meseret-utils

A collection of handy utility functions and middleware compatible with meseret.

Getting Started

To install, inside a meseret project:

yarn add meseret-utils
 
# or, using npm: 
# npm i meseret-utils --save 

Then, we'll need to run the configuration/setup function (called configureMeseretUtils) at our app's entry like:

// maybe, your index.ts
 
import { ServerApp } from 'meseret'
import { configureMeseretUtils } from 'meseret-utils'
 
import { serverAppConfig } from './path/to/your/server-app-config'
 
export const serverApp = new ServerApp(serverAppConfig)
 
configureMeseretUtils({
  serverApp 
})
 
serverApp.start().catch(console.error)

Utils

Helper Functions

• C.R.U.D.: a collection of functions (add, get, list, search, edit and remove) that perform read and write operations on MongoDB collections (as modelled by mongoose); these functions include extensive error handling, and highly customizable querying and action plugging.

• email: an easy way to send an email.

• Grid: a nice abstraction of GridFS, the large-file-size-capable storage system inside MongoDB.

• KoaController: a controller super-class that works hand-in-hand with our handle middleware.

• KoaError: an extension of Error (with support for error code and HTTP status) that is compatible with koa and our handle middleware.

• password: a pair of functions that assist in an account's password reset process.

• PhotoGrid: coming soon, in the next few feature releases.

• transact: an abstraction to quickly support MongoDB's session-based multi-document ACID-compatible transactions; these require MongoDB 4+.

Koa Middleware

• authenticate: handles account authentication checks using koa-passport and responds to errors graciously.

• authorize: handles authorization by account roles, after implicitly calling our authenticate middleware.

• handle: a koa middleware that implicitly calls our transact function on our koa-controller methods and nicely handles our koa-error throws.

• login: a helper koa middleware to quickly login to an account using koa-passport.

• logout: a helper koa middleware to quickly logout from an account.

• sslRedirect: a koa middleware that redirects all HTTP requests to HTTPS in "production" environments (unless other environments are passed to it).

Mongoose Models

• KeyModel: a mongoose data model used in our password reset functions to store unique keys (tokens).

Types

• ObjectId: a shortcut for the type mongoose.Schema.Types.ObjectId | string.
