Microservices example code using Node.js, Redis, Hapi

Examples of building simple microservices using Node.js, Redis, and Hapi

Building simple Node.js microservices using Hapi and Redis - Nodevember 2015

Installation

Enter the directory of the example and npm install

redis-queue

An example of using a redis list as a queue for a microservice mail server. Microservice mail delivery processes can be spun up to listen to the queue and wait for work.

Another version done using a reliable queue where an additional list is used to track messages in transit. If a processes fails to deliver with in a specified amount of time, an item could be moved back to the original queue for delivery.

redis-cache

An example of using microservice(s) to prepopulate a redis list cache. An expensive computation like determining the next ads to display across campaigns could be done in advance by microservice workers and the results put into a cache queue for use. The microservice(s) can monitor the queue height and generate more when the count drops to a certain level.

hapi-api-gateway

Examples using hapi to build simple microservices and using hapi to build simple API proxies or smart API gateways. An API gateway can aggregate data from to many microservices into one call.

Hapi plugins are a nice mechanism for moving microservice funtionality between servers. By splitting off groups of functionality into plugins they can be used in a monolith application or easily moved into their own containers and servers.

wait-on

wait-on is a cross-platform command line utility and Node.js API which will wait for files, ports, sockets, and http(s) resources to become available

redux-logic

Redux middleware for organizing all your business logic. Intercept actions and perform async processing.

bench-rest

bench-rest - benchmark REST (HTTP/HTTPS) API's. node.js client module for easy load testing / benchmarking REST API's using a simple structure/DSL can create REST flows with setup and teardown and returns (measured) metrics.

joi-browser

joi validation bundled for the browser (deprecated) - use joi@16+

pkglink

Space saving Node.js package hard linker. pkglink locates common JavaScript/Node.js packages from your node_modules directories and hard links the package files so they share disk space.

autoflow

autoflow (formerly react) is a javascript module to make it easier to work with asynchronous code, by reducing boilerplate code and improving error and exception handling while allowing variable and task dependencies when defining flow.

redux-logic-test

redux-logic test utilities to facilitate the testing of logic. Create mock store

redis-rstream

redis-rstream is a node.js redis read stream which streams binary or utf8 data in chunks from a redis key using an existing redis client (streams2). Tested with mranney/node_redis client.

digest-stream

Simple node.js pass-through stream (RW) which calculates the a crypto digest (sha/md5 hash) of a stream and also the length. Pipe your stream through this to get digest and length. (streams2)

markdown-it-modify-token

markdown-it plugin for modifying tokens in a markdown document. It can for example modify content or attributes for certain type of elements like links or images.

redis-wstream

redis-wstream is a node.js redis write stream which streams binary or utf8 data into a redis key using an existing redis client (streams2). Tested with mranney/node_redis client.

pass-stream

pass-stream - pass-through node.js stream which can filter/adapt and pause data

base-react-min

Minimal React.js boilerplate with an auto build environment

ensure-array

Ensure that a javascript object is an array, coerce if necessary. Move error checking out of your node.js javascript code.

autoflow-graphviz

autflow-graphviz is a plugin for autflow, the flow control rules engine, which allows react to use graphviz to generate flow diagrams for the dependencies

accum

Simple stream sink which accumulates or collects the data from a stream. Pipe your stream into this to get all the data as buffer, string, or raw array. (streams2)

hapi-bunyan-lite

Minimalistic Bunyan logging integration for Hapi - forwards Hapi log events to bunyan

ngzip

ngzip is a portable streaming stdio gzip command line utility that uses Node.js zlib. It should run anywhere Node.js runs including windows, *nix, mac.

tapper

Tapper (tapr) is a node.js tap runner which improves formatting and allows stdout and stderr mixed in with the tap output. Also optionally adds color to the output

joi-full

joi object schema validation with extensions as universal/isomorphic libarary for Node.js and bundled for the browser (babelified and bundled)

autoflow-deferred

autoflow-deferred is a plugin for react, the flow control rules engine, which adds integration with jQuery-style Deferred promises

jsconf-react

length-stream

Simple pass-through node.js stream (RW) which accumulates the length of the stream. (streams2)

git-clone-init

Create new project from clone - clone repo, rm .git, git init, sed files, git commit

autoflow-q

autoflow-q is a plugin for autoflow, the flow control rules engine, which adds integration with Q-style Deferred promises https://github.com/kriskowal/q
