  ([13dbaf2](https://github.com/loopbackio/loopback-next/commit/13dbaf24abad16ac4249cef15f41508d5264ed54))

### BREAKING CHANGES

- **eslint-config:** We are no longer telling eslint to create a default program
  for files not included in `tsconfig.json`. 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.

# [8.0.0](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@7.0.1...@loopback/eslint-config@8.0.0) (2020-05-28)

### Features

- **eslint-config:** add naming convention rules
  ([c8e2143](https://github.com/loopbackio/loopback-next/commit/c8e214392a572a81620133f79c2cc122f89e6862))

### BREAKING CHANGES

- **eslint-config:** @typescript-eslint/typescript-eslint v3.0.0 introduces a
  list of breaking changes. 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)

# [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);
  });
});
```

- **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.

### 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. Please upgrade to version 10 and above. See
  https://nodejs.org/en/about/releases.

# [5.0.0](https://github.com/loopbackio/loopback-next/compare/@loopback/eslint-config@4.1.5...@loopback/eslint-config@5.0.0) (2019-12-09)

### Features

  ([b608120](https://github.com/loopbackio/loopback-next/commit/b608120dbf67e1f93eabd6fa5efe1f6e6630084a))

  ([d74a688](https://github.com/loopbackio/loopback-next/commit/d74a68889fb48d7a1cb7034cb5a8fa8587853b5e))

  ([be6b38b](https://github.com/loopbackio/loopback-next/commit/be6b38b75b2f4c937b742398c9edcbb6c2d1d7c0))

### BREAKING CHANGES

- **eslint-config:** The linter will reject code using `return await` ouside of
  `try` blocks or forgetting to `await` before returning from inside a `try`
  block. Migration guide: use `return` outside of `try` blocks and
  `return await` inside `try` blocks.

- **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`.

See
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#optional-chaining

  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.
