* Add `.js` extension to source file imports * Specify package `exports` in `package.json` Specify package type as `commonjs` (It's good to be specific) * Move all compiled scripts into `lib` directory Remove ./number.js (You can use the compiled ones in `./lib/*`) Tell node that the `esm` directory is type `module` and enable tree shaking. Remove unused files from packages `files` property * Allow importing of package.json * Make library ESM first * - Fix merge conflicts - Refactor `bundleAny` into `defaultInstance.js` and `browserBundle.cjs` - Refactor unit tests to be able to run with plain nodejs (no transpiling) - Fix browser examples * Fix browser and browserstack tests * Fix running unit tests on Node 10 (which has no support for modules) * Fix node.js examples (those are still commonjs) * Remove the need for `browserBundle.cjs` * Generate minified bundle only * [Security] Bump node-fetch from 2.6.0 to 2.6.1 (#1963) Bumps [node-fetch](https://github.com/bitinn/node-fetch) from 2.6.0 to 2.6.1. **This update includes a security fix.** - [Release notes](https://github.com/bitinn/node-fetch/releases) - [Changelog](https://github.com/node-fetch/node-fetch/blob/master/docs/CHANGELOG.md) - [Commits](https://github.com/bitinn/node-fetch/compare/v2.6.0...v2.6.1) Signed-off-by: dependabot-preview[bot] <support@dependabot.com> Co-authored-by: dependabot-preview[bot] <27856297+dependabot-preview[bot]@users.noreply.github.com> * Cleanup console.log * Add integration tests to test the entry points (commonjs/esm, full/number only) * Create backward compatibility error messages in the files moved/removed since v8 * Describe breaking changes in HISTORY.md * Bump karma from 5.2.1 to 5.2.2 (#1965) Bumps [karma](https://github.com/karma-runner/karma) from 5.2.1 to 5.2.2. - [Release notes](https://github.com/karma-runner/karma/releases) - [Changelog](https://github.com/karma-runner/karma/blob/master/CHANGELOG.md) - [Commits](https://github.com/karma-runner/karma/compare/v5.2.1...v5.2.2) Signed-off-by: dependabot-preview[bot] <support@dependabot.com> Co-authored-by: dependabot-preview[bot] <27856297+dependabot-preview[bot]@users.noreply.github.com> Co-authored-by: Lee Langley-Rees <lee@greenimp.co.uk> Co-authored-by: dependabot-preview[bot] <27856297+dependabot-preview[bot]@users.noreply.github.com>
