bonce v0.2.0

BONCE

Browserify npm modules once for a Meteor package. Avoids a published package rebrowserifying a file which is always the same because the npm modules are set at a fixed version. It generates the file for the package and makes that one file part of the published package so it is never rebuilt.

When I made the Meteor build plugin cosmos:browserify I expected it to make the browserified file during package publishing and then just use it for an app. Instead, published packages retain their originals and build along with the app they're added to (there are benefits to this, just not for this use case).

This cli tool makes it easy to generate a browserified file for a package to use without rebuilds. When you want to update it, you use npm to update the modules and then rerun bonce to generate a new file. Then, publish a new version of your package which has the new file.

Although Meteor's 1.2 Build API provides a caching feature which avoids many browserify operations this cli makes it possible to avoid 100% of rebrowserifying. When a package is added to an app via meteor add user:package it will contain the already browserified file and will never be rebuilt.

Note: It's possible to learn to use the Browserify CLI directly and do all this, and more, with it. I'm making bonce function specifically for making a file for a Meteor package with reasonable (helpful) defaults. For common simple use it only requires you type bonce and then add the resulting file to your package.js file.

[Some Future Plans]

Install

npm install -g bonce

Usage: Basic

Minimal steps using defaults for common case:

1. install bonce globally
2. move into your meteor package's directory
3. install some npm modules into node_modules
4. use bonce to browserify the installed modules into a single file

To update the npm modules and generate a new browserified file repeat the same steps, except #1, of course.

npm install -g bonce
cd yourPackage
npm install some-module another-module
bonce
; same as:
bonce . package.browserified.js node_modules/options.json some-module#someModule another-module#anotherModule

Examples

Check out the example packages to see Meteor packages using bonce.

Command:

bonce [-q | --quiet] [dir with node_modules] [*browserify.js] [*.js] [*.json] [not] [moduleName[/subpath][#varName]]*

All options are optional and the order you specify them is irrelevant.

Command Options: Ordering

The order doesn't matter because it can figure them out by looking at them. Only one option is a directory, two are JS files, but, the input file should have browserify.js in its tail, one is a JSON file, and the others are module names (or the not inverter).

Command Options: Root Directory (basedir)

This is the directory with the node_modules.

By default, bonce uses the present working directory, '.', as the basedir.

Command Options: Input File

You can avoid providing an input file. Read on, and, read Specifying Modules.

By default, bonce will look for an input file at node_modules/browserify.js. So, when the input file has that name it doesn't need to be specified on the command line or in the options file.

The cosmos:browserify build tool expects an input file where variables and require statements are specified. This is passed to Browserify as the entry file. Although this is possible with bonce it can be avoided.

1. by default each installed module will be required and assigned to a variable created from the module's name. It will remove invalid characters from the module name and convert to camel case. For example, module upper-case becomes upperCase.
2. you may specify the name of the variable by naming the module to require in the command, or the options file. Put a # symbol after the name of the module and then the name of the variable. For example, to require the upper-case module and assign it to a variable named toUpperCase use: upper-case#toUpperCase.

If you still want to specify an input file simply put the path to the file in the command, or options file, and ensure the name ends with 'browserify.js' (that can be the whole name). If you want the file to be in your Meteor package directory (makes sense) then it must be hidden from the Meteor build tool by placing the file inside the top of node_modules directory.

Command Options: Output File

This is the browserified result to add to your package.js file.

By default, the browserified result is written to a file at <basedir>/package.browserified.js.

Or, specify its name and where to put it in the command or the options file with a name ending with '.js' and not 'browserify.js' (that's the input file option's tail).

Command Options: Options File

To provide advanced options, and make the command easily repeatable as just bonce, you may specify an options file.

By default, bonce will look for an options file at node_modules/options.json.

Placing the options file in your package will cause Meteor's build tool to complain about its existence. A simple workaround for that is to place the options file in the root of the node_modules directory. Meteor ignores that directory and the file being there won't affect npm using the node_modules directory.

The options file is a JSON file. The bonce command assumes a path to a JSON file is the options file.

Look at the with-options example package using an options file.

Command Options: Specifying Modules

By default, bonce will browserify all modules in the node_modules directory. It exports them to variables created from the module name as described below.

You can specify names to limit which modules are browserified. The name has 3 possible parts:

<module name>/<subpath>#variableName

1. first, is the npm module name. it must match the name of the module installed into node_modules
2. second, you may optionally specify a subpath into the module, for example: some-module/subpath.
3. third, you may optionally specify the name of the variable to export the module to. by default it will convert the module name to a valid variable name, for example, 'upper-case' becomes 'upperCase'.

Instead of specifying the modules to include, you may specify the modules to exclude by putting not before the names of modules. For example:

bonce not some-module

Command Options: Quiet

bonce outputs the options it's using and a success message unless you specify quiet via the short or long option (-q, --quiet).

Command Options: Show Generated Input

When bonce generates an input file for Browserify you may want to see it. Specify the option (-g, --showgen) and bonce will print it out to the console for you.

Command Options: Dry Run

Specify --dryrun and bonce will not perform the browserify operation. It will output the options it has, unless the quiet option is specified. This helps to test what options bonce will use.

You may also set --showgen (or -g) to see the generated input file.

Why name it bonce ?

I wanted something related to the phrase browserify once and bonce wasn't used in the npm registry.
