Simple node js server API

A simple node.js server with routes and an API

Initial setup

https://www.freecodecamp.org/news/building-a-simple-node-js-api-in-under-30-minutes-a07ea9e390d2/

Instead of npm init I used the following (the first one creates package.json):

will@zen npm i typescript --save-dev

will@zen myserver % npx tsc --init

Created a new tsconfig.json with:
                                                                            TS
"compilerOptions": {
    "target": "es2016",
    "module": "es2015",
    "outDir": "./build",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "skipLibCheck": true  ,
    "moduleResolution":"node"
}

will@zen myserver %

Note: All commands below are executed from the following pwd:

will@zen myserver % pwd
/Users/will/dev/repos_github_mine/myserver

By invoking tsc with no input files, in which case the compiler searches for the tsconfig.json When input files are specified on the command line, tsconfig.json files are ignored. See TypeScript Documentation: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson%5D

e.g.

npx tsc

and the .js files will appear in the ./build directory. Note: the directory build will get created automatically the first time this command is run.

To compile a single ts file in the pwd, creating the js file in the pwd, issue:

npx tsc server.ts

Running the node server

npm run dev

or if you didn’t install Nodemon:

node build/server.js

Testing with cURL (or Postman)

GET

will@zen myserver % curl -X GET http://localhost:8000/notes [{"id":1,"name":"John Doe","age":33},{"id":2,"name":"Jane Doe","age":22},{"id":3,"name":"Will","age":"52"},{"id":4,"name":"Will","age":"52"},{"id":5,"name":"Betsy Doe","age":"7"}]% will@zen myserver %

will@zen myserver % curl -X GET http://localhost:8000/notes/3 {"id":3,"name":"Will","age":"52"}% will@zen myserver %
