Fastify provides an 4 | easy path to a microservice architecture, in the future you might want 5 | to independently deploy some of those. 6 | 7 | In this folder you should define all the services that define the routes 8 | of your web application. 9 | Each service is a [Fastify 10 | plugin](https://www.fastify.io/docs/latest/Plugins/), it is 11 | encapsulated (it can have its own independent plugins) and it is 12 | typically stored in a file; be careful to group your routes logically, 13 | e.g. all `/users` routes in a `users.js` file. We have added 14 | a `root.js` file for you with a '/' root added. 15 | 16 | If a single file become too large, create a folder and add a `index.js` file there: 17 | this file must be a Fastify plugin, and it will be loaded automatically 18 | by the application. You can now add as many files as you want inside that folder. 19 | In this way you can create complex services within a single monolith, 20 | and eventually extract them. 21 | 22 | If you need to share functionality between services, place that 23 | functionality into the `plugins` folder, and share it via 24 | [decorators](https://www.fastify.io/docs/latest/Decorators/). 25 |

They can define decorators and set hooks 10 | that will then be used in the rest of your application. 11 | 12 | Check out: 13 | 14 | * [The hitchhiker's guide to plugins](https://www.fastify.io/docs/latest/Plugins-Guide/) 15 | * [Fastify decorators](https://www.fastify.io/docs/latest/Decorators/). 16 | * [Fastify lifecycle](https://www.fastify.io/docs/latest/Lifecycle/). 17 | -------------------------------------------------------------------------------- /Chapter11/fastify-microservice/plugins/support.js: -------------------------------------------------------------------------------- 1 | 'use strict' 2 | 3 | const fp = require('fastify-plugin') 4 | 5 | // the use of fastify-plugin is required to be able 6 | // to export the decorators to the outer scope 7 | 8 | module.exports = fp(async function (fastify, opts) { 9 | fastify.decorate('someSupport', function () { 10 | return 'hugs' 11 | }) 12 | }) 13 | -------------------------------------------------------------------------------- /Chapter11/fastify-microservice/routes/README.md: -------------------------------------------------------------------------------- 1 | # Services Folder 2 | 3 | Services define routes within your application. Fastify provides an 4 | easy path to a microservice architecture, in the future you might want 5 | to independently deploy some of those. 6 | 7 | In this folder you should define all the services that define the routes 8 | of your web application. 9 | Each service is a [Fastify 10 | plugin](https://www.fastify.io/docs/latest/Plugins/), it is 11 | encapsulated (it can have its own independent plugins) and it is 12 | typically stored in a file; be careful to group your routes logically, 13 | e.g. all `/users` routes in a `users.js` file. We have added 14 | a `root.js` file for you with a '/' root added. 15 | 16 | If a single file become too large, create a folder and add a `index.js` file there: 17 | this file must be a Fastify plugin, and it will be loaded automatically 18 | by the application. You can now add as many files as you want inside that folder. 19 | In this way you can create complex services within a single monolith, 20 | and eventually extract them. 21 | 22 | If you need to share functionality between services, place that 23 | functionality into the `plugins` folder, and share it via 24 | [decorators](https://www.fastify.io/docs/latest/Decorators/). 25 | 26 | If you're a bit confused about using `async/await` to write services, you would 27 | better take a look at [Promise resolution](https://www.fastify.io/docs/latest/Routes/#promise-resolution) for more details. 28

-------------------------------------------------------------------------------- 1 | # Developer's Guide 2 | 3 | We use Visual Studio Code for developing LoopBack and recommend the same to our 4 | users. 5 | 6 | ## VSCode setup 7 | 8 | Install the following extensions: 9 | 10 | - [eslint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) 11 | - [prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) 12 | 13 | ## Development workflow 14 | 15 | ### Visual Studio Code 16 | 17 | 1. Start the build task (Cmd+Shift+B) to run TypeScript compiler in the 18 | background, watching and recompiling files as you change them. Compilation 19 | errors will be shown in the VSCode's "PROBLEMS" window. 20 | 21 | 2. Execute "Run Rest Task" from the Command Palette (Cmd+Shift+P) to re-run the 22 | test suite and lint the code for both programming and style errors. Linting 23 | errors will be shown in VSCode's "PROBLEMS" window. Failed tests are printed 24 | to terminal output only. 25 | 26 | ### Other editors/IDEs 27 | 28 | 1. Open a new terminal window/tab and start the continuous build process via 29 | `npm run build:watch`. It will run TypeScript compiler in watch mode, 30 | recompiling files as you change them. Any compilation errors will be printed 31 | to the terminal. 32 | 33 | 2. In your main terminal window/tab, run `npm run test:dev` to re-run the test 34 | suite and lint the code for both programming and style errors. You should run 35 | this command manually whenever you have new changes to test. Test failures 36 | and linter errors will be printed to the terminal. 37 | -------------------------------------------------------------------------------- /Chapter11/loopback-bookstore/Dockerfile: -------------------------------------------------------------------------------- 1 | # Check out https://hub.docker.com/_/node to select a new base image 2 | FROM node:10-slim 3 | 4 | # Set to a non-root built-in user `node` 5 | USER node 6 | 7 | # Create app directory (with user `node`) 8 | RUN mkdir -p /home/node/app 9 | 10 | WORKDIR /home/node/app 11 | 12 | # Install app dependencies 13 | # A wildcard is used to ensure both package.json AND package-lock.json are copied 14 | # where available (npm@5+) 15 | COPY --chown=node package*.json ./ 16 | 17 | RUN npm install 18 | 19 | # Bundle app source code 20 | COPY --chown=node . . 21 | 22 | RUN npm run build 23 | 24 | # Bind to all network interfaces so that it can be mapped to the host OS 25 | ENV HOST=0.0.0.0 PORT=3000 26 | 27 | EXPOSE ${PORT} 28 | CMD [ "node", "." ] 29 | -------------------------------------------------------------------------------- /Chapter11/loopback-bookstore/README.md: -------------------------------------------------------------------------------- 1 | # loopback-bookstore 2 | 3 | [![LoopBack](https://github.com/strongloop/loopback-next/raw/master/docs/site/imgs/branding/Powered-by-LoopBack-Badge-(blue)-@2x.png)](http://loopback.io/) 4 | -------------------------------------------------------------------------------- /Chapter11/loopback-bookstore/src/__tests__/README.md: -------------------------------------------------------------------------------- 1 | # Tests 2 | 3 | Please place your tests in this folder. 4 | -------------------------------------------------------------------------------- /Chapter11/loopback-bookstore/src/__tests__/acceptance/home-page.acceptance.ts: -------------------------------------------------------------------------------- 1 | import {Client} from '@loopback/testlab';
