    assert

    The assert module from Node.js, for the browser.

    Build Status npm npm

    With browserify, simply require('assert') or use the assert global and you will get this module.

    The goal is to provide an API that is as functionally identical to the Node.js assert API as possible. Read the official docs for API documentation.

    Install

    To use this module directly (without browserify), install it as a dependency:

    npm install assert
    

    Usage

    The goal is to provide an API that is as functionally identical to the Node.js assert API as possible. Read the official docs for API documentation.

    Inconsistencies with Node.js assert

    Due to differences between browsers, some error properties such as message and stack will be inconsistent. However the assertion behaviour is as close as possible to Node.js and the same error code will always be used.

    Contributing

    To contribute, work on the source files. Then build and run the tests against the built files. Be careful to not introduce syntax that will be transpiled down to unsupported syntax. For example, for...of loops will be transpiled to use Symbol.iterator which is unavailable in IE.

    Build scripts

    npm run build

    Builds the project into the build dir.

    npm run dev

    Watches source files for changes and rebuilds them into the build dir.

    npm run test

    Builds the source files into the build dir and then runs the tests against the built project.

    npm run test:nobuild

    Runs the tests against the built project without rebuilding first.

    This is useful if you're debugging in the transpiled code and want to re-run the tests without overwriting any changes you may have made.

    npm run test:source

    Runs the tests against the unbuilt source files.

    This will only work on modern Node.js versions.

    npm run test:browsers

    Run browser tests against the all targets in the cloud.

    Requires airtap credentials to be configured on your machine.

    npm run test:browsers:local

    Run a local browser test server. No airtap configuration required.

    When paired with npm run dev any changes you make to the source files will be automatically transpiled and served on the next request to the test server.
