CHANGELOG.md

fast-copy CHANGELOG

4.0.2

• #112 - Prevent generators from attempting to be copied (fixes #111)

4.0.1

• #110 - Fix legacy types not aligning with types from build package

4.0.0

BREAKING CHANGES

• The default copy method is now a named export, and the default export has been removed.
• Legacy environment support has been removed; Symbol, WeakMap, and RegExp.prototype.flags are now expected to be present.
• createCopier now receives an object of options. The methods passed previously are namespaced under the methods key in that options object.
• createStrictCopier has been removed; please use the strict option passed to createCopier

3.0.2

• #95 - Add support for objects that have a prototype with no constructor

3.0.1

• #78 - Work when running Node process with --disable-proto=throw (thanks @castarco)

3.0.0

Breaking changes

• Exports are now always named, so the .default suffix is required when accessing
  • CommonJS in Node => const copy = require('fast-copy').default;
  • UMD global via CDN => const copy = globalThis['fast-copy'].default;
• copy.strict is no longer available; it is now available as the explicit copyStrict named import
• Options have been removed
  • isStrict option has been replaced with importing the separate copyStrict method
  • realm has been removed entirely, as instanceof is no longer used internally
• The FastCopy namespace in typings has been removed in favor of explicit import of available types

Enhancements

• Support exports option, to have bettern handling for different environments (ESM vs CJS vs UMD) and improve tree-shaking when supported
• Can now create a custom copier (either standard or strict), allowing maximum performance for specific use-cases
• Small speed improvements when handling certain object types

Bug fixes

• Correctly handle primitive wrappers, e.g. new String('foo')

2.1.7

• Republish of 2.1.6, as the release process failed mid-publish

2.1.6

• Revert #69 and #71, as they broke the package for NodeJS consumption (will be reintroduced in v3, as breaking changes are required)

2.1.5 - DO NOT USE

• Ensure "type": "module" is set to allow ESM in NodeJS to work #71

2.1.4 - DO NOT USE

• Provide "exports" definition in package.json #69 (thanks @liteoood)

2.1.3

• Fix source maps not referencing source code #65

2.1.2

• Support constructor property override on object #60
• Provide better support for constructor override on non-plain object types #61
• Remove tslint in favor of @typescript-eslint #62

2.1.1

• Fix ESM-to-CommonJS issue when using TSC to consume #37
• Modify Blob cloning to use blob.slice() instead of new Blob() for speed

2.1.0

• Support cloning Blob #31 (thanks @fratzigner)
• Fix cloning descriptors that only are getters / setters in strict mode
• Handle errors when defining properties in strict mode

2.0.5

• Fix issue copying objects referenced multiple times in source #28 (thanks @darkowic)

2.0.4

• Cache length of arrays for faster iteration #22
• Update dev dependencies and types

2.0.3

• Add safety to constructing native objects (fixes #19)

2.0.2

• Manually coalesce options instead of use destructuring (performance)

2.0.1

• Fix typings declarations - #17

2.0.0

• Rewrite in TypeScript
• Add strict mode (for more accurate and thorough copying, at the expense of less performance)

BREAKING CHANGES

• Second parameter is now an object of options

1.2.4

• Ensure Date copy uses realm-specific constructor

1.2.3

• Support custom prototype applied to plain object via Object.create()

1.2.2

• Support copy of extensions of native Array with alternative push() method

1.2.1

• Under-the-hood optimizations per recommendations from #7

1.2.0

• Add support for multiple realms

1.1.2

• Optimize order of operations for common use cases

1.1.1

• Fix cache using WeakSet when there was support for WeakMaps instead of WeakSets (in case one was polyfilled but not the other)

1.1.0

• Add TypeScript and FlowType bindings

1.0.1

• Activate tree-shaking

1.0.0

• Initial release
