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!
Test whether a value is a relative URI.
npm install @stdlib/assert-is-relative-uriAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (see README). - To use as a general utility for the command line, install the corresponding CLI package globally.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
var isRelativeURI = require( '@stdlib/assert-is-relative-uri' );Tests whether a value is a relative URI.
var bool = isRelativeURI( 'foo/bar' );
// returns true
bool = isRelativeURI( 'https://example.com/' );
// returns false- For more information regarding the URI scheme, see RFC 3986 and Wikipedia.
- On the distinction between URI, URL, and URN, see The Difference Between URLs and URIs.

// returns true

npm install -g @stdlib/assert-is-relative-uri-cliUsage: is-relative-uri [options] [<uri>]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
$ is-relative-uri google.com
trueTo use as a standard stream,
$ echo -n 'https://google.com' | is-relative-uri
falseBy default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
$ echo -n 'https://google.com\tbeep' | is-absolute-uri --split '\t'
false

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.
