About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Create a disposable HTTP server.
npm install @stdlib/net-disposable-http-servervar httpServer = require( '@stdlib/net-disposable-http-server' );Creates a disposable HTTP server; i.e., the server closes immediately after serving provided content.
var opts = {
'html': '<script src="/bundle.js"></script>',
'javascript': 'console.log( "Boop" );'
};
httpServer( opts );The function accepts the following options:
- html:
bufferorstringto serve as HTML content. - javascript:
bufferorstringto serve as JavaScript. - port: server port. Default:
0(i.e., randomly assigned). - maxport: max server port (used when port hunting). Default:
=port. - hostname: server hostname.
- address: server address. Default:
"0.0.0.0". - open:
booleanindicating whether to launch a web browser. Default:false.
To serve HTML content, set the html option. Once the content is requested, the server will close.
var opts = {
'html': '<h1>Beep</h1>'
};
httpServer( opts );To serve JavaScript, set the javascript option. If no HTML is provided, an HTML boilerplate is served and the JavaScript is served as /bundle.js. Once the content is requested, the server will close.
var opts = {
'javascript': 'console.log( "Boop" );'
};
httpServer( opts );If HTML and JavaScript are provided, in order for the JavaScript to be served, the HTML content should request the file /bundle.js.
var opts = {
'html': '<script src="/bundle.js"></script>',
'javascript': 'console.log( "Boop" );'
};
httpServer( opts );To obtain the server handle, provide a callback.
var nextTick = require( '@stdlib/utils-next-tick' );
function onReady( error, server ) {
if ( error ) {
throw error;
}
nextTick( close );
function close() {
server.close();
}
}
var opts = {
'html': html,
'javascript': 'console.log( "Boop" );'
};
httpServer( opts, onReady );- If neither the
htmlorjavascriptoption is set, the server serves an HTML boilerplate and then closes.
var join = require( 'path' ).join;
var readFileSync = require( '@stdlib/fs-read-file' ).sync;
var httpServer = require( '@stdlib/net-disposable-http-server' );
var html = join( __dirname, 'examples', 'fixtures', 'index.html' );
var js = join( __dirname, 'examples', 'fixtures', 'script.js' );
var opts = {
'html': readFileSync( html ),
'javascript': readFileSync( js ),
'port': 7331,
'hostname': 'localhost',
'open': false
};
httpServer( opts, clbk );
function clbk( error, server ) {
if ( error ) {
throw error;
}
// Give the user a few seconds to open her web browser before closing the server...
setTimeout( onTimeout, 5000 );
function onTimeout() {
server.close();
}
}To use as a general utility, install the CLI package globally
npm install -g @stdlib/net-disposable-http-server-cliUsage: temp-http-server [options] (--html path | --js path | --stdin type)
Options:
-h, --help Print this message.
-V, --version Print the package version.
--html path Serve HTML.
--js, --javascript path Serve JavaScript.
--stdin type Type of content: html or javascript.
-p, --port port Server port. Default: 0.
--maxport maxport Max server port. Default: `port`.
--hostname hostname Server hostname.
--address address Server address. Default: 0.0.0.0.
--open Launch a browser once server is ready.
The application recognizes the following environment variables:
DEBUG: enable verbose logging.PORT: server port.MAXPORT: max server port.HOSTNAME: server hostname.ADDRESS: server address.
- Command-line arguments always take precedence over environment variables.
- If either the
--htmlor--javascriptcommand-line flag is set,stdinis assumed to be of the other type. Accordingly, the--stdinflag may be omitted.
To serve an HTML file,
$ DEBUG=* temp-http-server --html ./examples/fixtures/index.html
...To serve a JavaScript file (and a default HTML boilerplate),
$ DEBUG=* temp-http-server --javascript ./examples/fixtures/script.js
...In addition to file input, the application accepts standard input. To pipe HTML,
$ cat ./examples/fixtures/index.html | DEBUG=* temp-http-server --port 7331 --stdin html
...To pipe HTML and load a JavaScript file,
$ cat ./examples/fixtures/index.html | DEBUG=* temp-http-server --port 7331 --javascript ./examples/fixtures/script.js
...To pipe JavaScript (and serve a default HTML boilerplate),
$ cat ./examples/fixtures/script.js | DEBUG=* temp-http-server --address '127.0.0.1' --stdin javascript
...To pipe JavaScript and serve custom HTML content which requests a /bundle.js file,
$ cat ./examples/fixtures/script.js | DEBUG=* temp-http-server --html ./examples/fixtures/index.html
...This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
