Start Server

import { Spear } from "tspace-spear";

new Spear()
.get('/' , () => 'Hello world!')
.get('/json' , () => {
  return {
    message : 'Hello world!'
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

Cluster

import { Spear } from "tspace-spear";
new Spear({
  cluster : 3
})
.get('/' , () => 'Hello world!')
.get('/json' , () => {
  return {
    message : 'Hello world!'
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

Global Prefix

const app = new Spear({
  globalPrefix : '/api' // prefix all routes
})
.get('/' , () => 'Hello world!')
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

// http://localhost:3000/api => 'Hello world!'

Logger

const app = new Spear({
  logger :  true
})
// or use this for logging
.useLogger({
    methods     : ['GET','POST'],
    exceptPath  : /\/benchmark(\/|$)|\/favicon\.ico(\/|$)/ // or use Array ['/']
})
.get('/' , () => 'Hello world!')
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

Format Response

Notfound

const app = new Spear()
.get('/' , () => {
  return { 
    message: 'Hello world'
  }
})
.notfound(({ res } : TContext) => {
  return res.notFound('Not found!')
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))
// http://localhost:3000/notfound => { success: false , message : 'Not found!' , statusCode: 404 }

Response

const app = new Spear()
.get('/' , () => {
  return { 
    message: 'Hello world'
  }
})
.response((results, statusCode) => {

  if(typeof results === 'string') return results
  
  /// ...
  return {
      success : statusCode < 400,
      ...results,
      statusCode
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))
// http://localhost:3000 => { success: true , message : 'Hello World' , statusCode: 200 }

Catch

const app = new Spear()
.get('/' , () => {
  throw new Error('Catching failed')
})
.catch((err : Error , { res } : TContext) => {

  return res
    .status(500)
    .json({
      success    : false,
      message    : err?.message,
      statusCode : 500
  });
}) 
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))
// http://localhost:3000 => { success: false , message : 'Catching failed' , statusCode: 500 }

Cors

const app = new Spear()
.cors({
    origins: [
      /^http:\/\/localhost:\d+$/
    ],
    credentials: true
})
//.cors() allow *
.listen(port , () => console.log(`Server is now allow cors localhost:* `))

Body

new Spear()
// enable body payload
.useBodyParser()
.post('/' , ({ body }) =>  {
  return {
    yourBody : body
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

File Upload

import { Spear } from 'tspace-spear';
import path from 'path'

new Spear()
// use this for enable file upload
.useFileUpload({
  limit : 1000 * 1000, // limit for file upload 1_000_000 bytes by default Infinity
  tempFileDir : 'temp', // folder temporary directory by default tmp
  removeTempFile : {
    remove : true, // remove temporary files by default false
    ms : 1000 * 60 // remove file temporary after 60 seconds
  }
})
.post('/' , ({ files } : TContext) => {

  // you can move the file from temporary to other folder
  // for example please validate the your input file
  const file     = files.file[0]
  const folder   = 'uploads'

  await file.write(path.join(path.resolve(),`${folder}/${+new Date()}.${file.extension}`))

  // after writed the file you should remove the temporary file
  await file.remove()

  return {
    files
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

Cookie

new Spear()
.useCookiesParser()
.post('/' , ({ cookies }) =>  {
  return {
    yourCookies : cookies
  }
})
.listen(3000 , () => console.log(`Server is now listening http://localhost:3000`))

Middleware

// file cat-middleware.ts
export default (ctx : TContext, next: TNextFunction) =>{
  console.log('cat middleware globals');
  return next();
}

import  Spear { Router, TContext, TNextFunction } from "tspace-spear";

(async () => {
  const port = Number(process.env.PORT ?? 3000)
  const app = new Spear({
    middlewares: [ CatMiddleware ]
    // if you want to import middlewares with a directory can you follow the example
    // middlewares : {
    //   folder : `${__dirname}/middlewares`,
    //   name :  /middleware\.(ts|js)$/i

  })

  // or add a middleware
  app.use((ctx : TContext , next : TNextFunction) => {
