v0.4.0

• BREAKING CHANGES: remove ByteCursor methods

  To make bare-ts/lib API uniform, methods of ByteCursor are replaced by regular functions.

    import * as bare from "@bare-ts/lib"
  
    const bc = new bare.ByteCursor(new Uint8Array(5), bare.Config({}))
  - bc.check(5)
  - bc.reserve(5)
  - bc.read(5)
  + bare.check(bc, 5)
  + bare.reserve(bc, 5)
  + bare.readUnsafeU8FixedArray(bc, 5)

• BREAKING CHANGES: remove textDecoderThreshold and textEncoderThreshold configuration

  Calls to native TextDecoder.decode and TextEncoder.encode have a fixed cost.
  This cost outperforms the native performance to decode and encode small strings.

  bare-ts uses a custom implementation to decode and encode small strings.
  The choice between the custom and the native codecs is based on thresholds.
  These threshold were configurable via textDecoderThreshold and textEncoderThreshold config properties.

  This is not clear whether this configuration is worth to expose.
  Most of decoded and encoded strings are small.
  Fixed thresholds seem fair enough.

• Assertions and development mode

  Previously, bare-ts enabled a few assertions to check some function arguments.
  For instance, the following code could trigger an AssertionError:

  import * as bare from "@bare-ts/lib"
  
  const bc = new bare.ByteCursor(new Uint8Array(5), bare.Config({}))
  bare.writeU8(bc, 2**10) // AssertionError: too large number

  Assertions are now disabled by default.
  They are enabled under the following condition:

  • The code is executed under node with NODE_ENV=development

  • The code is executed or bundled under development condition.

  New assertions were added to improve error reporting on development.
  More assertions could be added in the future.

  Because assertions can be disabled, we improved the code robustness:
  All uint/int writters truncate their input to ensure that the number of written bytes is bounded.

v0.3.0

• Full compliance to IEEE-754 (floating point numbers)

  NaN is now a valid value for f32 and f64.

• Remove {read,write}Void

• Make @bare-ts/lib platform-agnostic

  Use your favorite ESM-ready CDN and simply import @bare-ts/lib.
  This was made possible by removing the dependency over node:assert.

v0.2.0

• Improve performance for reading and writing strings

• Improve performance for reading variable integers encoded on a single byte

• Add a reader and a writer for fixed-strings

  Users have now access to two new functions that enable to read and
  write fixed-length strings.

  bare.readFixedString(bc, /* string's length in bytes */ 4)
  bare.writeFixedString(bc, "bare")

• Simplification of ByteCursor

• BREAKING CHANGE: rename all decode/encode into read/write

  read/write feel more low-level than decode/encode.
  read/write are also more used among BARE implementations than decode/encode.
  Moreover, in JS, decode and encode are used for high-level API such as
  TextDEcoder and TextEncoder.

  bare.decodeU8(bc) // Previously
  bare.readU8(bc) // Now
  
  bare.encodeU8(bc, 42) // Previously
  bare.writeU8(bc, 42) // Now

• BREAKING CHANGE: length can no longer be specified for fixed-array writers

  Previously, you had to specify the length of the fixed-array to encode.
  If the given length was different of the actual array's length,
  then an assertion was thrown ("unmatched length").

  It is no longer possible to specify the length.
  As a consequence, the fixed-array writers can no longer assert the length.

  Fixed-array writers now have the same signature as other writers.

  bare.readerU8FixedArray(bc, Uint8Array.of(42, 24), 2) // Previously
  bare.writeU8FixedArray(bc, Uint8Array.of(42, 24)) // Now

  Note that fixed-array readers still require the specification of the
  length:

  bare.decodeU8FixedArray(bc, 2)

• BREAKING CHANGE: ByteCursor no longer accept ArrayBuffer

  new ByteCursor(new ArrayBuffer(5), config) // Now fails
  new ByteCursor(new Uint8Array(5), config) // Update to this

• BREAKING CHANGE: remove ByteCursor#write

  Use writeU8FixedArray instead:

  const bc = new ByteCursor(buffer, config)
  
  bc.write(buffer) // Previously
  bare.writeU8FixedArray(bc, buffer) // Now

v0.1.1

• Fix write offset when byteOffset > 0

  A ByteCursor may be instantiated with an array of bytes such that
  the array's byteOffset is greater than 0.
  The previous ByteCursor.write implementation did not take care of adding this byteOffset to the ByteCursor's offset.

  The following code no longer fail:

  const bytes = Uint8Array.of(42, 24).subarray(1)
  assert(bytes.byteOffset === 1)
  
  const bc = ByteCursor(bytes, ...)
  bc.write(Uint8Array.of(24))
  assert.deepEqual(Array.from(bytes), [42, 24]) // Previously failed

• Smaller CommonJS bundle

• Improve byte-length computation of small string

v0.1.0

• ByteCursor abstraction to read and write safely a buffer of bytes

• Enable to configure at runtime:

  • initial buffer length
  • maximum buffer length
  • thresholds (string length) for switching from custom to native UTF-8 decoders/encoders

• Decoders and encoders for basic types (bool, opaque data, floats, integers, typed arrays, UTF-8 string)
