If you start receiving linter errors after upgrade, you can either add `createDefaultProgram` to your eslint config manually, modify your `tsconfig` file to include all files checked by eslint, or exclude the problematic files from linting by adding them to `.eslintignore` file. In projects scaffolded via `lb4 app`, we recommend to add `.eslintrc.js` file to `.eslintignore` list.

Existing code might violate the new or changed rules. Manual fixes may be required. See more details at: https://github.com/typescript-eslint/typescript-eslint/releases/tag/v3.0.0 ## [7.0.1](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@7.0.0...@loopback/eslint-config@7.0.1) (2020-05-20) **Note:** Version bump only for package @loopback/eslint-config # [7.0.0](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.6...@loopback/eslint-config@7.0.0) (2020-05-19) ### Features * replace eslint rule `no-invalid-this` with TypeScript-aware one ([b2f21f7](https://github.com/loopbackio/loopback-next/commit/b2f21f78c28c71b59bbed8f1a42c4b663c85f507)) * **eslint-config:** upgrade to ESLint 7.x ([5c3e3c2](https://github.com/loopbackio/loopback-next/commit/5c3e3c247b9d6f47a1b5d861ffe3eff35ed5caf0)) ### BREAKING CHANGES * In code accessing `this` variable, eslint-ignore comment for `no-invalid-this` will no longer work. You can either change those comments to disable `@typescript-eslint/no-invalid-this`, or better tell TypeScript what is the type of `this` in your function. A TypeScript example: ```ts describe('my mocha suite', function(this: Mocha.Suite) { this.timeout(1000); it('is slow', function(this: Mocha.Context) { this.timeout(2000); }); }) ``` A JavaScript example: ```js describe('my mocha suite', /** @this {Mocha.Suite} */ function() { this.timeout(1000); it('is slow', /** @this {Mocha.Context} */ function() { this.timeout(2000); }); }) ``` Signed-off-by: Miroslav Bajtoš <mbajtoss@gmail.com> * **eslint-config:** ESLint 7.x changes how plugins references in the shared config are resolved. The following is quoted from https://eslint.org/blog/2020/05/eslint-v7.0.0-released: > ESLint will now resolve plugins relative to the entry configuration file. This means that shared configuration files that are located outside the project can now be colocated with the plugins they require. > Starting in ESLint v7, configuration files and ignore files passed to ESLint using the --config path/to/a-config and --ignore-path path/to/a-ignore CLI flags, respectively, will resolve from the current working directory rather than the file location. This allows for users to utilize shared plugins without having to install them directly in their project. ## [6.0.6](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.5...@loopback/eslint-config@6.0.6) (2020-05-07) **Note:** Version bump only for package @loopback/eslint-config ## [6.0.5](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.4...@loopback/eslint-config@6.0.5) (2020-04-29) **Note:** Version bump only for package @loopback/eslint-config ## [6.0.4](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.3...@loopback/eslint-config@6.0.4) (2020-04-22) **Note:** Version bump only for package @loopback/eslint-config ## [6.0.3](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.2...@loopback/eslint-config@6.0.3) (2020-04-08) **Note:** Version bump only for package @loopback/eslint-config ## [6.0.2](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.1...@loopback/eslint-config@6.0.2) (2020-03-24) **Note:** Version bump only for package @loopback/eslint-config ## [6.0.1](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@6.0.0...@loopback/eslint-config@6.0.1) (2020-03-17) **Note:** Version bump only for package @loopback/eslint-config # [6.0.0](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@5.0.3...@loopback/eslint-config@6.0.0) (2020-03-05) ### chore * remove support for Node.js v8.x ([4281d9d](https://github.com/loopbackio/loopback-next/commit/4281d9df50f0715d32879e1442a90b643ec8f542)) ### Features * **eslint-config:** disallow non-null assertions after optional chain ([6fdc2b5](https://github.com/loopbackio/loopback-next/commit/6fdc2b524b72a2cca08307e5d1a66c360c3ceb5a)), closes [#4675](https://github.com/loopbackio/loopback-next/issues/4675) ### BREAKING CHANGES * **eslint-config:** eslint rule `@typescript-eslint/no-non-null-asserted-optional-chain` is set to `error` which may break existing lint tests. * Node.js v8.x is now end of life.

Migration guide: use `return` outside of `try` blocks and `return await` inside `try` blocks. Signed-off-by: Miroslav Bajtoš <mbajtoss@gmail.com> * **eslint-config:** the `@typescript-eslint/prefer-nullish-coalescing` rule prefers nullish coalescing, for example, `ttl ?? 5000` over `ttl || 5000`. See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#nullish-coalescing * **eslint-config:** the `@typescript-eslint/prefer-optional-chain` rule will report violations if optional chaining is not used. For example, it prefers `options?.ttl` over `options && options.ttl`.

To upgrade your project using our eslint-config, bump up eslint version in your package.json file to "^6.0.0". The new eslint version added new recommended rules, most notably "require-atomic-updates" and "no-prototype-builtins". You may get new linting errors after upgrade, fix them by changing your code or adding eslint-ignore comments as needed. ## [1.1.2](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@1.1.1...@loopback/eslint-config@1.1.2) (2019-06-17) **Note:** Version bump only for package @loopback/eslint-config ## [1.1.1](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@1.1.0...@loopback/eslint-config@1.1.1) (2019-06-06) **Note:** Version bump only for package @loopback/eslint-config # [1.1.0](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@1.0.0-3...@loopback/eslint-config@1.1.0) (2019-06-03) ### Features * replace tslint with eslint ([44185a7](https://github.com/loopbackio/loopback-next/commit/44185a7)) * **eslint-config:** allow detection of tsconfig file ([5c16db6](https://github.com/loopbackio/loopback-next/commit/5c16db6)) # [1.0.0-3](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@1.0.0-2...@loopback/eslint-config@1.0.0-3) (2019-05-31) **Note:** Version bump only for package @loopback/eslint-config # 1.0.0-2 (2019-05-30) ### Features * **build:** add eslint scripts and default configs ([a6abe86](https://github.com/loopbackio/loopback-next/commit/a6abe86))
