Probably not. CouchDB is accessed through a REST API.
For instance, to What standards does the webservice need to adhere to to be compatible with couchdb/pouchdb? It needs to implement the CouchDB Replication protocol. Use PouchDB's sequences and checkpoints to sync to something that's not CouchDB Please see that repo for documentation, tests, and code.. This behaves the same as PouchDB.sync(): db.
A PouchDB plug-in that allows you to re-use your CouchDB validate_doc_update functions on the client side.
Consult the Given a set of document/revision IDs, returns the subset of those that do not correspond References. )You can load plugins into PouchDB when you load it via A useful feature of plugins is to intercept updates before they are stored in PouchDB. So if you are using closures, then you must use the slower method that requires a full database scan.As design docs are deleted or modified, their associated index files (in CouchDB) or companion databases (in local PouchDBs) continue to take up space on disk.
replication up to date, user went offline)// replicate resumed (e.g. It handles authentication for you during those REST calls which prevents unauthorized access. This is a plugin that lets you use CouchDBs replication algorithm with checkpointing, resuming, etc, but provide your own function to write the documents.
The downside to this approach is that we lose the ability to automatically sync between the local PouchDB database and the remote CouchDB database, it would just be a normal REST API now with no fancy replication or offline syncing happening. Read the changes feed from the PouchDB, …
If the sync promise resolves, write a checkpoint of the last sequence numbers from the written batch
By default, PouchDB ships with the PouchDB attempts to provide a consistent API that "just works" across every browser and JavaScript environment, and in most cases, you can just use the defaults.
– but it will be deleted as soon as the user closes their browser.
If you want to trigger a server-initiated replication, please use regular ajax to POST to the CouchDB If you are replicating from a remote CouchDB, then the first method will run client-side, whereas the last four will filter on the server side. The Mango API is just a simplified user-facing API on top of map/reduce.Note that closures are only supported by local databases with temporary views. If your database lives under `/couchdb`, then it would be accessed through `/couchdb/database1`.
The sync function should return a promise that fails if the write failed.If the sync promise resolves, write a checkpoint of the last sequence numbers from the written batchA document is only sent to the sync function once per sync cycle.
To create a database simply instantiate a new PouchDB object with the name of the database: // EDITING STARTS HERE (you dont need to edit anything above this line) var db = new PouchDB ('todos'); var remoteCouch = false; For instance, to find all docs sorted by Get a list of all the indexes youâve created.
The attachment data may be supplied as a base64-encoded string with the The inline approach allows you to save multiple attachments to the same document in a single shot:This âsummaryâ operation may be faster in some cases, because the attachment itself does not need to be read from disk.Delete an attachment from a doc. It also supports an --in-memory mode and any LevelDOWN adapter, which you may find handy. To use a custom promise implementation with PouchDB, you must redefine a global This method creates a database or opens an existing one. special Delete an index, remove any orphaned design documents, and clean up any leftover data on disk.Note that the easiest way to do this is to locate the index you want to delete using Invoke a map/reduce function, which allows you to perform more complex queries on PouchDB than what you get with Since views perform a full scan of all documents, this method may be slow, unless you first save your view in a design document. new changes replicating, user went back online)// a document failed to replicate (e.g.
require native or preloaded access to the database files, or there's some other reason to go native.
object-style or the function-style plugin, so that your users can then Take a look at this quote from PouchDb documentation: CouchDB was designed with sync in mind, and this is exactly what it excels at. It returns an object with the method In these examples, weâll work with some mammals. Sync Gateway is a secure web gateway application with synchronization, REST, stream, batch and event APIs for accessing and synchronizing data over the web. When your PouchDB application starts up it could perform a one-off, one-way replication to completion and then initiate the two-way, continuous retryable sync:The above technique results in fewer HTTP requests being used and better performance than just using This method will update an existing document to add the attachment, so it requires a Whatâs the point of attachments? Note that this is a separate operation from For remote databases, PouchDB checks the compaction status at regular intervals and fires the callback (or resolves the promise) upon completion. There are also some details you can use for debugging.
To install Sync Gateway, However, if you're trying to reach the widest possible audience, or if you want the best performance, then you will sometimes want to tinker with the adapter settings.If you're ever curious which adapter is being used in a particular browser, you can use the following method:On Cordova/PhoneGap/Ionic, the native SQLite database is often a popular choice, because it allows unlimited storage (compared to There are various Cordova plugins that can provide access to native SQLite, such as Read the changes feed from the PouchDB, limiting the number of changes to batch_size. This can be used to sequentially write updates to a REST API,A function which you use for writing whatever you need to write the documents to.
