A dead-simple promise wrapper for nedb.
Check out the docs.
const Datastore = require('nedb-promises')
let datastore = Datastore.create('/path/to/db.db')
// #1
datastore.find({ field: true })
.then(...)
.catch(...)
// #2
datastore.find({ field: true })
.exec(...)
.then(...)
.catch(...)
// #1 and #2 are equivalent
datastore.findOne({ field: true })
.then(...)
.catch(...)
datastore.insert({ doc: 'yourdoc' })
.then(...)
.catch(...)
// or in an async function
async function findSorted(page, perPage = 10) {
return await datastore.find(...)
.sort(...)
.limit(perPage)
.skip(page * perPage)
}npm install --save nedb-promisesEverything works as the original module, with four major exceptions.
- There are no callbacks.
loadDatabasehas been renamed toload.- You should call
Datastore.create(...)instead ofnew Datastore(...). This way you can access the original nedb properties, such asdatastore.persistence. - As of v2.0.0 the module supports events 😎... Check out the docs about events!
Check out the original docs!
You don't need to call this as the module will automatically detect if the datastore has been loaded or not upon calling any other method.
const Datastore = require('nedb-promises')
let datastore = Datastore.create('/path/to/db.db')
datastore.load(...)
.then(...)
.catch(...)These methods will return a Cursor object that works the same way it did before except when you call "exec" it takes no arguments and returns a Promise.
The cool thing about this implementation of the Cursor is that it behaves like a Promise. Meaning that you can await it and you can call .then() on it.
const Datastore = require('nedb-promises')
let datastore = Datastore.create('/path/to/db.db')
//outside Promise chain
datastore.find(...)
.then(...)
.catch(...)
//insinde Promise chain
datastore.insert(...)
.then(() => {
return datastore.find(...)
})
.then(
// use the retrieved documents
)
;(async () => {
await datastore.find(...).sort(...).limit()
})()All the other methods will take the same arguments as they did before (except the callback) and will return a Promise.
