How to Set Up a MEAN Stack with Nx in Less than 20 Minutes

20 minutes, 3 steps, 1 running JavaScript full-stack TODO app! Let’s do this! 😎

When starting a new project, there is always a bunch of annoying, time-consuming tasks required to set up your app, install the tools, go through the doc, remember the shell commands… 😩.

I’ve personally started dozens of apps and every time, it’s the same thing all over again. The worst part is that I never remember the process by heart and feel like wasting my time because it’s literally identical.

So, for this article (and my mental health ✌️), I’ve decided to build and share with you the “groundwork” for a MEAN stack app, using Nx. Just as a quick reminder, MEAN — means (sorry I had to… 😂) — stands for  MongoDB,  Express,  Angular &  Node.js.

Nx is a tool meant to build, architect, and test a monorepo (several apps in one single codebase). After the setup, we will implement a simple end-to-end TODO app.

Prerequisites

There are two prerequisites, being the installation of NodeJS and MongoDB. We’ll focus on the app more than the installation. You can download NodeJS here and MongoDB  here.

My setup

node -v
//  v12.20.0

npm -v
// v6.14.8
mongo --version
// MongoDB shell version v4.2.3

Ready, get set…

#nodejs #angular #javascript #programming

A Simple Wrapper Around Amplify AppSync Simulator

This serverless plugin is a wrapper for amplify-appsync-simulator made for testing AppSync APIs built with serverless-appsync-plugin.

Install

npm install serverless-appsync-simulator
# or
yarn add serverless-appsync-simulator

Usage

This plugin relies on your serverless yml file and on the serverless-offline plugin.

plugins:
  - serverless-dynamodb-local # only if you need dynamodb resolvers and you don't have an external dynamodb
  - serverless-appsync-simulator
  - serverless-offline

Note: Order is important serverless-appsync-simulator must go before serverless-offline

To start the simulator, run the following command:

sls offline start

You should see in the logs something like:

...
Serverless: AppSync endpoint: http://localhost:20002/graphql
Serverless: GraphiQl: http://localhost:20002
...

Configuration

Put options under custom.appsync-simulator in your serverless.yml file

| option | default | description | | ------------------------ | -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | | apiKey | 0123456789 | When using API_KEY as authentication type, the key to authenticate to the endpoint. | | port | 20002 | AppSync operations port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20002, 20012, 20022, etc.) | | wsPort | 20003 | AppSync subscriptions port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20003, 20013, 20023, etc.) | | location | . (base directory) | Location of the lambda functions handlers. | | refMap | {} | A mapping of resource resolutions for the Ref function | | getAttMap | {} | A mapping of resource resolutions for the GetAtt function | | importValueMap | {} | A mapping of resource resolutions for the ImportValue function | | functions | {} | A mapping of external functions for providing invoke url for external fucntions | | dynamoDb.endpoint | http://localhost:8000 | Dynamodb endpoint. Specify it if you're not using serverless-dynamodb-local. Otherwise, port is taken from dynamodb-local conf | | dynamoDb.region | localhost | Dynamodb region. Specify it if you're connecting to a remote Dynamodb intance. | | dynamoDb.accessKeyId | DEFAULT_ACCESS_KEY | AWS Access Key ID to access DynamoDB | | dynamoDb.secretAccessKey | DEFAULT_SECRET | AWS Secret Key to access DynamoDB | | dynamoDb.sessionToken | DEFAULT_ACCESS_TOKEEN | AWS Session Token to access DynamoDB, only if you have temporary security credentials configured on AWS | | dynamoDb.* | | You can add every configuration accepted by DynamoDB SDK | | rds.dbName | | Name of the database | | rds.dbHost | | Database host | | rds.dbDialect | | Database dialect. Possible values (mysql | postgres) | | rds.dbUsername | | Database username | | rds.dbPassword | | Database password | | rds.dbPort | | Database port | | watch | - *.graphql
- *.vtl | Array of glob patterns to watch for hot-reloading. |

Example:

custom:
  appsync-simulator:
    location: '.webpack/service' # use webpack build directory
    dynamoDb:
      endpoint: 'http://my-custom-dynamo:8000'

Hot-reloading

By default, the simulator will hot-relad when changes to *.graphql or *.vtl files are detected. Changes to *.yml files are not supported (yet? - this is a Serverless Framework limitation). You will need to restart the simulator each time you change yml files.

