node-mongo-collections-loader v0.0.1
Node JS Mongodb collections loader
This library loads a Node.JS instance for each of your Mongodb schemas including an access object for each collection.
Then you can keep in memory those "Singleton" objects and use each one to access to each collection.
It uses Node.JS Mongodb native driver.
Install
npm install node-mongo-collections-loader
Usage
Import library
const {MongoCollectionsLoader} = require('node-mongo-collections-loader');
Define your schemas and your collections.
const instances = [
{
id: 'userSchema',
collections: [
'Users',
'Access'
],
},
{
id: 'myBusinessSchema',
collections: [
'Quotes',
'Orders',
],
},
];
Configure your Mongodb Auth object (Or retrieve it from secret)
{
userSchema: {
url: mongodb://myuserserver:27017?userSchema,
options: {
readPreference: 'secondaryPreferred'
},
},
myBusinessSchema: {
url: mongodb://mybusinessserver:27017?myBusinessSchema,
options: {
readPreference: 'secondaryPreferred'
},
},
}
Then, load collections (add an async
function if you are in a sync function)
... and you can use collections singletons with Mongodb native driver's Collection functions
(async () => {
const dao = await dao(app);
dao.userschema.Users.find(...)
dao.userSchema.Access.update(...)
dao.myBusinessSchema.Quotes.find(...)
})();
