Overview

TypeScript definitions for nedb

Classes

class Nedb

class Nedb<G = any> extends EventEmitter {}

constructor

constructor(pathOrOptions?: string | Nedb.DataStoreOptions);

property persistence

persistence: Nedb.Persistence;

method addListener

addListener: (event: 'compaction.done', listener: () => void) => this;

method addToIndexes

addToIndexes: <T extends G>(doc: T | T[]) => void;

Add one or several document(s) to all indexes

method count

count: {
    (query: any, callback: (err: Error | null, n: number) => void): void;
    (query: any): Nedb.CursorCount;
};

Count all documents matching the query
Parameter query
MongoDB-style query

method ensureIndex

ensureIndex: (
    options: Nedb.EnsureIndexOptions,
    cb?: (err: Error | null) => void
) => void;

Ensure an index is kept for this field. Same parameters as lib/indexes For now this function is synchronous, we need to test how much time it takes We use an async API for consistency with the rest of the code
Parameter cb
Optional callback, signature: err

method find

find: {
    <T extends G>(
        query: any,
        projection: any,
        callback: (err: Error | null, documents: T[]) => void
    ): void;
    <T extends G>(query: any, projection?: any): Nedb.Cursor<T>;
    <T extends G>(
        query: any,
        callback: (err: Error, documents: T[]) => void
    ): void;
};

Find all documents matching the query If no callback is passed, we return the cursor so that user can limit, skip and finally exec
Parameter query
MongoDB-style query
Parameter projection
MongoDB-style projection
Find all documents matching the query If no callback is passed, we return the cursor so that user can limit, skip and finally exec *
Parameter query
MongoDB-style query

method findOne

findOne: {
    <T extends G>(
        query: any,
        projection: any,
        callback: (err: Error | null, document: T) => void
    ): void;
    <T extends G>(query: any, callback: (err: Error, document: T) => void): void;
};

Find one document matching the query
Parameter query
MongoDB-style query
Parameter projection
MongoDB-style projection
Find one document matching the query
Parameter query
MongoDB-style query

method getAllData

getAllData: () => any[];

Get an array of all the data in the database

method getCandidates

getCandidates: (query: any) => void;

Return the list of candidates for a given query Crude implementation for now, we return the candidates given by the first usable index if any We try the following query types, in this order: basic match, $in match, comparison match One way to make it better would be to enable the use of multiple indexes if the first usable index returns too much data. I may do it in the future.
TODO: needs to be moved to the Cursor module

method insert

insert: {
    <T extends G>(
        newDoc: T,
        cb?: (err: Error | null, document: T) => void
    ): void;
    <T extends G>(newDocs: T[], cb?: (err: Error, documents: T[]) => void): void;
};

Insert one or more new documents
Parameter cb
Optional callback, signature: err, insertedDoc

method listeners

listeners: (event: 'compaction.done') => Array<() => void>;

method loadDatabase

loadDatabase: (cb?: (err: Error | null) => void) => void;

Load the database from the datafile, and trigger the execution of buffered commands if any

method off

off: (event: 'compaction.done', listener: () => void) => this;

method on

on: (event: 'compaction.done', listener: () => void) => this;

method once

once: (event: 'compaction.done', listener: () => void) => this;

method prependListener

prependListener: (event: 'compaction.done', listener: () => void) => this;

method prependOnceListener

prependOnceListener: (event: 'compaction.done', listener: () => void) => this;

method rawListeners

rawListeners: (event: 'compaction.done') => Array<() => void>;

method remove

remove: {
    (
        query: any,
        options: Nedb.RemoveOptions,
        cb?: (err: Error | null, n: number) => void
    ): void;
    (query: any, cb?: (err: Error, n: number) => void): void;
};

Remove all docs matching the query For now very naive implementation (similar to update)
Parameter options
Optional options options.multi If true, can update multiple documents (defaults to false)
Parameter cb
Optional callback, signature: err, numRemoved
private Use Datastore.remove which has the same signature

method removeFromIndexes

removeFromIndexes: <T extends G>(doc: T | T[]) => void;

Remove one or several document(s) from all indexes

            upsert: boolean
        ) => void
    ): void;
};

Update all docs matching query v1.7.4 and prior signature. For now, very naive implementation (recalculating the whole database)
Parameter options
Optional options options.multi If true, can update multiple documents (defaults to false) options.upsert If true, document is inserted if the query doesn't match anything
Parameter cb
Optional callback, signature: err, numReplaced, upsert (set to true if the update was in fact an upsert)
private Use Datastore.update which has the same signature
Update all docs matching query v1.8 signature. For now, very naive implementation (recalculating the whole database)
Parameter options
Optional options options.multi If true, can update multiple documents (defaults to false) options.upsert If true, document is inserted if the query doesn't match anything
Parameter cb
Optional callback, signature: err, numAffected, affectedDocuments (when returnUpdatedDocs is set to true), obj or array upsert (set to true if the update was in fact an upsert)
private Use Datastore.update which has the same signature

method updateIndexes

    <T extends G>(oldDoc: T, newDoc: T): void;
    <T extends G>(updates: { oldDoc: T; newDoc: T }[]): void;
};

Update one or several documents in all indexes To update multiple documents, oldDoc must be an array of { oldDoc, newDoc } pairs If one update violates a constraint, all changes are rolled back
