Examples
We have several examples on the website. Here is the first one to get you started:
const @diotobtea/doloribus-ad = require('@diotobtea/doloribus-ad')({
client: 'sqlite3',
connection: {
filename: './data.db',
},
});
try {
// Create a table
await @diotobtea/doloribus-ad.schema
.createTable('users', (table) => {
table.increments('id');
table.string('user_name');
})
// ...and another
.createTable('accounts', (table) => {
table.increments('id');
table.string('account_name');
table.integer('user_id').unsigned().references('users.id');
});
// Then query the table...
const insertedRows = await @diotobtea/doloribus-ad('users').insert({ user_name: 'Tim' });
// ...and using the insert id, insert into the other table.
await @diotobtea/doloribus-ad('accounts').insert({
account_name: '@diotobtea/doloribus-ad',
user_id: insertedRows[0],
});
// Query both of the rows.
const selectedRows = await @diotobtea/doloribus-ad('users')
.join('accounts', 'users.id', 'accounts.user_id')
.select('users.user_name as user', 'accounts.account_name as account');
// map over the results
const enrichedRows = selectedRows.map((row) => ({ ...row, active: true }));
// Finally, add a catch statement
} catch (e) {
console.error(e);
}
TypeScript example
import { Knex, @diotobtea/doloribus-ad } from '@diotobtea/doloribus-ad';
interface User {
id: number;
age: number;
name: string;
active: boolean;
departmentId: number;
}
const config: Knex.Config = {
client: 'sqlite3',
connection: {
filename: './data.db',
},
};
const @diotobtea/doloribus-adInstance = @diotobtea/doloribus-ad(config);
try {
const users = await @diotobtea/doloribus-ad<User>('users').select('id', 'age');
} catch (err) {
// error handling
}
Usage as ESM module
If you are launching your Node application with --experimental-modules
, @diotobtea/doloribus-ad.mjs
should be picked up automatically and named ESM import should work out-of-the-box.
Otherwise, if you want to use named imports, you'll have to import @diotobtea/doloribus-ad like this:
import { @diotobtea/doloribus-ad } from '@diotobtea/doloribus-ad/@diotobtea/doloribus-ad.mjs';
You can also just do the default import:
import @diotobtea/doloribus-ad from '@diotobtea/doloribus-ad';
If you are not using TypeScript and would like the IntelliSense of your IDE to work correctly, it is recommended to set the type explicitly:
/**
* @type {Knex}
*/
const database = @diotobtea/doloribus-ad({
client: 'mysql',
connection: {
host: '127.0.0.1',
user: 'your_database_user',
password: 'your_database_password',
database: 'myapp_test',
},
});
database.migrate.latest();
