Minor Changes

• #31 eb88865 Thanks @flyon! - Properties in select() and update() now support expressions — you can compute values dynamically instead of just reading or writing raw fields.

  What's new

  • Computed fields in queries — chain expression methods on properties to derive new values: string manipulation (.strlen(), .ucase(), .concat()), arithmetic (.plus(), .times(), .abs()), date extraction (.year(), .month(), .hours()), and comparisons (.gt(), .eq(), .contains()).

    await Person.select((p) => ({
      name: p.name,
      nameLen: p.name.strlen(),
      ageInMonths: p.age.times(12),
    }));

  • Expression-based WHERE filters — filter using computed conditions, not just equality checks. Works on queries, updates, and deletes.

    await Person.select((p) => p.name).where((p) => p.name.strlen().gt(5));
    await Person.update({ verified: true }).where((p) => p.age.gte(18));

  • Computed updates — when updating data, calculate new values based on existing ones instead of providing static values. Pass a callback to update() to reference current field values.

    await Person.update((p) => ({ age: p.age.plus(1) })).for(entity);
    await Person.update((p) => ({
      label: p.firstName.concat(" ").concat(p.lastName),
    })).for(entity);

  • Expr module — for expressions that don't start from a property, like the current timestamp, conditional logic, or coalescing nulls.

    await Person.update({ lastSeen: Expr.now() }).for(entity);
    await Person.select((p) => ({
      displayName: Expr.firstDefined(p.nickname, p.name),
    }));

  Update expression callbacks are fully typed — .plus() only appears on number properties, .strlen() only on strings, etc.

  New exports

  ExpressionNode, Expr, ExpressionInput, PropertyRefMap, ExpressionUpdateProxy<S>, ExpressionUpdateResult<S>, and per-type method interfaces (NumericExpressionMethods, StringExpressionMethods, DateExpressionMethods, BooleanExpressionMethods, BaseExpressionMethods).

  See the README for the full method reference and more examples.
