NOTICE
Although this plugin still works (and I'm still using it for now), I will no longer be maintining it as I'm working on my own static generator that will do all this and more. I have published the last beta, 2.0.0, as the latest release since there were some bugfixes in the betas that I never got around to publishing and that is the version I use for my blog which seems to be working fine.
metalsmith-organizer
A Metalsmith plugin for organizing posts into groups (pages, posts, archives, etc), including their pagination, permalinks, etc.
It's meant as an all-in-one replacement for plugins such as metalsmith-tags, metalsmith-collections, and metalsmith-pagination. Because of this it should not be used with those plugins or any plugins that group posts like that.
The plugin has been tested with options similar to those shown in the example section. If you have a specific use case in mind that isn't covered and isn't outputting what you expect, open an issue and I'll see what I can do.
Install
npm install metalsmith-organizer
Usage
const metalsmith = require("metalsmith");
const organizer = require("metalsmith-organizer")
metalsmith
//should be used after any post processing (markdown, shorcodes, etc), but before metalsmith-layouts
.use(organizer({
//global options
groups: [
group: {
//group options
}
]
}))
Global Options
permalink_group
The group that will contain the path to the actual posts. Other groups will only create pages and won't be given the proper post data for templates unless that group's override_permalink_group
is set to true
.
drafts
(default false)
True will include posts marked as drafts (by either a draft
, published
or status
property).
make_safe
(function)
If slug is defined, this plugin will use that as the title, otherwise it uses a built in function below to make the title url safe. You can override this by specifying your own function.
//This function is similar to how wordpress makes titles safe.
make_safe: function (string) {
return string.replace(/(-|\/)/g, "").replace(/(\'|\"|\(|\)|\[|\]|\?|\+)/g, "").replace(/(\s)+/g, "-").toLowerCase()
}
groups
(array of objects)
An array containing all the groups with each group being it's own object. If a later group conflicts with an earlier group, it will overwrite it, so order matters.
Group Options
Search Criteria
Any property that is not an option (add_prop
, change_extension
, date_format
, date_page_layout
, expose
, group_name
, no_folder
, num_format
, override_permalink_group
, page_description
, page_layout
, page_only
, path
, per_page
, reverse
, search_type
) can be used as the search criteria to match posts to the group. There can be as many properties as you like but it cannot match multiple of the same property (e.g tags: "tag1, tag2"
or by repeating them tags: "tag1", tags: "tag2
).
Both the search criteria and the properties being searched are made safe with the make_safe
function.
You can also now check whether a property exists with a boolean (e.g thumbnail: true
). This will exclude any posts without that property. Or inversely you can set it to false, and any posts that have that property are excluded.
If you don't specify any search criteria, all posts will be included in the group.
search_type
("any" or "all")
Posts by default must match all
search criteria. Setting this to any
means a post must only match one to be included in that group.
Can also be set globally, with groups overriding it if set.
path
The path to the page or post. The following variables are allowed: {group}, {title}, {num}, {expose}
.
The path should not start or end with forward slashes, it is assumed all paths are relative to root. No extensions should be appended at the end.
In permalink groups {num}
is ignored when creating the actual post, but not for it's pages, allowing you to set the path for say, the archive and posts all in one go (e.g 2017/page/1
and 2017/post
).
If {date}
is used, date_format
should be defined.
If you'd like to use a different layout for date pages, see the date_page_layout
option.
per_page
Maximum number of posts per page on pages. Path must include {num}
.
num_format
If you'd like the url to look something like page/2
when numbering pages, this can be done by setting this option to page/{num}
.
date_format
If you're using {date}
in your path you must specify this option. This plugin uses the moment library to convert dates, so see their documentation for further details on what formats you can use.
The date parts must be seperated by forward slashes though to actually create pages and give the proper files to each page. Setting it to formats such as date_format: "YYYY-MM",
have not been tested.
Using {date}
also adds a dates property to the site metadata which gives you an object that looks like this:
//date_format: "YYYY/MM
//site.dates
{
'2014': {
'01': {
date: '2014/01'
count: 1,
files: [Object]
},
'02': {
date: '2014/02'
count: 1,
files: [Object]
}
},
'2015': {
//and so on
},
}
It can nest itself as deeply as needed.
reverse
(default false)
Reverse sorting order of groups with a date_format.
Default is newest posts first.
date_page_layout
Since the page_layout applies to all pages created in a group and you might want to have archive pages look different, you can set this property to override that. It should be split by the same amount of forward slashes that date_format
is. For example:
date_format: "YYYY/MM",
date_page_layout: "template-year.ext/template-month.ext",
page_layout
(default "index")
The layout to use for pages. Even if this is a permalink group, this only applies to it's pages. For example:
page_layout: "index.ext",
path: "{group}/{title}",
Here the layout would only apply to the group page. The actual post is left alone to be handled by the options set in metalsmith-layouts.
expose
Expose well, "exposes" the given property to use as a dynamic variable. The specified property should not be used to filter posts by (you can still filter by other properties).
That might not make much sense but this is the most powerful part of the plugin. To better explain, suppose you wanted to create a page for each tag, using expose
you can do:
//don't set tags:
expose: "tags"
path: "tags/{expose}"
This causes the tags to be "exposed" as a variable for path
which will then output pages like so tags/tag
, tags/tag-2
, and so on.
