Wrap `require` in a try/catch block.
npm install @stdlib/utils-try-requireWe 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!

> Wrap require in a try/catch block.
``bash`
npm install @stdlib/utils-try-require
`javascript`
var tryRequire = require( '@stdlib/utils-try-require' );
#### tryRequire( id )
Wraps require in a try/catch block. If able to resolve a module id, the function returns the value bound to module.exports in the resolved module. Otherwise, the function returns an Error.
`javascript
var x = tryRequire( 'beep' );
if ( x instanceof Error ) {
console.log( x.message );
}
`
- Use caution when attempting to resolve a relative path or a local module. This function attempts to resolve a module from its current path. Thus, the function is unable to resolve anything which is not along its search path. For local requires, use an absolute file path.
`javascript
var resolve = require( 'path' ).resolve;
var out = tryRequire( resolve( '/foo/bar/baz', '..', 'lib', 'beep.js' ) );
if ( out instanceof Error ) {
console.error( out.message );
}
`
`javascript
var tryRequire = require( '@stdlib/utils-try-require' );
var out = tryRequire( '_abcdefghijklmnopqrstuvwxyz123456789_' );
if ( out instanceof Error ) {
console.error( out.message );
} else {
throw new Error( 'expected an error' );
}
out = tryRequire( '@stdlib/utils-try-require' );
if ( out !== tryRequire ) {
throw new Error( 'expected export' );
}
