Show HN: Leaflet.pub – a web app for creating and sharing rich documents

170 points by jpereira 4 months ago


Hi HN!

For the last 8 months we've been working on leaflet.pub, a web app for making delightful documents. We're trying to strike a balance between Notion and Google Docs — very fast, ultralight and easy to share, but also supporting rich blocks and multiple pages.

Weirdly, none of the many notetaking/document apps that we could find hit this combination, so we made Leaflet. With it you can:

- Instantly create a doc, without an account - Share read and edit links - Sign-in with email to sync your docs to different devices - Add rich blocks, like canvases, subpages, rsvps, and polls

It's really useful for one-off collaborations, running events, or just when you need a blank page without having to buy into a whole organizational system.

We also spent a lot of time making sure Leaflets look good. We've found that there's a pretty blurry boundary between a document and a website, so making something that people can feel proud to publish online was key.

Here's a couple examples!

- Jake's presentation on Slöjd, traditional handcraft pedagogy (https://leaflet.pub/3d28b4a7-3703-4ae5-aaf6-d270ffe1151f) - Laura's documentation of her website redesign (https://leaflet.pub/14aba696-e894-440a-9d06-917641a2bfce)

Some technical details that might be interesting:

- We do sync and all our client-side state via Replicache, which I really love! - Data is modeled as a set of facts about entities, a la Datomic, forming a graph. This has been flexible enough for us to quickly build new features, like canvases and nested pages, without committing to a single document structure. - We use ProseMirror, but not for the entire document. Instead every text block is a separate ProseMirror instance. This lets us keep the document structure in our database and our schema, without having to dive into ProseMirror's every time we want to modify things.

Our (somewhat messy) source is available here: https://github.com/hyperlink-academy/leaflet if you want to dig deeper!

On the horizon:

- Better home and document organizing features — things like search, tagging, collections etc. - We're really excited about ATProto and Bluesky and are working on a set of lexicons and an AppView for document publishing! This will include a lexicon for rich text documents, as well as one publications, and some concept of memberships or subscriptions. - More blocks! Tables, code blocks, etc.

Some things we're particularly proud of:

- Our list handling - Custom theming - Keyboard handling on iOS Safari (and generally works excellently on mobile) - Side-scrolling multi-page interface - Works as a PWA!

Some things that still need work:

- While faster than others, still a lot of work we can do on performance, both speed when working with very large documents and loading docs generally - Drag and drop and selection in general could be a lot nicer - Keyboard navigation across multiple pages - Multiplayer cursors, and generally real-time sync could be sped up greatly leveraging CRDTs (we already use YJS, just could move updates around faster)

You can create a new document just by visiting https://leaflet.pub (or https://leaflet.pub/new if you're signed in) — would love to hear your thoughts and any feedback if you give it a try!

Just as an FYI: "leaflet" is the name of a popular web mapping JS library. https://leafletjs.com/

May or may not be relevant for you (and is definitely a very different field/product), but if you're releasing client libraries/SDKs of any sort, it might be good to be aware of. There's a large ecosystem of plugin libraries named "leaflet-foo" or "foo-leaflet" etc in addition to the "main" one. If you start releasing any libraries to work with your app (even if they're not JS), you'll likely want to be aware of and work around naming collisions for library names.

Either way, looks nifty!! I love the approach and we need more people willing to do something like this that competes with google docs / etc, but does so by targeting a specific use case / niche / etc and not by trying to do everything.

It'd be great to get code blocks and inline code blocks. Ideally using Markdown syntax. And, if possible to get syntax highlighting, that'd be even better.

But otherwise, this pretty well lines up with an idea that I had just been mulling over in the last 2 days. Which is pretty eery, but well timed. Realistically I wasn't ever going to do it, so I'm glad I may not have to miss out.

Still playing around with it but I have to say, I absolutely adore the side-scrolling feature!

The Make with Leaflet page is good dive into some possibilities https://make.leaflet.pub/

I see its source available, which implies you’re planning on monetizing somehow, do you mind sharing any insight into what that would look like?

I’m always weary of getting involved in a new tool only for the rug pull to happen later.

I do love it when someone does an original take on what a "document" means. I love the intellectual exploration of it. Kudos, genuinely.

I love this a lot. I have spent a great deal of time considering digital document writing. The hybrid of document and canvas is a must and is commonly found in PKMs now (obsidian, logseq, affine). Collaboration features are also a must imo, but not often found due to it being difficult to implement and scale.

Looking forward to tracking this project! Is there a community one could join to get updates?

Some feedback:

– When tapping on the leaflet icon in the bottom left, the whole text area is erased (Safari on iPad).

– The strikethrough icon is a bit hard to recognize, because the stroke merges with the S line. Some text editors use a different letter for that reason, for example a T, and add a small gap along both sides of the stroke to emphasize the overlay (only on the icon, not on the actual text being edited).

– Making the strikethrough line lighter than the text color is a bit unconventional, I’m not sure it helps readability. In the default text size, the line is easy to overlook, also because it is pretty thin (on a hi-DPI display). This is particularly the case on bold and/or italic text.

– No dark mode support, it seems.

Kudos for the multiple ProseMirror instances. I'm building with ProseMirror myself and that's some nice wizardry I haven't thought of.

I can't seem to scroll horizontally very easily, like I have to middle click drag in empty space, is there any reason you are hiding scrollbars?

That's very impressive, super slick. The subpage preview on the parent page works so well I went digging into the source code.

Guys, this is super cool. As someone building a canvas product that also has a (prosemirror) notepad I am super inspired by this. The way you can flick from a canvas on the notepad, back to the notepad, and it doesn't feel like you're locked in to any block because you can still slightly see where you came from.. love it.

All the best!

Nice, I really like it. The embedded elements like POSTS and RSVPs creates a nice shared space feel to it.

Also interesting to see that you chose WhatsApp for the RSVP element. Did you use Twilio for the integration and what was the level of effort needed?

Is it supposed to be a permanent published document? I couldn't find a delete/unpublish option. I guess retaining the first randomly generated URL can be used to delete the content, but still there is no clear way to delete, unpublish.

It seems an advanced version of https://txt.fyi. The balance between simplicity and experience is great. I hope you can continue with the project

The appearance (both the text font and the UI chrome icons and colors) really is not to my liking. I see that you can already change the foreground and background color of your document. Any plans to add more options?

Are the documents encrypted? Is privacy a focus? One major reason that people want to move away from Google Docs and Notion is because of their very invasive privacy policies.

I really love the ui exploration!

I wish canvases had edges connecting nodes

This website is fantastic! I love the layout!

croisillon - 4 months ago

i thought it would be some kind of competitor to canva but not at all, the product is interesting and original, i'll definitely follow it!

my only nitpick at this moment: i like to see my scrollbars on a desktop

simmo9000 - 4 months ago

Well done. Intuitive and simple like this sort of tool should be.

android521 - 4 months ago

it is using Replicache which requires license key. is there a plan to use an alternative that doesn't require license key?

gr4vityWall - 4 months ago

I like how it looks :)

Is there a tutorial for how to self-host it?

pwillia7 - 4 months ago

This is really great -- Thanks for making it.

pazimzadeh - 4 months ago

I like the icons.

Can you edit a button after adding it?

This is what notion should have been.

This is fantastic. Good job. Makes you realise how much clutter is out there (SaaS nonsense, ads, paywalls, bullshit).

Loading the landing page was a breathe of fresh air. Thank you.
