Typst Packages

The package repository for Typst, where package authors submit their packages. The packages submitted here are available on Typst Universe.

Package format

A package is a collection of Typst files and assets that can be imported as a unit. A typst.toml manifest with metadata is required at the root of a package. An example manifest could look like this:

[package]
name = "example"
version = "0.1.0"
entrypoint = "lib.typ"
authors = ["The Typst Project Developers"]
license = "MIT"
description = "An example package."

Required by the compiler:

• name: The package's identifier in its namespace.
• version: The package's version as a full major-minor-patch triple. Package versioning should follow SemVer.
• entrypoint: The path to the main Typst file that is evaluated when the package is imported.

Required for submissions to this repository:

• authors: A list of the package's authors. Each author can provide an email address, homepage, or GitHub handle in angle brackets. The latter must start with an @ character, and URLs must start with http:// or https://.
• license: The package's license. Must contain a valid SPDX-2 expression describing one or multiple OSI-approved licenses.
• description: A short description of the package. Double-check this for grammar and spelling mistakes as it will appear in the package list.

Optional:

• homepage: A link to the package's web presence, where there could be more details, an issue tracker, or something else. Will be linked to from the package list.
• repository: A link to the repository where this package is developed. Will be linked to from the package list if there is no homepage.
• keywords: An array of search keywords for the package.
• categories: An array with up to three categories from the list of categories to help users discover the package.
• disciplines: An array of disciplines defining the target audience for which the package is useful. Should be empty if the package is generally applicable.
• compiler: The minimum Typst compiler version required for this package to work.
• exclude: An array of globs specifying files that should not be part of the published bundle that the compiler downloads when importing the package. To be used for large support files like images or PDF documentation that would otherwise unnecessarily increase the bundle size. Don't exclude the README or the LICENSE.

Packages always live in folders named as {name}/{version}. The name and version in the folder name and manifest must match. Paths in a package are local to that package. Absolute paths start in the package root, while relative paths are relative to the file they are used in.

Templates

Packages can act as templates for user projects. In addition to the module that a regular package provides, a template package also contains a set of template files that Typst copies into the directory of a new project.

In most cases, the template files should not include the styling code for the template. Instead, the template's entrypoint file should import a function from the package. Then, this function is used with a show rule to apply it to the rest of the document.

Template packages (also informally called templates) must declare the [template] key in their typst.toml file. A template package's typst.toml could look like this:

[package]
name = "charged-ieee"
version = "0.1.0"
entrypoint = "lib.typ"
authors = ["Typst GmbH <https://typst.app>"]
license = "MIT-0"
description = "An IEEE-style paper template to publish at conferences and journals for Electrical Engineering, Computer Science, and Computer Engineering"

[template]
path = "template"
entrypoint = "main.typ"
thumbnail = "thumbnail.png"

Required by the compiler:

• path: The directory within the package that contains the files that should be copied into the user's new project directory.
• entrypoint: A path relative to the template's path that points to the file serving as the compilation target. This file will become the previewed file in the Typst web application.

Required for submissions to this repository:

• thumbnail: A path relative to the package's root that points to a PNG or lossless WebP thumbnail for the template. The thumbnail must depict one of the pages of the template as initialized. The longer edge of the image must be at least 1080px in length. Its file size must not exceed 3MB. Exporting a PNG at 250 DPI resolution is usually a good way to generate a thumbnail. You are encouraged to use oxipng to reduce the thumbnail's file size. The thumbnail will automatically be excluded from the package files and must not be referenced anywhere in the package.

Template packages must specify at least one category in package.categories.

If you're submitting a template, please test that it works locally on your system. The recommended workflow for this is as follows:

• Add a symlink from $XDG_DATA_HOME/typst/packages/preview to the preview folder of your fork of this repository (see the section on local packages).
• Run typst init @preview/mypkg:version. Note that you must manually specify the version as the package is not yet in the index, so the latest version won't be detected automatically.
• Compile the freshly instantiated template.

Third-party metadata

Third-party tools can add their own entry under the [tool] section to attach their Typst-specific configuration to the manifest.

[package]
# ...

[tool.mytool]
foo = "bar"

Published packages

This repository contains a collection of published packages. Due to its early and experimental nature, all packages in this repository are scoped in a preview namespace. A package that is stored in packages/preview/{name}/{version} in this repository will become available in Typst as #import "@preview/{name}:{version}". You must always specify the full package version.

You can use template packages to create new Typst projects with the CLI with the typst init command or the web application by clicking the Start from template button.

