Strongly typed validation

Example

enumColor{Red,Green,Blue}classSomeObject{string?:string;}classModel{color:Color;string:string;number:number;boolean:boolean;date:Date;stringArray:string[];numberArray:number[];booleanArray:boolean[];dateArray:Date[];enumArray:Color[];object:SomeObject;objectArray:SomeObject[];}

enumColor{Red,Green,Blue}classSomeObject{    @IsOptional()    @IsString()string?:string;}classModel{    @IsEnum(Color)color:Color;    @IsString()string:string;    @IsNumber()number:number;    @IsBoolean()boolean:boolean;    @IsDate()date:Date;    @IsString({each:true})stringArray:string[];    @IsNumber({},{each:true})numberArray:number[];    @IsBoolean({each:true})booleanArray:boolean[];    @IsDate({each:true})dateArray:Date[];    @IsEnum(Color,{each:true})enumArray:Color[];    @ValidateNested()object:SomeObject;    @ValidateNested({each:true})objectArray:SomeObject[];}

Get started

Install rule with dev flag:

npm i tslint-class-validator-rule -D

tslint configuration

{"rulesDirectory": ["tslint-class-validator-rule"],"rules": {"no-property-without-decorator":true    }}

tslint -p . --fix

Add middleware (nestjs)

app.useGlobalPipes(newValidationPipe({forbidUnknownValues:true}));

TODO

- Add imports

- file/folder name option, to support '**/*model.ts'
