Register (tag, link and meta) SEO tags

Seo.use(config)

Register a meta configuration. You must register all metas before to use the library.

• config - Object - Configuration to use.

Example :

    seo.use({
        name: 'name',       // meta configuration ame
        selector: 'name',   // dom selector (.class, #id etc..)
        template: '<template>{value}</template>' // html template
    })

Seo.tag(name)

Generate a tag meta configuration. This configuration produces tags from this html template <{name}>{value}</{name}>.

• name - String | Array - Tag name(s)

Example :

    // Register 'title' tag and produces <title>{value}</title>
    seo.use(seo.tag('title'))
    seo.use(seo.tag([
        'author',
        'section'
    ]))

Seo.metaName(name)

Generate a meta[name=""] meta configuration. This configuration produces tags from this html template <meta name="{name}" content="{value}" />.

• name - String | Array - Tag name(s)

Example :

    // Register 'title' tag and produces <meta name="title" content="{value}" />
    seo.use(seo.metaName('title'))
    seo.use(seo.metaName([
        'keywords',
        'description'
    ]))

Seo.metaProperty(name)

Generate a meta[property=""] meta configuration. This configuration produces tags from this html template <meta property="{name}" content="{value}" />.

• name - String | Array - Tag name(s)

Example :

    // Register 'og:title' tag and produces <meta name="og:title" content="{value}" />
    seo.use(seo.metaProperty('og:title'))
    seo.use(seo.metaProperty([
        'og:site_name',
        'og:description'
    ]))

Seo.link(name)

Generate a link[rel=""] meta configuration. This configuration produces tags from this html template <link rel="{name}" href="{value}" />.

• name - String | Array - Tag name(s)

Example :

    // Register 'favicon' tag and produces <link rel="favicon" href="{value}" />
    seo.use(seo.link('favicon'))
    seo.use(seo.link([
        'icon',
        'robots'
    ]))
