[4.0.0] - 2023-01-19

Added

• [BREAKING] Implement compound indexes #27. Commas (,) can no longer be used in indexed field names.

Updated

• Updated @seald-io/binary-search-tree to v1.0.3.
• Updated dev dependencies, including standard@17.0.0 which changed some linting rules.
• Updated API docs.

Changed

• No longer execute test-typings.ts to check typings, just compile it.

[3.1.0] - 2022-09-02

Added

• Added a testSerializationHooks option which defaults to true. Setting to false allows to skip the test of the hooks, which may be slow.

[3.0.0] - 2022-03-16

Added

• Added a Promise-based interface.
• The JSDoc is now much more exhaustive.
• An auto-generated JSDoc file is generated: API.md.
• Added Datastore#dropDatabaseAsync and its callback equivalent.
• The Error given when the Datastore#corruptAlertThreshold is reached now has three properties: dataLength which is the amount of lines in the database file (excluding empty lines), corruptItems which is the amount of corrupted lines, corruptionRate which the rate of corruption between 0 and 1.
• Added a modes: { fileMode, dirMode } option to the Datastore which allows to set the file and / or directory modes, by default, it uses 0o644 for files and 0o755 for directories, which may be breaking.

Changed

• The corruptionAlertThreshold now doesn't take into account empty lines, and the error message is slightly 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 asynclibrary.
    • 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 were made.
• Typings were updated accordingly.

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, subsequently, the static method Persistence.getNWAppFilename has been removed as well;
• Compatibility with node < 10.1.0 (we use fs.promises).

Fixed

• [cherry picked from 2.2.2] #21 Typings for loadDatabase now support a callback.

[2.2.2] - 2022-03-10

Fixed

• #21 Typings for loadDatabase now support a callback.

[2.2.1] - 2022-01-18

Changed

• #20 storage.js: check fsync capability from return code rather than using process.platform heuristics (Thanks @bitmeal).

[2.2.0] - 2021-10-29

Added

• Include a "react-native" version (heavily inspired from react-native-local-mongdb).

Changed

• The browser version uses browser-version/lib/storage.browser.js instead of browser-version/lib/storage.js in the "browser" field of the package.json.

[2.1.0] - 2021-10-21

Thanks to @eliot-akira for the amazing work on file streaming.

Changed

• implement file streaming of the database like a PR on the original repo did;
• internalize 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.
• 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 and new package name @seald-io/nedb;
• Added lockfileVersion: 2 package-lock.json;
• Modernized some of the code with ES6 features (class, const & let);
• Uses standard 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 .

[1.8.0] - 2016-02-15
