How is it different?

Nefelibata (Portuguese for “one who walks on clouds”) is an IndieWeb static website generator written in Python 3 that focus on preserving your content. In order to achieve that goal, it works similarly to common static website generators, with the following design decisions:

  • Each post is a separate directory. The actual post is written in Markdown and stored as an email message, and each post can have its own images, CSS, Javascript and other files.

  • Posts are converted into HTML, and the resulting weblog is composed of only static files. There are no databases, and all extra data is stored in JSON files.

  • External images are locally mirrored when the weblog is built, and the link is altered to point to the local resource. The engine will warn you if the generated HTML has any external resources (CSS, for example).

  • External links are saved to the Wayback Machine, and links are annotated with the archived link and date of archival, allowing readers to follow the original links even if they change in the future.

  • The weblog can be published to different locations, using a plugin architecture. Currently, nefelibata supports publishing to Amazon S3, Neocities, FTP, and IPFS.

The IndieWeb

Nefelibata acknowledges that most interactions occur in social networks like Twitter or Mastodon. The engine can be configured with global or per-post announcers that will post to social networks linking back to the content, so that people can comment and discuss posts outside of the weblog, a concept called POSSE (Publish on your Own Site, Syndicate Elsewhere) in the IndieWeb.

When the weblog is rebuilt, the announcers will collect any replies and store them locally, so that the comments are displayed in the weblog with your post. A post can be announced to multiple social networks, and the comments will be aggregated and preserved.

Getting started

Installation

First install nefelibata using a virtual environment:

$ python -m venv venv
$ source venv/bin/activate
$ pip install nefelibata

This will add a program called nb to your path.

If you’re impatient, you can run:

$ nb init blog
$ cd blog
$ nb build
$ nb preview

And open http://localhost:8000/ to see your weblog. Read below for details.

Creating the weblog directory

Once you have installed nefelibata you should initialize a directory that will hold your content:

$ nb init blog
$ ls blog
nefelibata.yaml  posts/  templates/

Here, the file nefelibata.yaml stores the configuration for your weblog. The posts/ directory will contain your posts, and should already have a directory called first/ with an initial post. The templates/ directory has the templates for generating your blog and its Atom feed. Multiple themes are supported, but there’s currently only one called “pure-blog”, based on Pure.css.

Configuring your weblog

Open the file nefelibata.yaml. The first part is self-explanatory, and you should populate with your information:

title: Example.com
subtitle: A blog about examples
author:
  name: John Doe
  email: john.doe@example.com
  note: This is me
url: https://blog.example.com/  # trailing slash is important
posts-to-show: 5
theme: pure-blog
language: en

# These are social links displayed on the footer
social:
  - title: Code
    url: "https://github.com/example"
    icon: icon-github
  - title: Facebook
    url: "https://www.facebook.com/example"
    icon: icon-facebook
  - title: Twitter
    url: "https://twitter.com/example"
    icon: icon-twitter

Builders

The second part defines which parts of your weblog will be built. Unless you know what you’re doing you shouldn’t change anything here:

builders:
  - post
  - index
  - tags
  - atom

Assistants

The next part defines “assistants”, which are HTML post-processor that run after the builders. Assistants can mirror images locally, save external links in the Wayback Machine, and more:

assistants:
  - mirror_images
  - warn_external_resources
  - playlist
  - archive_links
  - relativize_links

Publishers

The fourth part defines where your weblog will be published to once it’s been built. Neocities is easy to setup and recommended for beginners, but you can also publish to S3, FTP and IPFS:

publish-to:
  - neocities
  - S3
  - ipfs
  - ftp

Each one of the publishers has its own configuration section in the nefelibata.yaml file. For Neocities you only need your username and password:

neocities:
  username: username
  password: password
  # api_key:

After publishing for the first time, nefelibata will print out an API key that you can use instead of your username/password. Simply add it to the configuration file, and comment out the username and password fields.

The S3 section looks like this:

S3:
    AWS_ACCESS_KEY_ID:
    AWS_SECRET_ACCESS_KEY:
    bucket: blog.example.com

    # Nefelibata will configure the bucket as website and also set your DNS
    # if you're using Route 53
    configure_website: true
    configure_route53: blog.example.com.