Hot-reloading relies on watchman. Make sure it is installed on your system.

You can change the files being watched with the watch option, which is then passed to watchman as the match expression.

e.g.

custom:
  appsync-simulator:
    watch:
      - ["match", "handlers/**/*.vtl", "wholename"] # => array is interpreted as the literal match expression
      - "*.graphql"                                 # => string like this is equivalent to `["match", "*.graphql"]`

Or you can opt-out by leaving an empty array or set the option to false

Note: Functions should not require hot-reloading, unless you are using a transpiler or a bundler (such as webpack, babel or typescript), un which case you should delegate hot-reloading to that instead.

Resource CloudFormation functions resolution

This plugin supports some resources resolution from the Ref, Fn::GetAtt and Fn::ImportValue functions in your yaml file. It also supports some other Cfn functions such as Fn::Join, Fb::Sub, etc.

Note: Under the hood, this features relies on the cfn-resolver-lib package. For more info on supported cfn functions, refer to the documentation

Basic usage

You can reference resources in your functions' environment variables (that will be accessible from your lambda functions) or datasource definitions. The plugin will automatically resolve them for you.

provider:
  environment:
    BUCKET_NAME:
      Ref: MyBucket # resolves to `my-bucket-name`

resources:
  Resources:
    MyDbTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: myTable
      ...
    MyBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: my-bucket-name
    ...

# in your appsync config
dataSources:
  - type: AMAZON_DYNAMODB
    name: dynamosource
    config:
      tableName:
        Ref: MyDbTable # resolves to `myTable`

Override (or mock) values

Sometimes, some references cannot be resolved, as they come from an Output from Cloudformation; or you might want to use mocked values in your local environment.

In those cases, you can define (or override) those values using the refMap, getAttMap and importValueMap options.

  • refMap takes a mapping of resource name to value pairs
  • getAttMap takes a mapping of resource name to attribute/values pairs
  • importValueMap takes a mapping of import name to values pairs

Example:

custom:
  appsync-simulator:
    refMap:
      # Override `MyDbTable` resolution from the previous example.
      MyDbTable: 'mock-myTable'
    getAttMap:
      # define ElasticSearchInstance DomainName
      ElasticSearchInstance:
        DomainEndpoint: 'localhost:9200'
    importValueMap:
      other-service-api-url: 'https://other.api.url.com/graphql'

# in your appsync config
dataSources:
  - type: AMAZON_ELASTICSEARCH
    name: elasticsource
    config:
      # endpoint resolves as 'http://localhost:9200'
      endpoint:
        Fn::Join:
          - ''
          - - https://
            - Fn::GetAtt:
                - ElasticSearchInstance
                - DomainEndpoint

Key-value mock notation

In some special cases you will need to use key-value mock nottation. Good example can be case when you need to include serverless stage value (${self:provider.stage}) in the import name.

This notation can be used with all mocks - refMap, getAttMap and importValueMap

provider:
  environment:
    FINISH_ACTIVITY_FUNCTION_ARN:
      Fn::ImportValue: other-service-api-${self:provider.stage}-url

custom:
  serverless-appsync-simulator:
    importValueMap:
      - key: other-service-api-${self:provider.stage}-url
        value: 'https://other.api.url.com/graphql'

Limitations

This plugin only tries to resolve the following parts of the yml tree:

  • provider.environment
  • functions[*].environment
  • custom.appSync

If you have the need of resolving others, feel free to open an issue and explain your use case.

For now, the supported resources to be automatically resovled by Ref: are:

  • DynamoDb tables
  • S3 Buckets

Feel free to open a PR or an issue to extend them as well.

External functions

When a function is not defined withing the current serverless file you can still call it by providing an invoke url which should point to a REST method. Make sure you specify "get" or "post" for the method. Default is "get", but you probably want "post".

custom:
  appsync-simulator:
    functions:
      addUser:
        url: http://localhost:3016/2015-03-31/functions/addUser/invocations
        method: post
      addPost:
        url: https://jsonplaceholder.typicode.com/posts
        method: post

Supported Resolver types

This plugin supports resolvers implemented by amplify-appsync-simulator, as well as custom resolvers.

