eslint-plugin-drizzle

For cases where it's impossible to perform type checks for specific scenarios, or where it's possible but error messages would be challenging to understand, we've decided to create an ESLint package with recommended rules. This package aims to assist developers in handling crucial scenarios during development

Big thanks to @Angelelz for initiating the development of this package and transferring it to the Drizzle Team's npm

Install

[ npm | yarn | pnpm | bun ] install eslint eslint-plugin-drizzle

You can install those packages for typescript support in your IDE

[ npm | yarn | pnpm | bun ] install @typescript-eslint/eslint-plugin @typescript-eslint/parser

Usage

Create a .eslintrc.yml file, add drizzle to the plugins, and specify the rules you want to use. You can find a list of all existing rules below

root: true
parser: '@typescript-eslint/parser'
parserOptions:
  project: './tsconfig.json'
plugins:
  - drizzle
rules:
  'drizzle/enforce-delete-with-where': "error"
  'drizzle/enforce-update-with-where': "error"

All config

This plugin exports an all config that makes use of all rules (except for deprecated ones).

root: true
extends:
  - "plugin:drizzle/all"
parser: '@typescript-eslint/parser'
parserOptions:
  project: './tsconfig.json'
plugins:
  - drizzle

At the moment, all is equivalent to recommended

root: true
extends:
  - "plugin:drizzle/recommended"
parser: '@typescript-eslint/parser'
parserOptions:
  project: './tsconfig.json'
plugins:
  - drizzle

Rules

enforce-delete-with-where: Enforce using delete with the.where() clause in the .delete() statement. Most of the time, you don't need to delete all rows in the table and require some kind of WHERE statements.

Optionally, you can define a drizzleObjectName in the plugin options that accept a string or string[]. This is useful when you have objects or classes with a delete method that's not from Drizzle. Such a delete method will trigger the ESLint rule. To avoid that, you can define the name of the Drizzle object that you use in your codebase (like db) so that the rule would only trigger if the delete method comes from this object:

Example, config 1:

"rules": {
  "drizzle/enforce-delete-with-where": ["error"]
}

class MyClass {
  public delete() {
    return {}
  }
}

const myClassObj = new MyClass();

// ---> Will be triggered by ESLint Rule
myClassObj.delete()

const db = drizzle(...)
// ---> Will be triggered by ESLint Rule
db.delete()

Example, config 2:

"rules": {
  "drizzle/enforce-delete-with-where": ["error", { "drizzleObjectName": ["db"] }],
}

class MyClass {
  public delete() {
    return {}
  }
}

const myClassObj = new MyClass();

// ---> Will NOT be triggered by ESLint Rule
myClassObj.delete()

const db = drizzle(...)
// ---> Will be triggered by ESLint Rule
db.delete()

enforce-update-with-where: Enforce using update with the.where() clause in the .update() statement. Most of the time, you don't need to update all rows in the table and require some kind of WHERE statements.

Optionally, you can define a drizzleObjectName in the plugin options that accept a string or string[]. This is useful when you have objects or classes with a delete method that's not from Drizzle. Such as update method will trigger the ESLint rule. To avoid that, you can define the name of the Drizzle object that you use in your codebase (like db) so that the rule would only trigger if the delete method comes from this object:

Example, config 1:

"rules": {
  "drizzle/enforce-update-with-where": ["error"]
}

class MyClass {
  public update() {
    return {}
  }
}

const myClassObj = new MyClass();

// ---> Will be triggered by ESLint Rule
myClassObj.update()

const db = drizzle(...)
// ---> Will be triggered by ESLint Rule
db.update()

Example, config 2:

"rules": {
  "drizzle/enforce-update-with-where": ["error", { "drizzleObjectName": ["db"] }],
}

class MyClass {
  public update() {
    return {}
  }
}

const myClassObj = new MyClass();

// ---> Will NOT be triggered by ESLint Rule
myClassObj.update()

const db = drizzle(...)
// ---> Will be triggered by ESLint Rule
db.update()
