 3) into 33.33333% is inaccurate and turning it into 33.333333333333336% likely isn't desired. In this release, minification of calc() is now disabled when any number in the result cannot be represented to full precision with at most five fractional digits.

• Fix an edge case with catch scope handling (#1812)

  This release fixes a subtle edge case with catch scope and destructuring assignment. Identifiers in computed properties and/or default values inside the destructuring binding pattern should reference the outer scope, not the inner scope. The fix was to split the destructuring pattern into its own scope, separate from the catch body. Here's an example of code that was affected by this edge case:

  // Original code
  let foo = 1
  try {
    throw ['a', 'b']
  } catch ({ [foo]: y }) {
    let foo = 2
    assert(y === 'b')
  }
  // Old output (with --minify)
  let foo=1;try{throw["a","b"]}catch({[o]:t}){let o=2;assert(t==="b")}
  // New output (with --minify)
  let foo=1;try{throw["a","b"]}catch({[foo]:t}){let o=2;assert(t==="b")}
