pouchdb get all docs

(Most likely, if you are writing a PouchDB plugin, you will export either the 1.3.12. You can load plugins into PouchDB when you load it via require(). Delete an index, remove any orphaned design documents, and clean up any leftover data on disk. This is a convenience method for bidirectional data replication. PouchDB will always call your reduce function with rereduce == false. For instance, to PouchDB installation on Node. A better strategy is the “one database per user” method. If options.live is true, then this will track future changes and also replicate them automatically. Calling cancel() will unsubscribe all event listeners automatically. In the same way, if you fetch the contents of the local_database stored in PouchDB you can get to observe that documents of the database that is stored in CouchDB were copied here. See blob-util for utilities to transform Blobs to other formats, such as base64-encoded strings, data URLs, array buffers, etc. Warning: this runs client-side, if you are replicating from a remote database. There are also some details you can use for debugging. There is a new field, _rev, that contains what looks like garbage. Fetch multiple documents, indexed and sorted by the _id. You use the query() method to perform these reduce queries. This method creates a database or opens an existing one. ... PouchDB get documents by ID with certain string in them. However, it will always be supplied as base64. to revisions stored in the database. You can check out the code to get some inspiration: pouchService.js. /db/_all_docs?include_docs=true In PouchDB, it becomes. "R0lGODlhAQABAIAAAP7//wAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==", // replication paused (e.g. You should also prefer put() to post(), because when you post(), you are missing an opportunity to use allDocs() to sort documents by _id (because your _ids are random). a collection of name/value pairs. createIndex(), find(), listIndexes(), and deleteIndex(). As for CouchDB, refer to the. allDocs ({include_docs: true}) PouchDB enables applications to store data locally while … Do I have to use some options in the allDocs method like: db.allDocs({include_docs: true, deleted: true}) Thanks in advance. back a mixed array of errors/non-errors. This will add a db.methodName() to all databases, which runs myFunction.It will always be called in context, so that within the function, this refers to the database object. Both the source and target can be a PouchDB instance or a string representing a CouchDB database URL or the name of a local PouchDB database. The allDocs() method uses the automatic index that is created based on the values in the _id property of your documents. I am storing around 4000 documents into my pouchdb database. from the put()/post() API. For instance, to find all docs sorted by debut descending: Get a list of all the indexes you’ve created. Get an attachment with filename 'att.txt' from document with ID 'doc': Get an attachment with filename 'att.txt' from document with ID 'doc', at You can use this to load multiple plugins, add adapters, Replicate data from source to target. PouchDB create document. A useful feature of plugins is to intercept updates before they are stored in PouchDB. Post some new docs and auto-generate the _ids: The response contains an array of the familiar ok/rev/id Its value will either be push or pull. Also tells you about the If you try to store non-JSON data (for instance Date objects) you may see inconsistent results. The CouchDB documentation for map/reduce applies to PouchDB. If you have any questions or issues with the deployment, leaving a comment and we will work together to find a solution. As with changes(), you can also omit live, in which case you can use replicate() in the callback/promise style and it will be treated as a single-shot operation. and will fire the 'complete' event when the results are ready. I am new in pouchdb and I can't understand the API. Note that this 'complete' event only fires when you aren’t doing live changes. Once the data is added we’ll use the db.allDocs API to fetch the documents added to pouchdb. A list of changes made to documents in the database, in the order they were made. If you supply a string instead of a Blob/Buffer, then it will be assumed to be a base64-encoded string, and will be processed accordingly: You can also inline attachments inside the document. // All documents must have a .name field. PouchDB was created to help web developers build applications that work as well offline as they do online. you want on it. Currently we only have pouchb:api (API-level calls) and pouchdb:http (HTTP requests): These settings are saved to the browser’s LocalStorage. So now let's get() the document by using its _id: The document looks exactly the same as when we put it, except... aha! It does not behave, for example, like the Apache CouchDB validate_doc_update() API. This reduces the database’s size by removing unused and old data, namely non-leaf revisions and attachments that are no longer referenced by those revisions. If you’re dealing with large binary data (such as PNGs), you may incur a performance or storage penalty if you naïvely include them as base64- or hex-encoded strings inside your documents. In this way, a plugin might validate that the data is correct for the application, or even alter documents before they are committed to the database. Instead, set the doc._deleted flag to true and then use put() or bulkDocs(). (The _all_docs call can fetch a list of revisions, but currently can’t be told to include revision histories.)