From Aws Amplify:

  • NONE
  • AWS_LAMBDA
  • AMAZON_DYNAMODB
  • PIPELINE

Implemented by this plugin

  • AMAZON_ELASTIC_SEARCH
  • HTTP

Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Online angular editor for building demo.

Let me show what I mean…

What is the Difference between Full Stack and Mean Stack Developer

A MEAN Stack Developer is a professional who has the knowledge and experience in certain areas as it were. In contrast with Full Stack Developer, a Mean Stack Developer uses a blend of MongoDB databases and front-end technology like ExpressJS, AngularJS, and  NodeJS to make a full-stack application. This is what is the basic difference between the full stack and mean stack developer and the present blog will deep dive in to further details that will clearly compare full-stack versus mean stack development in the forthcoming segments

What is Full Stack? What’s more, for what reason do you need Full stack?

Full-stack development is considered as one of the pursued and in demand in the software business as it is inclusive of both front-end and back-end technologies like Python, Ruby, Java, PHP, J2EE, C#, Perl, etc. A full-stack web developer is proficient in varied technologies and is generally looked out by varied associations as their team leads for bigger projects.

Front End of a Full Stack

In the present-day technological scenario, front-end technologies are becoming very prevalent in terms of product and project development. A project or product is deemed to be successful when the customer interface is positive. Such a circumstance happens when the front-end technology implemented in its best version. In this way a full stack web developer needs to master some of the basic front end technologies namely

  • HTML5,
  • CSS3,
  • JavaScript,

and furthermore be aware of outsider libraries, for example,

  • JQuery,
  • LESS,
  • SASS,
  • AngularJS,
  • React JS etc

Back End of a Full Stack

A full-stack developer uses the back-end technologies to administer and manage the processes carried out by the database. It is used for giving user authentication and to set up the website content.  As a full-stack web developer one needs to be proficient in a few back end languages, for example,

  • Node JS,
  • PHP,
  • Python etc.

A web application isn’t complete without the back-end support.

Prerequisites For Becoming a Full Stack Developer

The “prerequisites for becoming a Full Stack Developer are few and they are listed below”:

  1. If you compare full-stack versus mean stack developers, a Full Stack Developer needs to be proficient in varied programming languages than mean stack developers. They should be acceptable in languages ( yet not all) like Python, C#, Ruby, Java, Ruby, PHP, Perl, etc. Most of the business processes are written in either of these languages.
  2. Along with programming languages, great development frameworks are to be learned like MyBatis, Hibernate, JAVA Spring, PHP thinkplp, node JS, etc.
  3. Implementation of front-end technologies is additionally essential so as a Full-Stack Developer, one needs to learn the front-end technologies like JavaScript, CSS3 alongside learning the front-end frameworks like REACT, Angular JS, JQuery, LESS.
  4. As a Full Stack Developer, one needs to think about mainstream databases like MySQL, MongoDB, Redis, Oracle, SQL Server, etc.
  5. A Full Stack Developer ought to likewise know the principle basic prototype designs like UI, UX as well
  6. Finally, a Full Stack Developer ought to possess creativity, interest, great relational abilities, time management abilities, and worldwide speculation to reach higher objectives in this job.

What is Mean Stack? Furthermore, why you need Mean Stack?

Mean Stack is a technology stack that is a blend of JavaScript-based technologies that are being used for developing web-based applications. MEAN represents MongoDB, ExpressJS, AngularJS, and NodeJS. If you compare mean stack versus python, MEAN Stack is a fully working Full Stack JavaScript whereas Python is only a simple programming language.

Mean Stack can be defined as follows: M represents Mongo DB, which is a NoSQL database system E represents Express JS framework which used for building Node-based web application A represents Angular JS which is a Google-developed JavaScript framework. N represents Node JS which is a JavaScript bases execution environment.

Front End of a Mean Stack developer

The Front end application of MEAN Stack is created utilizing Angular JS which is an open-source JavaScript framework maintained by Google. In the present day of Jack of all trade that is Full-Stack versus MEAN, Full Stack seems to be versatile yet MEAN Stack is simple and easy to learn. Rakish JS uses HTML as its template language supporting a smarter web-based application.

Back End of a Mean Stack developer

MEAN  Stack web development uses Node JS as its Back end technology including modules called Mongoose which goes about as the Mongo DB object modeling and leads to the website application framework utilizing ExpressJS. Node JS is swift and as compared to other back-end environments.
