如何解决转换TypeOrm实体以响应友好的Typescript DTO

我想将大约200个typeOrm实体引用到我的Typescript React代码中。

这是一个monorepo项目，例如：

-|-后 |-共享 |-前

我的实体是这样的：

import {Column,Entity,JoinColumn,ManyToOne,OneToOne} from "typeorm";
import {childRelationOptions,parentEagerRelationOptions} from "../typeorm-helper/src";
import {Nationality} from "./cold-data/nationality.entity";
import {Situation} from "./cold-data/situation.entity";
import {Document} from "./document.entity";
import {
    IsDate,IsMobilePhone,IsNotEmpty,IsNotEmptyObject,IsOptional,IsString,Matches,ValidateIf,ValidateNested
} from "class-validator";
import {ExportFor} from "../export/src";
import {UserRoleEnum} from "./User-role.enum";
import {VersionedBaseWithId} from "./versioned-base-with-id.entity";
import {CandidateFile} from "./candidate-file.entity";
import {DocumentTypeEnum} from "./cold-data/document-type.entity";
import {alwaysValidate,validateForSave,validateForSubmit} from "../class-validator-test-helper/src";
import {Empty,Fake,getEmpty,getFake} from "../context";
/**
 * Contains all candidate personal data
 */
import * as faker from "faker";

@Entity()
export class Profile extends VersionedBaseWithId {

    @OneToOne(() => CandidateFile,(e: CandidateFile) => e.profile,childRelationOptions)
    @JoinColumn()
    public candidateFile: CandidateFile
    // noinspection JSUnusedLocalSymbols
    @Fake((context) => {
        const d: Document = context.japd || getFake(new Document(),context)
        d.type.id = DocumentTypeEnum.JAPD
        return d
    })
    @Empty((context) => {
        const d: Document = getEmpty(new Document(),context)
        d.type.id = DocumentTypeEnum.JAPD
        return d
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateIf(o => o.nationality?.name === "Française",validateForSubmit)
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(type => Document,parentEagerRelationOptions)
    public JAPDDocument: Document

    @Fake(faker.random.boolean)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @Column({nullable: true})
    funded: boolean
    @Fake(faker.random.boolean)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @Column({nullable: true})
    thirdPartyTime: boolean
    @Fake(faker.address.streetAddress)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @IsString(alwaysValidate)
    @Column({nullable: true})
    address1: string
    @Fake(faker.address.streetAddress)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(alwaysValidate)
    @IsString({always: true})
    @Column({nullable: true})
    address2: string
    @Fake(faker.address.zipCode,'#####')
    @ExportFor([UserRoleEnum.SECRETARY])
    @Matches(/^[0-9\- a-zA-Z]+|[0-9]{0}$/,{always: true})
    @IsOptional(validateForSave)
    @Column({nullable: true})
    zipCode: string
    @Fake(faker.address.city)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(validateForSave)
    @IsString(alwaysValidate)
    @Column({nullable: true})
    city: string
    @Fake(faker.phone.phoneNumber,'065######')
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @IsOptional(validateForSave)
    @IsMobilePhone(undefined,undefined,{always: true})
    @Column({nullable: true})
    phone: string
    @Fake(faker.date.past,10,new Date(2001,1))
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsDate({always: true})
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @IsOptional(validateForSave)
    @Column({nullable: true})
    birthDate: Date
    @Fake(faker.address.city)
    @ExportFor([UserRoleEnum.SECRETARY])
    @IsString({always: true})
    @IsOptional(validateForSave)
    @IsNotEmpty(validateForSubmit)
    @IsOptional(alwaysValidate)
    @Column({nullable: true})
    birthPlace: string
    @Fake((context) => {
        return context.nationality
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateNested()
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(() => Nationality,{cascade: false})
    nationality: Nationality
    @Fake((context) => {
        return context.situation
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(() => Situation,{cascade: false})
    situation: Situation
    @Fake((context) => {
        const d: Document = context.avatarDocument || getFake(new Document(),context)
        d.type.id = DocumentTypeEnum.AVATAR
        return d
    })
    @Empty((context) => {
        const d: Document = getEmpty(new Document(),context)
        d.type.id = DocumentTypeEnum.AVATAR
        return d
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(() => Document,parentEagerRelationOptions)
    avatarDocument: Document

    @Fake((context) => {
        const d: Document = context.cv || getFake(new Document(),context)
        d.type.id = DocumentTypeEnum.CV
        return d
    })
    @Empty((context) => {
        const d: Document = getEmpty(new Document(),context)
        d.type.id = DocumentTypeEnum.CV
        return d
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(() => Document,parentEagerRelationOptions)
    cvDocument: Document
// noinspection JSUnusedLocalSymbols
    @Fake((context) => {
        const d: Document = context.thirdPartyTimeDocument || getFake(new Document(),context)
        d.type.id = DocumentTypeEnum.THIRD_PARTY_TIME
        return d
    })
    @Empty((context) => {
        const d: Document = getEmpty(new Document(),context)
        d.type.id = DocumentTypeEnum.THIRD_PARTY_TIME
        return d
    })
    @ManyToOne(type => Document,parentEagerRelationOptions)
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateIf((o: Profile) => o.thirdPartyTime,validateForSubmit)
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    thirdPartyTimeDocument: Document

    @Fake((context) => {
        const d: Document = context.idCardDocument || getFake(new Document(),context)
        d.type.id = DocumentTypeEnum.ID_CARD
        return d
    })
    @Empty((context) => {
        const d: Document = getEmpty(new Document(),context)
        d.type.id = DocumentTypeEnum.ID_CARD
        return d
    })
    @ExportFor([UserRoleEnum.SECRETARY])
    @ValidateNested(alwaysValidate)
    @IsNotEmptyObject(validateForSubmit)
    @IsOptional(validateForSave)
    @ManyToOne(() => Document,parentEagerRelationOptions)
    idCardDocument: Document

    constructor() {
        super();
    }
}

我想为每个实体生成一个DTO，目标可能是拥有类似.d.ts文件的内容：

import { Nationality } from "./cold-data/nationality.entity";
import { Situation } from "./cold-data/situation.entity";
import { Document } from "./document.entity";
import { VersionedBaseWithId } from "./versioned-base-with-id.entity";
import { CandidateFile } from "./candidate-file.entity";
export declare class Profile extends VersionedBaseWithId {
    candidateFile: CandidateFile;
    JAPDDocument: Document;
    funded: boolean;
    thirdPartyTime: boolean;
    address1: string;
    address2: string;
    zipCode: string;
    city: string;
    phone: string;
    birthDate: Date;
    birthPlace: string;
    nationality: Nationality;
    situation: Situation;
    avatarDocument: Document;
    cvDocument: Document;
    thirdPartyTimeDocument: Document;
    idCardDocument: Document;
    constructor();
}

如何与React应用共享没有装饰器的代码？

解决方法

我尝试过：

"generate:dto": "yarn workspace back build && rm -rf dto && find ../back/dist/ -name '*.entity.d.ts' | cpio -pdm  . | mv back/dist dto",

它生成了一个包含所有d.ts文件的文件夹
