🗃️ An in-memory JS database optimized for large scale storage on the frontend.

What's Changed

• BlinkDB introduces bulk methods! You can now use insertMany(), updateMany(), and removeMany() to create, update & delete multiple items at once. See the docs for more details.

• These bulk methods are now used in the benchmarks against lokiJS, which shows the massive speed increase:

  BEFORE ( with insert() ):
    comparison for creating 10.000 items:
      lokijs    took 8.61030ms, high 19.76770ms, low 7.18500ms
      blinkdb   took 14.00180ms, high 142.01530ms, low 12.76930ms
  
  AFTER ( with insertMany() ):
    comparison for creating 10.000 items:
      lokijs    took 7.46930ms, high 28.76890ms, low 7.20460ms
      blinkdb   took 3.43980ms, high 25.70130ms, low 3.20480ms
  

• New updateWhere()/removeWhere() functions that update/remove all items that match a given filter.

• New count() method that returns the total number of items in a table (or matching a given filter, if a filter is supplied).

What's Changed

• The query types for BlinkDB have been reworked, and now produce correct type output if the interface of the entity passed to createTable() contains complex union types.
• Indexes can now be built on properties marked as undefined/null.

Breaking changes

• The $ prefix for filters has been removed, and object matching is done with a new where subfilter.

The prefix was used for distinction in object matching, where

const users = await many(userTable, {
  age: { lt: 30 }
});

could mean both "retrieve all items with an age < 30" or "retrieve all items where age is an object matching { lt: 30 }".

This confusion has been fixed by requiring usage of the eq filter or a new where subfilter for object matching. The two queries below produce the same result, namely all items where nested === { prop: "a" }:

const users = await many(userTable, {
  nested: {
    eq: { 
      prop: "a" 
     }
  }
});

const users = await many(userTable, {
  nested: {
    where: {
      prop: "a" // usage of { eq: a } or other filters is allowed here
    }
  }
});

• The equals filter has been renamed to eq.

What's Changed

BlinkDB now uses a more refined query engine which will make it easier to implement sort & limit-based optimizations in the future. Additionally, $and now performs better by choosing the most performant sub query for execution.
