The aim of the project is to create an easy to use, lightweight, Complete Web Server Framework with default NodeJs HTTP Server.
- The framework also provides default
Secure User Session,Cookie Parser,Flexible Router,Multiple Views,Virtual Directory,Hidden Directory,Template Engine,Nested Master Template Engine,Post Data Handler (with multipart form data and large file),Mimetype Handler,WebStream Handler,JS/CSS Bundler,socket.io Interface,Easy way to bind with IIS/NGINX
Install cwserver by this command npm i cwserver
How to use cwserver core IApplication?
const { App } = require('cwserver');
const app = App();
const port = 8080;
app.on("request-begain", (req) => {
console.log(`${req.method} ${req.path}`);
});
app.on("response-end", (req, res) => {
console.log(`Send ${res.statusCode} ${req.path}`);
});
app.use((req, res, next) => {
res.status(200).send("Hello World...");
});
app.listen(port, () => {
console.log(`Listing port => ${port}`);
});
Or you may use full application by following:
Create createProjectTemplate.js as following
const { createProjectTemplate } = require( 'cwserver' );
createProjectTemplate( {
appRoot: __dirname,
projectRoot: "www" /** Your project root folder name*/,
allExample: false
} );
Then run this commmand node createProjectTemplate
It will create default project template for cwserver in your application root.
Now your appRoot look like this
appRoot
├─┬ wwww ( projectRoot )
│ └─┬ config
│ ├ lib
│ ├ template (this contains master template file)
│ ├ web (this contains temp and cache files)
│ └ index.html
├─ node_modules
├─ server.js
├─ package.json
└─ README.md
After, run this command node server www /**your project root*/
First process app.prerequisites every request and then run app.use
global.cw.server.on( "register-view", ( app, controller, server ) => {
app.prerequisites( ( req, res, next ): void => {
res.setHeader( 'x-frame-options', 'sameorigin' );
return next();
} );
app.use( ( req, res, next ): void => {
res.setHeader( 'x-frame-options', 'sameorigin' );
return next();
} );
} );
global.cw.server.on( "register-view", ( app, controller, server ) => {
controller
.any( '/test-any/*', ( ctx, match ) => {
return ctx.res.json( { reqPath: ctx.path, servedFrom: "/test-any/*", q: match } );
} )
.get( '/task/:id/*', ( ctx, match ) => {
return ctx.res.json( { reqPath: ctx.path, servedFrom: "/task/:id/*", q: match } );
} )
.get( '/dist/*', ( ctx, match ) => {
return ctx.res.json( { reqPath: ctx.path, servedFrom: "/dist/*", q: match } );
} )
.get( '/user/:id/settings', ( ctx, match ) => {
return ctx.res.json( { reqPath: ctx.path, servedFrom: "/user/:id/settings", q: match } );
} );
} );
global.cw.server.on( "register-view", ( app, controller, server ) => {
const vDir = path.join( path.resolve( server.getRoot(), '..' ), "/project_template/test/" );
server.addVirtualDir( "/vtest", vDir, ( ctx ) => {
return mimeHandler.render( ctx, vDir, true );
} );
server.addVirtualDir( "/test-virtual", vDir );
server.addVirtualDir( "/vtest/virtual/", vDir );
} );
Session cookie name use from app.config.json => session.cookie
and session encryption use app.config.json => session.key
global.cw.server.on( "register-view", ( app, controller, server ) => {
controller.get( '/authenticate/:loginId/:roleid', ( ctx, requestParam ) => {
if ( ctx.req.session.isAuthenticated ) {
ctx.res.status( 200 ).type( "html" ).send( `Hello ${ctx.req.session.loginId}` );
} else {
ctx.setSession(/*loginId*/requestParam.query.loginId,/*roleId*/requestParam.query.roleId, /*userData*/{ token: ctx.req.query.token } );
ctx.res.status( 200 ).type( "html" ).send( `Authentication success ${ctx.req.query.loginId}` );
}
return ctx.next( 200 );
} );
} );
global.cw.server.on( "register-view", ( app, controller, server ) => {
controller.get( '/signout', ( ctx, requestParam ) => {
if ( ctx.session.isAuthenticated ) {
ctx.signOut();
}
ctx.redirect( "/" ).next( 302, true );
} );
} );
const { getBodyParser, fsw } = require( 'cwserver' );
global.cw.server.on( "register-view", ( app, controller, server ) => {
const downloadDir = server.mapPath( "/upload/data/" );
if ( !fs.existsSync( downloadDir ) ) {
fsw.mkdirSync( server.mapPath( "/" ), "/upload/data/" );
}
const tempDir = server.mapPath( "/upload/temp/" );
controller.post( '/post-async', async ( ctx ) => {
const parser = getBodyParser( ctx.req, tempDir );
await parser.parseSync();
if ( parser.isUrlEncoded() || parser.isAppJson() ) {
ctx.res.status( 200, { 'Content-Type': 'application/json' } );
ctx.res.end( JSON.stringify( parser.getJson() ) );
parser.dispose();
return ctx.next( 200 );
}
parser.saveAsSync( downloadDir ); parser.dispose();
return ctx.res.status( 200 ).send( "<h1>success</h1>" );
// or
// return ctx.res.asHTML( 200 ).end( "<h1>success</h1>" );
// or
/*const data = [];
parser.getFilesSync( ( file ) => {
data.push( {
content_type: file.getContentType(),

} );
return ctx.res.status( 200 ).json( data );*/
} )
} );
Template can run config.defaultExt file extension or ctx.res.render( ctx, to_file_path )
Example of server-side script in config.defaultExt or app.config.json => template.ext
ctx.res.render( ctx, server.mapPath( `/index${server.config.defaultExt || ".html"}` ) );
Code block:
{%
if( !ctx.session.isAuthenticated ){
return ctx.next( 401, true );

}

You may create server.js file by you:
const { ConsoleColor, initilizeServer } = require( 'cwserver' );
let wwwName = void 0;
if ( process.argv.length > 2 ) {
wwwName = process.argv[2];
} else {
if ( process.env.APP_POOL_ID ) {
wwwName = process.env[process.env.APP_POOL_ID];
}
}
const server = initilizeServer( __dirname, wwwName );
const app = server.init();
process.on( 'exit', () => {
console.log( "Exited..." );
} );
process.on( 'SIGINT', () => {
server.log.error( "Caught interrupt signal" );
server.log.error( "Application Exited..." );
server.log.reset(); server.log.dispose();
setTimeout( () => {
process.exit( 0 );
}, 200 );
} );
app.listen( server.port, () => server.log.write( `
