# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog ](https://keepachangelog.com/en/1.0.0/ ),
and this project adheres
to [Semantic Versioning ](https://semver.org/spec/v2.0.0.html ).
## [3.0.0] - Unreleased
### Added
- Added a `Promise` -based interface.
- The JSDoc is now much more exhaustive.
- An auto-generated JSDoc file is generated: [API.md ](./API.md ).
- Added `Datastore#dropDatabaseAsync` and its callback equivalent.
### Changed
- The `Datastore#update` 's callback has its signature slightly changed. The
`upsert` flag is always defined either at `true` or `false` but not `null` nor
`undefined` , and `affectedDocuments` is `null` when none is given rather than
`undefined` (except when there is an error of course).
- In order to expose a `Promise` -based interface and to remove `async` from the dependencies, many internals have been either rewritten or removed:
- Datastore:
- `Datastore#getCandidates` replaced with `Datastore#_getCandidatesAsync` ;
- `Datastore#resetIndexes` replaced with `Datastore#_resetIndexes` ;
- `Datastore#addToIndexes` replaced with `Datastore#_addToIndexes` ;
- `Datastore#removeFromIndexes` replaced with `Datastore#_removeFromIndexes` ;
- `Datastore#updateIndexes` replaced with `Datastore#_updateIndexes` ;
- `Datastore#_insert` replaced with `Datastore#_insertAsync` ;
- `Datastore#_update` replaced with `Datastore#_updateAsync` ;
- `Datastore#_remove` replaced with `Datastore#_removeAsync` ;
- Persistence:
- `Persistence#loadDatabase` replaced with `Persistence#loadDatabaseAsync` ;
- `Persistence#persistCachedDatabase` replaced with `Persistence#persistCachedDatabaseAsync` ;
- `Persistence#persistNewState` replaced with `Persistence#persistNewStateAsync` ;
- `Persistence#treatRawStream` replaced with `Persistence#treatRawStreamAsync` ;
- `Persistence.ensureDirectoryExists` replaced with `Persistence#ensureDirectoryExistsAsync` ;
- Cursor:
- `Cursor#_exec` replaced with `Cursor#_execAsync` ;
- `Cursor#project` replaced with `Cursor#_project` ;
- `Cursor#execFn` has been renamed to `Cursor#mapFn` and no longer supports a callback in its signature, it must be a synchronous function.
- Executor: it has been rewritten entirely without the `async` library.
- `Executor#buffer` & `Executor#queue` do not have the same signatures as before;
- `Executor#push` replaced with `Executor#pushAsync` which is substantially different;
- Storage modules : callback-based functions have been replaced with promise-based functions.
- Model module: it has been slightly re-written for clarity, but no changes in its interface was made.
## Deprecated
- Using a `string` in the constructor of NeDB is now deprecated.
- Using `Datastore#persistence#compactDatafile` is now deprecated, please use `Datastore#compactDatafile` instead.
- Using `Datastore#persistence#setAutocompactionInterval` is now deprecated, please use `Datastore#setAutocompactionInterval` instead.
- Using `Datastore#persistence#stopAutocompaction` is now deprecated, please use `Datastore#stopAutocompaction` instead.
## Removed
- The option for passing `options.nodeWebkitAppName` to the Datastore and the Persistence constructors has been removed.
- `Persistence.getNWAppFilename` ;
## [2.2.0] - 2021-10-29
### Added
- Include a `"react-native"` version (heavily inspired from [react-native-local-mongdb ](https://github.com/antoniopresto/react-native-local-mongodb )).
## [2.1.0] - 2021-10-21
Thanks to [@eliot-akira ](https://github.com/eliot-akira ) for the amazing work on file streaming.
### Changed
- [implement file streaming of the database ](https://github.com/seald/nedb/pull/5 ) like [a PR on the original repo ](https://github.com/louischatriot/nedb/pull/463 ) did;
- internalize [`byline` ](https://github.com/jahewson/node-byline ) package because it is unmaintained.
- TypeScript typings inside the package.
## [2.0.4] - 2021-07-12
### Fixed
- switch back to an AVLTree instead of a BinarySearchTree like the original nedb to fix [#1 ](https://github.com/seald/nedb/issues/1 ).
- updated vulnerable dev dependency `ws`
## [2.0.3] - 2021-06-07
### Fixed
- no longer use `util` module for type verification as it is needed in the
browser, which would need a polyfill.
## [2.0.2] - 2021-05-26
### Fixed
- the `browser` field of the `package.json` no longer points to the bundled
minified version for the browser, but switches the `storage.js` and
`customUtils.js` to their browser version, just like the original repository
used to do.
## [2.0.1] - 2021-05-19
### Changed
- bump `@seald-io/binary-search-tree` to 1.0.2, which does not depend
on `underscore` ;
- replace use of `underscore` by pure JS.
## [2.0.0] - 2021-05-18
This version should be a drop-in replacement for `nedb@1.8.0` provided you use
modern browsers / versions of Node.js since ES6 features are now used (such
as `class` and `const` / `let` ).
### Changed
- Update `homepage` & `repository` fields in the `package.json`
- New maintainer [seald ](https://github.com/seald/ ) and new package
name [@seald-io/nedb ](https://www.npmjs.com/package/@seald-io/nedb );
- Added `lockfileVersion: 2` `package-lock.json` ;
- Modernized some of the code with ES6 features (`class`, `const` & `let` );
- Uses [`standard` ](https://standardjs.com/ ) to lint the code (which removes all
unnecessary semicolons);
- Updated dependencies, except `async` which stays at `0.2.10` for the moment;
- Stop including the browser version in the repository, and properly build it
with `webpack` ;
- Uses `karma` to run the browser tests, and use npm to fetch versioned
dependencies rather than having hardcoded copies of the dependencies in the
repository;
- Internalized `exec-time` dependency for the benchmarks, because it was
unmaintained;
- Uses `@seald-io/binary-search-tree` rather than
unmaintained `binary-search-tree` ;
### Removed
- Compatibility with old browsers and old version of Node.js that don't support
ES6 features.
- From now on, this package won't be published with `bower` as it became
essentially useless.
- Entries in the `browser` field of package.json don't include individual files,
only the bundled minified version, those files are still published with the
package.
### Security
- This version no longer
uses [a vulnerable version of `underscore` ](https://github.com/advisories/GHSA-cf4h-3jhx-xvhq )
.
