2.6.2 (2023-02-24)

🐛 Bug Fixes

• Convert std::string explicitly before c_str() (f098f79)

2.7.0 (2023-02-12)

New fastWrites prop

2.7.0 adds a new prop to the MMKV configuration that changes the behaviour of set calls.

• When fastWrites is set to true, MMKV does not overwrite previous values when calling set. This is faster, but uses more memory.
• When fastWrites is set to false, MMKV deletes the previous value before calling set. This makes sure the storage size is always as small as possible, with the added performance cost of one delete call before setting.

Before this version, MMKV behaved as if fastWrites was set to true (i.e.; fast, but use more memory). Now after this PR, fastWrites is false by default, because users were complaining in #440 that the storage size grows too big.

🐛 Bug Fixes

• Add codegenConfig to package.json (#506) (9965b34)

✨ Features

• Add fastWrites prop (#509) (c9788c7), closes #440

2.5.0 (2022-10-20)

✨ Features

• Support setting and getting ArrayBuffers (Uint8Array) (#460) (1f2bcd1), closes #463

Example:

const storage = new MMKV()

// Set to storage
const buffer = new Uint8Array([255, 100, 8, 5])
storage.set('someToken', buffer)

// Get from storage
const buffer = storage.getBuffer('someToken')
console.log(buffer) // [255, 100, 8, 5]

// Fun Fact:
// You can read every value as a Buffer:
storage.set('someString', 'Hey!');
const buffer = storage.getBuffer('someString')
console.log(buffer); // [72, 101, 121, 33]
