Duka biyu shahararrun ORMs na Node.js ne da suke tsara abubuwa zuwa tebura na SQL, amma sun fito daga zamanni daban-daban. Sequelize shi ne zaɓin da ya girme, mai ba da fifiko ga JavaScript, wanda aka gwada a yaƙi; TypeORM shi ne sabo, mai ba da fifiko ga TypeScript, mai gudana ta decorator. Zaɓin da ya dace galibi yana dogara ne da yawan darajar da kake ba wa typing na asali kwatankwacin balaga da aka tabbatar.
| TypeORM | Sequelize |
|---|
| TypeScript | Na asali, bisa decorator | An ɗora a kai; typing mai rauni |
| Tsari | Data Mapper da Active Record | Active Record kaɗai |
| Ma'anar model | Classes masu ado | define() / classes, yawan kalmomi |
| Balaga | Sabo, tarihin fitarwa mara sanyi | Balagagge sosai, tsayayye, babban al'umma |
| Queries masu rikitarwa | QueryBuilder, har yanzu yana turawa raw SQL | Query DSL, yana zubewa raw SQL kuma |
| Migrations | CLI, samar ta atomatik (na iya yin hayaniya) | sequelize-cli, balagagge |
| Mafi kyau da | NestJS / backends masu nau'i | JS mai sauƙi / stacks masu son legacy |
// TypeORM — entity mai ado + repository
@Entity() class User { @PrimaryGeneratedColumn() id: number; @Column() email: string; }
const u = await ds.getRepository(User).findOne({ where: { email } });
// Sequelize — model na define() + finder
const User = sequelize.define("User", { email: DataTypes.STRING });
const u = await User.findOne({ where: { email } });
Wannan tambaya ce ta yanke shawara ta gargajiya na matakin senior: masu hira ba sa neman wanda ya yi nasara, suna duba ko kana tunani game da sasantawa. Duka ORMs suna warware matsala iri ɗaya kuma duka suna zubewa a kan SQL mai rikitarwa; abubuwan da suke banbanta su ne ergonomics na TypeScript, tsarin da ake goyon baya, da balagar ecosystem. Iya tsara waɗannan zuwa harshen ƙungiyarka, stack, da rikitarwar query — da faɗin yaushe babu ɗaya shi ne kayan aiki mai kyau — shi ne abin da yake raba zaɓin gine-gine da aka yi tunani a kai daga na tsoho.
Ɗakin karatu na tambayoyin hira na IT tare da amsoshi cikakke — daga Junior zuwa Senior.