You need to create an S3 account in order to get the AWS credentials. If you want the S3 publisher to create the bucket, configure it as a website, upload the website and configure Route 53 to point the domain name to it you need the following policy in your IAM account (replace blog.example.com with your domain):

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "s3:GetBucketWebsite",
                "s3:PutBucketWebsite",
                "route53:ChangeResourceRecordSets",
                "s3:PutBucketAcl",
                "s3:CreateBucket"
            ],
            "Resource": [
                "arn:aws:route53:::hostedzone/example.com",
                "arn:aws:s3:::blog.example.com"
            ]
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::blog.example.com/*"
        },
        {
            "Sid": "VisualEditor2",
            "Effect": "Allow",
            "Action": "route53:ListHostedZones",
            "Resource": "*"
        }
    ]
}

This will upload your weblog to an S3 bucket and run the website from it over HTTP. If you want to serve the website over HTTPS (as I do), you need to disable Route 53 (configure_route53 should be empty) and configure CloudFront.

The FTP publisher requires a host, and optionally a username, a password and a directory to which the content should be uploaded to:

ftp:
    host: ftp.example.com
    username: user
    password: secret
    basedir: public

In the example above, the files would be put inside the public directory. You can also specify an absolute path.

For IPFS you need a host running the IPFS daemon. The build/ directory will be sent to the remote host via rsync, added and published to the IPFS. The config itself is simple:

ipfs:
  username: ipfs
  host: ipfs.example.com

The weblog will be published to the InterPlanetary Name System. If you want to give it an accessible and easy to remember name, create a text record for the subdomain _dnslink.blog.example.com with the following content:

_dnslink.blog.example.com descriptive text "dnslink=/ipns/<CID>"

Where CID is the content identifier of your host. You can read more about DNSLink.

Announcers

Finally, the last part is used for syndicating your content. Currently nefelibata can publish to and collect replies from the following websites:

announce-on:
  - webmention
  - mastodon
  - twitter
  - wtsocial
  - medium
  - fawm

Each announcer has its own configuration section, with different requirements. The Mastodon, Twitter and WT.Social announcers will publish the summary of the post, with a link back to the post in the weblog. The Medium announcer will publish the full HTML, on the other hand.

The Webmention announcer is different in that it will check all the links referenced in a post, trying to discover webmention endpoints, and sending a notification is positive. The announcer also collects mentions made to the weblog, by reading them from Webmention.io.

Finally, FAWM is a website where people try to write 14 songs during the month of February. You can only publish to FAWM during February for obvious reasons. If you like making music you should try participating!

Creating a new post

Your skeleton blog already has a post called first/. You can edit that post, or create a new one with the command:

$ nb new "Hello, World!"

(Note that you always need to run the nb command from inside your weblog directory.)

This will create a new directory called hello_world/, with the following structure:

posts/hello_world/
posts/hello_world/index.mkd
posts/hello_world/img/
posts/hello_world/css/
posts/hello_world/js/

If you have the EDITOR environment set, nefelibata will automatically open your editor to edit index.mkd. You can place any custom CSS, Javascript or images in the corresponding directories, or any other extra files in the hello_world/ directory.

You’ll notice that the index.mkd file has headers and a body. The file itself is actually stored as an email, using the RFC 5322 format. The most important headers are:

  • subject: this is the title of your post.

  • summary: this is a one-line summary of your post.

  • keywords: a comma-separated list of keywords/tags/tags.

Additionally, once the post is published a date header will be added. If the post is announced to Twitter/Mastodon/etc. a corresponding header (eg, mastodon-url) will also be added.

If you want to announce your post to a custom social network you can either override the default announcers by using the announce-on header, or add an extra announcer by using the announce-on-extra header. Similarly, if you want to skip a default announcer you can use the announce-on-skip header.

Building the weblog

To build your weblog, simply run:

$ nb build

This will convert the Markdown files to HTML and build the weblog, with pages for archives and tags as well. Later, once posts have been announced to social networks, this command will also collect replies and store them locally.

Previewing the weblog

To preview your weblog, simply run:

$ nb preview

This will run an HTTP server on port 8000. Open http://localhost:8000/ on your browser so you can preview your changes.

Publishing the weblog

Finally, you can publish your weblog with the command:

$ nb publish

This will upload the weblog using any configured publishers (like S3), and announce new posts to social networks.

What’s next?

If you want to customize your weblog, take a look at the templates/ directory inside your weblog. The templates are written in Jinja2.