Expose also adds the property specified (e.g. "tags"
) as a property of the site metadata, which gives you an object that looks like this:
//site.tags
{
'tag': { nicename: 'tag', count: 4},
'tag 2': { nicename: 'tag-2', count: 4}
}
In pages you can also access an exposed
property, which will tell you what was exposed (e.g. "tags"
) and an exposed_value
(e.g. "tag"
).
override_permalink_group
(default false)
Allows the group to also be a permalink group, otherwise only the "page" data is exposed to the template.
This is useful for pages. E.g. the permalink_group
could be posts
and the pages group can set this to true.
Same path rules apply.
no_folder
(default false)
path: {title}
would normally produce title/index.html
. If this is set to true, it will produce title.html
directly without the folder.
Useful for creating a 404 page, otherwise you would always get 404/index.html
.
add_prop
(array of objects [{property: value}])
Adds the property to any file/post that passed through the group, for use internally with other metalsmith plugins. For example, I want a group to determine which posts will be found by a search plugin so I can do add_prop: [{search: true}]
. Note the property is not exclusive to the group as it is a property of the post itself.
change_extension
(default ".html")
For if you need to generate other filetypes such as xml for feeds and sitemaps.
page_only
(default false)
For when you want just the final page/pages. For example, for generating feeds, you'd want just a list of all the posts available.
Careful not to set override_permalink_group
to true with this. We don't want the individual files actually created.
page_description
(string)
If you want to add a description to the pages created from that group. Format is up to you as this will be handled by your layouts.
Example
.use(organizer({
permalink_group: "posts",
drafts: false,
groups: [
{ group_name: "posts",
type: "post", //get all posts, exclude pages
path: "{date}/{num}/{title}", //creates paginated archives and permalinks
date_format: "YYYY/MM", //posts look like: /2017/01/post/index.html
date_page_layout: "index-year.ext/index-month.ext", //use one template for the year and another for the months,
num_format: "page/{num}", //archives look like /2017/01/page/2/index.html
per_page: 10,
add_prop: [{search: true}] //for use with a plugin later
},
{ group_name: "index",//for the home page
type: "post",//get all posts, exclude pages
page_layout: "index.ext",//use index template
path: "{num}",
num_format: "page/{num}", //home pages will look like: /page/2/index.html, /page/3/index.html, and so on.
per_page:10,
},
{ group_name: "tag"
type: "post",//get all posts, exclude pages
expose: "tags", //expose the tags property
path: "tags/{expose}/{num}", //this will create tag pages that look like so: tags/tag/index.html, tags/tag2index.html, and so on
num_format: "page/{num}", //this will paginate each tag page like so: tags/tag/page/2/index.html, tags/tag2/page/2/index.html, and so on.
per_page:10,
},
{ group_name: "pages",
type: "page", //get pages, exclude posts
path: "{title}", //this will create "post" pages that look like: about/index.html, contact/index.html, etc.
override_permalink_group: true, //so that we actually get the page data in our template
},
{ group_name: "error",
title: "404", //get 404 "post"
path: "{title}",
override_permalink_group: true, //again we need to pass the right data to the template
no_folder: true //path would normally create a file at 404/index.html but the no folder forces it to output 404.html
},
{ group_name: "portfolio",
type: "post", //get all posts...
tags: "thumb",//...that also have a thumb
thumb_url: true, //check that a thumb url property exists
path: "{group}", //make the path the group name so we get portfolio/index.html
//no per_page means it we don't need to specify anything about page numbers, it's just a single page
page_layout: "index-masonry-thumb.ext", //use a different template
},
{ group_name: "rss",
type: "post", //get all posts like the post group
path: "{group}", //url will be at rss/index.xml
change_extension: ".xml", //change our extension
page_layout: "rss", //use our rss template
page_only: true // only the "pages" so that we get a list of all our post files
},
{ group_name: "tag_rss",//then say we wanted an rss feed for every tag
type: "post", //we use the same search criteria as the tags group
expose: "tags", //also the same expose so that it's broken into the correct groups of pages
path: "tag/{expose}/rss",
//the path is a little different because we can't just use {group} and also I want it to be in an rss subfolder to link to so we manually specify it so we'll get files output at tags/tag/rss/index.xml, tags/tag2/rss/index.xml
page_only: true, // we don't want all the individual files created
change_extension: ".xml" //change our extension
page_layout: "rss.ext", //change our template to the rss template
},
{ group_name: "sitemap", //similarly to how we made an rss feed we can make a sitemap
//the cool thing about making it this way is you have access to the post so you can do stuff in your templates (if the logic of the language allows it, I use ejs which is just javascript really and lets me do anything I want) like check if the content has videos, etc, then output that information to the sitemap for better SEO
page_layout: "sitemap.ext", //change to my sitemap template
path: "{group}",
no_folder: true, //so we get sitemap.xml at the root
change_extension: ".xml", //change out extension
page_only: true, //because again we don't actually need to create any individual files
},

Note
I tested this with metalsmith-layouts using ejs as my template engine. Now I'm not sure if it's ejs, metalsmith-layouts, or maybe I'm just doing something wrong, but I could not get my index template to output correctly, that is, when I tried to call the contents variable inside an index template, the post contents were already processed by the single template. So as a quick fix I forced this plugin to copy the contents into an original_contents property.
