Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

insert-module-globals

insert implicit module globals (__filename, __dirname, process, global, setImmediate, clearImmediate and Buffer) as a browserify-style transform

build status

example

var mdeps = require('module-deps');
var bpack = require('browser-pack');
var insert = require('insert-module-globals');
function inserter (file) {
    return insert(file, { basedir: __dirname + '/files' });
}

var files = [ __dirname + '/files/main.js' ];
mdeps(files, { transform: inserter })
    .pipe(bpack({ raw: true }))
    .pipe(process.stdout)
;
$ node example/insert.js | node
in main.js: {"__filename":"/main.js","__dirname":"/"}
in foo/index.js: {"__filename":"/foo/index.js","__dirname":"/foo"}

or use the command-line scripts:

$ module-deps main.js | insert-module-globals | browser-pack | node
in main.js: {"__filename":"/main.js","__dirname":"/"}
in foo/index.js: {"__filename":"/foo/index.js","__dirname":"/foo"}

or use insert-module-globals as a transform:

$ module-deps main.js --transform insert-module-globals | browser-pack | node
in main.js: {"__filename":"/main.js","__dirname":"/"}
in foo/index.js: {"__filename":"/foo/index.js","__dirname":"/foo"}

methods

var insertGlobals = require('insert-module-globals')

var inserter = insertGlobals(file, opts)

Return a transform stream inserter for the filename file that will accept a javascript file as input and will output the file with a closure around the contents as necessary to define extra builtins.

When opts.always is true, wrap every file with all the global variables without parsing. This is handy because parsing the scope can take a long time, so you can prioritize fast builds over saving bytes in the final output. When opts.always is truthy but not true, avoid parsing but perform a quick test to determine if wrapping should be skipped.

Use opts.vars to override the default inserted variables, or set opts.vars[name] to undefined to not insert a variable which would otherwise be inserted.

opts.vars properties with a . in their name will be executed instead of the parent object if ONLY that property is used. For example, "Buffer.isBuffer" will mask "Buffer" only when there is a Buffer.isBuffer() call in a file and no other references to Buffer.

If opts.debug is true, an inline source map will be generated to compensate for the extra lines.

events

inserter.on('global', function (name) {})

When a global is detected, the inserter stream emits a 'global' event.

usage

usage: insert-module-globals {basedir}

install

With npm, to get the library do:

npm install insert-module-globals

and to get the bin script do:

npm install -g insert-module-globals

insert custom globals.

insert-module-globals can also insert arbitary globals into files. Pass in an object of functions as the vars option.

var vars = {
    process: function (file, basedir) {
        return {
            id: "path/to/custom_process.js",
            source: customProcessContent
        }
    },
    Buffer: function (file, basedir) {
        return {
            id: 'path/to/custom_buffer.js',
            source: customProcessContent,
            //suffix is optional
            //it's used to extract the value from the module.
            //it becomes: require(...).Buffer in this case.
            suffix: '.Buffer'
        }
    },
    Math: function () {
        //if you return a string,
        //it's simply set as the value.
        return '{}'
        //^ any attempt to use Math[x] will throw!
    }
}

function inserter (file) {
    return insert(file, { vars: vars });
}
mdeps(files, { transform: inserter })
    .pipe(bpack({ raw: true }))
    .pipe(process.stdout)
