js+bemhtml: Tech to build js with bemhtml templates

[arikon]

We need tech module to build .js files for bundles that include bemhtml templates to render html from bemjson in the browser.

To build such a file we need to build js part using common deps, build bemhtml.js part using techByDeps.js.bemhtml parf of deps and concatenate the result.

exports.deps = [
    // common deps goes here
];

exports.depsByTech = {

    js: {
        bemhtml: [
            // bemhtml deps for js tech goes here
        ]
    }

};

Should take js-bemhtml tech from realty project as a prototype

js-bemhtml tech from realty project

var BEM = require('bem'),
    PATH = require('path'),
    INHERIT = BEM.require('inherit'),
    Q = BEM.require('qq'),
    JS = BEM.require('bem/lib/techs/js').Tech;

exports.Tech = INHERIT(JS, {

    getSuffixes: function() {
        return ['js'];
    },

    getBuildResult: function(prefixes, suffix, outputDir, outputName) {

        var context = this.context,
            opts = context.opts;

        console.log('context.techs', context.createTech('bemhtml') );

        return this.__base(prefixes, suffix, outputDir, outputName).then(function(res) {

            var decl = opts.declaration.then(function(decl) { return { deps: decl.depsByTechs.js.bemhtml } });

            var bemhtmlTech = context.createTech('bemhtml'),
                output = PATH.resolve(opts.outputDir, opts.outputName),
                bemhtmlResults = bemhtmlTech.getBuildResults(
                    bemhtmlTech.getBuildPrefixes(bemhtmlTech.transformBuildDecl(decl), context.getLevels()),
                    PATH.dirname(output) + PATH.dirSep,
                    PATH.basename(output));

            bemhtmlResults.then(function(r) { console.log('bemhtmlResults %j', r) });

            res.unshift('/* BEMHTML */\n');
            return res;
        });

    }
