• Quote object properties that are modern Unicode identifiers (#​1349)

  In ES6 and above, an identifier is a character sequence starting with a character in the ID_Start Unicode category and followed by zero or more characters in the ID_Continue Unicode category, and these categories must be drawn from Unicode version 5.1 or above.

  But in ES5, an identifier is a character sequence starting with a character in one of the Lu, Ll, Lt, Lm, Lo, Nl Unicode categories and followed by zero or more characters in the Lu, Ll, Lt, Lm, Lo, Nl, Mn, Mc, Nd, Pc Unicode categories, and these categories must be drawn from Unicode version 3.0 or above.

  Previously esbuild always used the ES6+ identifier validation test when deciding whether to use an identifier or a quoted string to encode an object property but with this release, it will use the ES5 validation test instead:

  // Original code
  x.ꓷꓶꓲꓵꓭꓢꓱ = { ꓷꓶꓲꓵꓭꓢꓱ: y };
  
  // Old output
  x.ꓷꓶꓲꓵꓭꓢꓱ = { ꓷꓶꓲꓵꓭꓢꓱ: y };
  
  // New output
  x["ꓷꓶꓲꓵꓭꓢꓱ"] = { "ꓷꓶꓲꓵꓭꓢꓱ": y };

  This approach should ensure maximum compatibility with all JavaScript environments that support ES5 and above. Note that this means minified files containing Unicode properties may be slightly larger than before.

• Ignore tsconfig.json files inside node_modules (#​1355)

  Package authors often publish their tsconfig.json files to npm because of npm's default-include publishing model and because these authors probably don't know about .npmignore files. People trying to use these packages with esbuild have historically complained that esbuild is respecting tsconfig.json in these cases. The assumption is that the package author published these files by accident.

  With this release, esbuild will no longer respect tsconfig.json files when the source file is inside a node_modules folder. Note that tsconfig.json files inside node_modules are still parsed, and extending tsconfig.json files from inside a package is still supported.

• Fix missing --metafile when using --watch (#​1357)

  Due to an oversight, the --metafile setting didn't work when --watch was also specified. This only affected the command-line interface. With this release, the --metafile setting should now work in this case.

• Add a hidden __esModule property to modules in ESM format (#​1338)

  Module namespace objects from ESM files will now have a hidden __esModule property. This improves compatibility with code that has been converted from ESM syntax to CommonJS by Babel or TypeScript. For example:

  // Input TypeScript code
  import x from "y"
  console.log(x)
  
  // Output JavaScript code from the TypeScript compiler
  var __importDefault = (this && this.__importDefault) || function (mod) {
      return (mod && mod.__esModule) ? mod : { "default": mod };
  };
  Object.defineProperty(exports, "__esModule", { value: true });
  const y_1 = __importDefault(require("y"));
  console.log(y_1.default);

  If the object returned by require("y") doesn't have an __esModule property, then y_1 will be the object { "default": require("y") }. If the file "y" is in ESM format and has a default export of, say, the value null, that means y_1 will now be { "default": { "default": null } } and you will need to use y_1.default.default to access the default value. Adding an automatically-generated __esModule property when converting files in ESM format to CommonJS is required to make this code work correctly (i.e. for the value to be accessible via just y_1.default instead).

  With this release, code in ESM format will now have an automatically-generated __esModule property to satisfy this convention. The property is non-enumerable so it shouldn't show up when iterating over the properties of the object. As a result, the export name __esModule is now reserved for use with esbuild. It's now an error to create an export with the name __esModule.

  This fix was contributed by @​lbwa.
