¿Cómo puedo obtener la salida Json de Sqlite3?

Question

Hola, escribí un SQL para obtener información de 2 tablas, pero cuando quiero devolver los datos, no conozco el índice para hacerlo en el momento adecuado. ¿Qué debo hacer y hay alguna forma de obtener la respuesta de Json desde el primero en lugar de cada método?

mi función:

const searchAntibodies = (
  index: number,
  amount: number,
  information: string,
  startDate: string,
  endDate: string,
) => {
  return new Promise<Antibodies[]>((resolve, reject) => {
    let antibodies: Antibodies[] = [];
    db.serialize(() => {
      db.each(`SELECT id, name as antibodyName FROM Antibodies WHERE
              id IN 
              (SELECT id FROM Antibodies WHERE name LIKE ?
              UNION all
              SELECT antiId FROM AssignedColors WHERE name LIKE ?
              UNION all
              SELECT antiId FROM AssignedReactivities WHERE name LIKE ?)
              AND dateOfCreation >= ? AND dateOfCreation <= ?
              ORDER BY dateOfCreation DESC LIMIT ? OFFSET ?;`
        , [`%${information}%`, `%${information}%`, `%${information}%`, startDate, endDate, amount, index]
        , (err, antibody: Antibodies) => {
          if (err) {
            reject(err.message);
          } else {
            db.all('SELECT name, locations, colorId FROM AssignedColors WHERE antiId = ?', [antibody.id], (err, colors) => {
              if (err) {
                reject(err.message);
              } else {
                antibody.colors = colors;
                antibodies.push(antibody);
                if (antibodies.length === 10) {
                  resolve(antibodies)
                }
              }
            });
          }
        });
    });
  });
}

mi resultado esperado:

[   {
    id: 1999,
    antibodyName: 'Antibody 1999',
    colors: [ [Object], [Object], [Object], [Object], [Object] ]   },   {
    id: 1995,
    antibodyName: 'Antibody 1995',
    colors: [ [Object], [Object], [Object], [Object], [Object] ]   },   {
    id: 1994,
    antibodyName: 'Antibody 1994',
    colors: [ [Object], [Object], [Object], [Object], [Object] ]   },   {
    id: 1993,
    antibodyName: 'Antibody 1998',
    colors: [ [Object], [Object], [Object], [Object], [Object] ]   },   {
    id: 1997,
    antibodyName: 'Antibody 1997',   } ]

Ok después de buscar mucho encontré la respuesta. En realidad, si no establece tipos para la primera función de devolución de llamada, puede obtener una segunda función de devolución de llamada para cuando se complete. Aquí está mi resultado:

const getAntibodies = (
  index: number,
  amount: number,
  startDate: number,
  endDate: number,
  orderBy: string,
  orderType: string,
) => {
  return new Promise<Antibodies[]>((resolve, reject) => {
    let antibodies: Antibodies[] = [];
    let totalCount: number;
    let sql = 'SELECT id, name as antibodyName, dateOfCreation FROM Antibodies ';
    let params = [amount, index];
    if (startDate !== 0 || endDate !== 0) {
      sql += `WHERE dateOfCreation >= ? AND dateOfCreation <= ? 
                ORDER BY ${orderBy} ${orderType} LIMIT ? OFFSET ?;`;
      params.unshift(startDate, endDate);
    } else {
      sql += `ORDER BY ${orderBy} ${orderType} LIMIT ? OFFSET ?;`;
    }
    db.serialize(() => {
      db.each(sql,
        params
        , async (err, antibody) => {
          if (err) {
            reject(err.message);
          } else {
            await getColors(antibody.id).then((colors) => {
              antibody.colors = colors;
              antibodies.push(antibody);
              if (antibodies.length === totalCount) {
                resolve(antibodies);
              }
            }).catch((err) => {
              reject(err);
            });
          }
        }, (err, count) => {
          if (err) {
            reject(err.message)
          } else {
            if (count === 0) {
              resolve(antibodies);
            } else {
              totalCount = count;
            }
          }
        });
    });
  });
}

const getColors = (id: number) => {
  return new Promise<Color[]>((resolve, reject) => {
    db.serialize(() => {
      db.all('SELECT name, locations, colorId FROM AssignedColors WHERE antiId = ?', [id], (err, colors: Color[]) => {
        if (err) {
          reject(err.message)
        } else {
          resolve(colors);
        }
      });
    });
  });
}
