node-pouch

Easily read/write data to multiple databases using PouchDB.

ToDo:

Allow deleting of records.

---

Usage:

var nodePouch = require("node-pouch");
var pouch = new nodePouch(name, base);

• name (optional): Database name/link.
• base (optional): Any base name like folder name to store the database inside that folder. Can be a link too in case of remote database.

Both arguments can be ignored if you want to specify full database name/link everytime in each function.

---

Methods: (All methods return promises with useful data & errors)

.get(id, name);

pouch.get(id, name);

• id: Unique record ID.
• name: Database name/link. Optional if already provided when creating a new instance of the module. Useful if you want to use a different database name/link.

Example:

pouch.get("unique-record-id");

---

.save(record, name);

pouch.save(record, name);

• record: A record object like: {_id: "unique-reqcord", name: "Apple", ...}. If _id is not provided, it will be randomly created for you.
• name: Database name/link. Optional if already provided when creating a new instance of the module. Useful if you want to use a different database name/link.

Example:

pouch.save({
  _id: "unique-record-id",
  name: "Apple",
  description: "Macbooks, iPads, iPhones"
  ...
});

If a record already exists with that _id, then it will be fetched first and all old record object values will also be included for incremental saving. For example, if a record had only name & decription earlier and you now want to save model also, then doing this will be sufficient and your old data will be preserved.

pouch.save({
  _id: "unique-record-id",
  model: "APPLE-001"
  ...
});

---

.index(fields, name)

pouch.index(fields, name);

Makes search faster if you use indexes.
Indexes are automatically created when you fetch record/records.

• fields: Fields to combine to make a search index.
• name: Database name/link. Optional if already provided when creating a new instance of the module. Useful if you want to use a different database name/link.

Example:

pouch.index(["name", "description']);

---

.record(keyOrObject, name)

pouch.record(keyOrObject, name);

• keyOrObject: Unique record ID or search object.
• name: Database name/link. Optional if already provided when creating a new instance of the module. Useful if you want to use a different database name/link.

pouch.record("unique-record-id");

Search indexes are created automatically if search is an object.

pouch.record({name: "Apple", model: "APPLE-001"});

---

.records(searchObject, name)

pouch.records(searchObject, name);

• searchObject: Same as the request object provided here: https://pouchdb.com/api.html#query_index
  If selector is not provided in searchObject, then it uses the searchObject itself as selector.
• name: Database name/link. Optional if already provided when creating a new instance of the module. Useful if you want to use a different database name/link.

pouch.records({name: "Apple", model: "APPLE-001"});

pouch.records({
  selector: {name: "Apple", model: "APPLE-001"},
  fields: ['_id', 'name'],
  sort: ['name']
});
