Node-ajax-seo NPM

node-ajax-seo

Simple node plugin that deals with the most popular crawlers (Google, Facebook, Twitter, Baidu, LinkedIn), redirecting them to static snapshots while serves fresh pages to human users. It doesn't generate your snapshots, only routes. For that sort of things we have other nice modules ;-)

npmjs page

Installation

npm install node-ajax-seo --save

Usage

Options:

-nonAjaxCondition    (regex|string) regex condition (better choice this) or typical "if condition" as string to delimite non-ajax pages.

For example: 
/((^\/admin)|(^\/api)|(\.)|(^\/$))/ 
Same result as:
    "(req.url.indexOf('/admin') == -1 && req.url.indexOf('/api') == -1 && req.url.indexOf('.') == -1 && req.url != '/')"

-ajaxPath    (string) path to your main SPA .html by default.

-staticPages.path    (string) path to your static files.

-staticPages.separator    (string) in your static snapshots, filenames contain some token replacing "/" path ("[---]" by default).

-staticPages.basePath.url    (string) basepath is an special case: "when path is X, serve file Y" ("/" by default).

-staticPages.basePath.file    (string) ("index.html" by default). 

-debug		(boolean) Enables debug messages (false by default).

Examples

	var ajaxSeo = require("node-ajax-seo");

Minimal config:

	var siteConfig = {
        nonAjaxCondition: /((^\/admin)|(^\/api)|(\.)|(^\/$))/,
        ajaxPath: path.join(__dirname, 'assets', 'index.html'),
        staticPages: {
            path: path.join(__dirname, 'assets', 'dist', 'static'),
        }
    };

    ajaxSeo.dealWithAjax(siteConfig, req, res, next, function cbk(err) {
        if (err) {
            console.log(err);
        }
        else {
            console.log(siteConfig.appPrefix+'Sent:', path.join(filePath,fragment));
        }
    });

Normal config:

	
  	app.get("/*", function(req, res,next) {

	    /**
	     * It's necessary to define a pattern that matches with non ajax requests:
	     * In this example all the paths are ajax except:
	     *
	     * - /admin and /api paths.
	     * - resource requests.
	     * - root
	     **/

	    var siteConfig = {
	        nonAjaxCondition: /((^\/admin)|(^\/api)|(\.)|(^\/$))/,
	        ajaxPath: path.join(__dirname, 'assets', 'index.html'),
	        staticPages: {
	            path: path.join(__dirname, 'assets', 'dist', 'static'),
	            separator: "[---]",
	            basePath: {
	                url: "/",
	                file: "home.html"
	            }
	        },
	        debug: false
	    };

	    ajaxSeo.dealWithAjax(siteConfig, req, res, next, function cbk(err) {
	        if (err) {
	            console.log(err);

	            // if we don't have snapshot, we can serve 404 page, log miss request into DB, send a mail... whatevevr,
	            // but the best option in this case is to generate it and serve it on-the-fly (WIP).
	            console.log(siteConfig.appPrefix+"We serve the  default file caused by the inexistence of the requested one.");
	            //res.status(err.status).end();
	            res.sendfile(path.join(siteConfig.staticPages.path,siteConfig.staticPages.basePath.file));
	        }
	        else {
	            console.log(siteConfig.appPrefix+'Sent:', path.join(filePath,fragment));
	        }
	    });
	});
