Generate Google Slides from markdown & HTML. Run from the command line or embed in another application.
This project was developed as an example of how to use the Slides API.
While it does not yet produce stunningly beautiful decks, you are encouraged to use this tool for quickly prototyping presentations.
Contributions are welcome.
For command line use, install md2gslides globally:
npm install -g md2gslidesThen get your OAuth client ID credentials:
- Create (or reuse) a developer project at https://console.developers.google.com
- Enable Google Slides API at API library page
- Go to Credentials page and click "+ Create credentials" at the top
- Select "OAuth client ID" authorization credentials
- Choose type "Computer Application" and give it some name.
- Download client credentials file.
- Copy it to
client_id.json(name has to match) and save to~/.md2googleslides.
After installing, import your slides by running:
md2gslides slides.md --title "Talk Title"This will generate new Google Slides in your account with title Talk Title.
NOTE: The first time the command is run you will be prompted for authorization. OAuth token
credentials are stored locally in a file named ~/.md2googleslides/credentials.json.
Each time you will run the above comment, new slide deck will be generated. In order to work on exactly the same deck, just get the ID of the already generated slides. For example, you can use following command:
# To reuse deck available at: https://docs.google.com/presentation/d/<some id>/edit#
md2gslides slides.md --title "Talk Title" --append <some id> --erase
You can specify a parent folder in which to store the presentation using the --parent or -p option"
# To store the new deck in https://drive.google.com/drive/u/0/folders/<some-id>
md2gslides slides.md --title "Talk Title" --parent <some id>
md2gslides uses a subset of the CommonMark and Github Flavored Markdown rules for markdown.
Each slide is typically represented by a header, followed by zero or more block elements.
Begin a new slide with a horizontal rule (---). The separator
may be omitted for the first slide.
The following examples show how to create slides of various layouts:
---
# This is a title slide
## Your name here
---
# This is a section title
---
# Section title & body slide
## This is a subtitle
This is the body
---
# Title & body slide
This is the slide body.
Add {.big} to the title to make a slide with one big point
---
# This is the main point {.big}
Use {.big} on a header in combination with a body too.
---
# 100% {.big}
This is the body
Separate columns with {.column}. The marker must appear
on its own line with a blank both before and after.
---
# Two column layout
This is the left column
{.column}
This is the right column
md2googleslides does not edit or control any theme related options. Just set a base theme you want on Google Slides directly.
Even if you will use --append option for deck reuse, theme will be not changed.
Images can be placed on slides using image tags. Multiple images can be included. Mulitple images in a single paragraph are arranged in columns, mutiple paragraphs arranged as rows.
Note: Images are currently scaled and centered to fit the slide template.
---
# Slides can have images
Set the background image of a slide by adding {.background} to
the end of an image URL.
---
# Slides can have background images
{.background}
Include YouTube videos with a modified image tag.
---
# Slides can have videos
@[youtube](MG8KADiRbOU)
Include speaker notes for a slide using HTML comments. Text inside the comments may include markdown for formatting, though only text formatting is allowed. Videos, images, and tables are ignored inside speaker notes.
---
# Slide title
{.background}
<!--
These are speaker notes.
-->
Basic formatting rules are allowed, including:
- Bold
- Italics
- Code
- Strikethrough
- Hyperlinks
- Ordered lists
- Unordered lists
The following markdown illustrates a few common styles.
**Bold**, *italics*, and ~~strikethrough~~ may be used. Ordered lists: 1. Item 1 1. Item 2 1. Item 2.1 Unordered lists: * Item 1 * Item 2 * Item 2.1
Additionally, a subset of inline HTML tags are supported for styling.
<span><sup><sub><em><i><strong><b>
Supported CSS styles for use with <span> elements:
colorbackground-colorfont-weight: boldfont-style: italictext-decoration: underlinetext-decoration: line-throughfont-familyfont-variant: small-capsfont-size(must use points for units)
You may also use {style="..."} attributes
after markdown elements to apply styles. This can be used on headers, inline
elements, code blocks, etc.
Use Github style emoji in your text using
the :emoji:.
The following example inserts emoji in the header and body of the slide.
### I :heart: cats :heart_eyes_cat:
Both indented and fenced code blocks are supported, with syntax highlighting.
The following example renders highlighted code.
### Hello World
```javascript
console.log('Hello world');
```
To change the syntax highlight theme specify the --style <theme> option on the
command line. All highlight.js themes
are supported. For example, to use the github theme
md2gslides slides.md --style githubYou can also apply additional style changes to the entire block, such as changing the font size:
### Hello World
```javascript{style="font-size: 36pt"}
console.log('Hello world');
```
Tables are supported via GFM syntax.
Note: Including tables and other block elements on the same slide may produce poor results with overlapping elements. Either avoid or manually adjust the layout after generating the slides.
The following generates a 2x5 table on the slide.
### Top pets in the United States Animal | Number -------|-------- Fish | 142 million Cats | 88 million Dogs | 75 million Birds | 16 million
Images referencing local paths temporarily uploaded and hosted to file.io. File.io is an emphemeral file serving service that generates short-lived random URLs to the upload file and deletes content shortly after use.
Since local images are uploaded to a thrid party, explicit opt-in is required to use this feature.
Include the --use-fileio option to opt-in to uploading images. This applies to file-based images as well
as automatically rasterized content like math expressions and SVGs.
Slides can also include generated images, using $$$ fenced blocks
for the data. Currently supported generated images are math expression (TeX
and MathML) as well as SVG. Rasterized images are treated like local images are require
opt-in to uploading images to a 3rd party service via the --use-fileio option.
Using TeX:
# How about some math? $$$ math \cos (2\theta) = \cos^2 \theta - \sin^2 \theta $$$
SVG
# Or some SVG?
$$$ svg

Like local images, generated images are temporarily served via file.io.
Pull requests for other image generators (e.g. mermaid, chartjs, etc.) are welcome!
You can also pipe markdown into the tool by omitting the file name argument.
With the exception of /bin/md2gslides.js, TypeScript is used throughout and compiled
