node.js - Is there a way to list collections with mongoskin?

Question

I already have an established database connection. I need to list the names of the collections in the database. Is it possible?

Answer 1

db.collectionNames(function(err, collectionArrayResult) {
    //Now do something with collectionArrayResult
});

结果是具有“名称”属性的对象数组，如下所示：

[
   { name: '<dbName>.<collectionName>' },
   ...
]

不过要小心 - <dbName>.system.indexes也会被退回。

Answer 2

要将集合从 mongo shell 显示到数据库中：

db.getCollectionNames()

因此，要在 mongoskin 中展示收藏，请尝试

var collections = db.collections();
collections.each(function(err, collection) {
    console.log(collection);
});