Submission guidelines

To submit a package, simply make a pull request with the package to this repository. There are a few requirements for getting a package published, which are detailed below:

• Naming: Package names should not be the obvious or canonical name for a package with that functionality (e.g. slides is forbidden, but sliding or slitastic would be ok). We have this rule because users will find packages with these canonical names first, creating an unfair advantage for the package author who claimed that name. Names should not include the word "typst" (as it is redundant). If they contain multiple words, names should use kebab-case. Look at existing packages and PRs to get a feel for what's allowed and what's not.

  Additional guidance for template packages: It is often desirable for template names to feature the name of the organization or publication the template is intended for. However, it is still important to us to accommodate multiple templates for the same purpose. Hence, template names shall consist of a unique, non-descriptive part followed by a descriptive part. For example, a template package for the fictitious American Journal of Proceedings (AJP) could be called organized-ajp or eternal-ajp. Package names should be short and use the official entity abbreviation. Template authors are encouraged to add the full name of the affiliated entity as a keyword.

  The unamended entity name (e.g. ajp) is reserved for official template packages by their respective entities. Please make it clear in your PR if you are submitting an official package. We will then outline steps to authenticate you as a member of the affiliated organization.

  If you are an author of an original template not affiliated with any organization, only the standard package naming guidelines apply to you.

• Functionality: Packages should conceivably be useful to other users and should expose their capabilities in a reasonable fashion.

• Documentation: Packages must contain a README.md file documenting (at least briefly) what the package does and all definitions intended for usage by downstream users. Examples in the README should show how to use the package through an @preview import. If you have images in your README, you might want to check whether they also work in dark mode. Also consider running typos through your package before release.

• Style: No specific code style is mandated, but two spaces of indent and kebab-case for variable and function names are recommended.

• License: Packages must be licensed under the terms of an OSI-approved license. In addition to specifying the license in the TOML manifest, a package must either contain a LICENSE file or link to one in its README.md.

  Additional details for template packages: If you expect the package license's provisions to apply to the contents of the template directory (used to scaffold a project) after being modified through normal use, especially if it still meets the threshold of originality, you must ensure that users of your template can use and distribute the modified contents without restriction. In such cases, we recommend licensing at least the template directory under a license that requires neither attribution nor distribution of the license text. Such licenses include MIT-0 and Zero-Clause BSD. You can use an SPDX AND expression to selectively apply different licenses to parts of your package. In this case, the README or package files must make clear under which license they fall. If you explain the license distinction in the README file, you must not exclude it from the package.

• Size: Packages should not contain large files or a large number of files. This will be judged on a case-by-case basis, but if it needs more than ten files, it should be well-motivated. To keep the package small and fast to download, please exclude images for the README or PDF files with documentation from the bundle. Alternatively, you can link to images hosted on a githubusercontent.com URL (just drag the image into an issue).

• Security: Packages must not attempt to exploit the compiler or packaging implementation, in particular not to exfiltrate user data.

• Safety: Names and package contents must be safe for work.

This list may be extended over time as improvements/issues to the process are discovered. Given a good reason, we reserve the right to reject any package submission.

When a package's PR has been merged and CI has completed, the package will be available for use. However, it can currently take a longer while until the package will be visible on Typst Universe. We'll reduce this delay in the future.

Once submitted, a package will not be changed or removed without good reason to prevent breakage for downstream consumers. By submitting a package, you agree that it is here to stay. If you discover a bug or issue, you can of course submit a new version of your package.

There is one exception: Minor fixes to the documentation or TOML metadata of a package are allowed if they can not affect the package in a way that might break downstream users.

Downloads

The Typst compiler downloads packages from the preview namespace on-demand. Once used, they are cached in {cache-dir}/typst/packages/preview where {cache-dir} is

• $XDG_CACHE_HOME or ~/.cache on Linux
• ~/Library/Caches on macOS
• %LOCALAPPDATA% on Windows

Importing a cached package does not result in network access.

Local packages

Want to install a package locally on your system without publishing it or experiment with it before publishing? You can store packages in {data-dir}/typst/packages/{namespace}/{name}/{version} to make them available locally on your system. Here, {data-dir} is

• $XDG_DATA_HOME or ~/.local/share on Linux
• ~/Library/Application Support on macOS
• %APPDATA% on Windows

Packages in the data directory have precedence over ones in the cache directory. While you can create arbitrary namespaces with folders, a good namespace for system-local packages is local:

• Store a package in ~/.local/share/typst/packages/local/mypkg/1.0.0
• Import from it with #import "@local/mypkg:1.0.0": *

Note that future iterations of Typst's package management may change/break this local setup.
