A CLI app to automate conversion and export of tldraw URLs and .tldr
files into SVG or PNG image formats, exposing a number of options along the way. It also provides commands for opening tldraw files in either local or remote instances of the tldraw editor website.
This could be useful in the context of a content publishing pipeline where you want to use a .tldr
file (perhaps under version control) as the "source of truth" for assets to be embedded elsewhere, and you don't want to manage the export of that diagram manually.
For .tldr
file import support in Vite projects, please see @kitschpatrol/vite-plugin-tldraw.
Invoke directly:
npx @kitschpatrol/tldraw-cli export some-file.tldr
...or install locally:
npm install --save-dev @kitschpatrol/tldraw-cli
...or install globally:
npm install --global @kitschpatrol/tldraw-cli
Note
As of version 4.5.0, command line functionality is aliased to both tldraw
and tldraw-cli
.
The less verbose tldraw
command is preferred. The tldraw-cli
alias is deprecated and will be removed in the next major version.
CLI tools for tldraw.
This section lists top-level commands for tldraw
.
Usage:
tldraw <command>
Command | Argument | Description |
---|---|---|
export |
<files-or-urls..> |
Export a local tldraw ".tldr" file or a tldraw.com URL to an svg, png, json, or tldr file. Prints the absolute path(s) to the exported image(s) to stdout. |
open |
[files-or-urls..] |
Open a tldraw .tldr file or tldraw.com URL in your default browser with either the official tldraw.com site or a locally-hosted instance of the editor. Call open without an argument to open a blank sketch. Sketches opened via URL with the --local flag will be temporarily copied to the local system, and will not be kept in sync with tldraw.com. This process does not exit until the browser is closed. Warning: Passing a local .tldr file without the --local option will upload and share the sketch on tldraw.com. |
Option | Description | Type |
---|---|---|
--help -h |
Show help | boolean |
--version -v |
Show version number | boolean |
See the sections below for more information on each subcommand.
Export a local tldraw ".tldr" file or a tldraw.com URL to an svg, png, json, or tldr file. Prints the absolute path(s) to the exported image(s) to stdout.
Usage:
tldraw export <files-or-urls..>
Positional Argument | Description | Type |
---|---|---|
files-or-urls |
The tldraw sketch to export. May be one or more paths to local .tldr files, or tldraw.com sketch URLs. Accepts a mix of both file paths and URLs, and supports glob matching via your shell. Prints the absolute path(s) to the exported image(s) to stdout . (Required.) |

To export the file your-drawing.tldr
to an SVG named your-drawing.svg
in the current working directory, run the following command. Note that the default output format is SVG, and the default export location is the current working directory.
tldraw export your-drawing.tldr
The file will retain its original name, e.g. your-drawing.svg
tldraw export https://www.tldraw.com/s/v2_c_JsxJk8dag6QsrqExukis4
The tldraw.com URL's id (e.g. v2_c_JsxJk8dag6QsrqExukis4
) will be used for the file name.
This is approximately equivalent to clicking the tldraw.com "☰ → Edit → Export As → SVG" menu item.
tldraw export https://www.tldraw.com/s/v2_c_JsxJk8dag6QsrqExukis4 --format tldr
This is approximately equivalent to clicking the tldraw.com "☰ → File → Save a copy" menu item.
Note that using --format tldr
with a file path instead of a URL will still send the file through the pipeline, but it's effectively a no-op. (Except perhaps in rare edge cases where tldraw performs a file format version migration).
tldraw export your-drawing.tldr --format png
This is approximately equivalent to clicking the tldraw.com "☰ → Edit → Export As → PNG" menu item.
tldraw export your-drawing.tldr --transparent --format png
This is approximately equivalent to checking the tldraw.com "☰ → Edit → Export As → ☐ Transparent" menu item.
tldraw export your-drawing.tldr --output ~/Desktop
Exports to ~/Desktop/your-drawing.svg
tldraw export your-drawing.tldr --output ~/Desktop --name not-your-drawing
Exports to ~/Desktop/not-your-drawing.svg
tldraw export https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw --frames
The exported files will be suffixed with their frame name, e.g.:
v2_c_FI5RYWbdpAtjsy4OIKrKw-frame-1.png
v2_c_FI5RYWbdpAtjsy4OIKrKw-frame-2.png
v2_c_FI5RYWbdpAtjsy4OIKrKw-frame-3.png
The frame name will be slugified.
It's possible in tldraw to give multiple frames in a single sketch the same name. In these cases, the frame ID is used in addition to the name to ensure unique output file names.
tldraw export https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw --frames "Frame 3"
tldraw export https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw --frames "Frame 1" "Frame 3"
tldraw export https://www.tldraw.com/s/v2_c_L_RFQ3mJA_BWHejdH2hlD --pages "Page 3"
tldraw export https://www.tldraw.com/s/v2_c_L_RFQ3mJA_BWHejdH2hlD --pages 0 2
tldraw export https://www.tldraw.com/s/v2_c_L_RFQ3mJA_BWHejdH2hlD --pages
tldraw export https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw --format "json"
The .tldr
file format is also JSON under the covers, but the --format json
flag will yield a slightly different format than --format tldr
. --format json
is equivalent to what's produced via the tldraw.com "☰ → Edit → Export As → JSON" menu item.
I'm not completely clear on the use-case for this format, but since tldr.com supports it, so too shall tldraw-cli
.
tldraw export https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw --print
tldraw open https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw
The remote sketch is copied to a locally-hosted instance of tldraw, which is then opened in your default browser.
The tldraw-cli
command line functionality is also provided in module form for programmatic use in TypeScript or JavaScript Node projects.
The library exports two async function, tldrawToImage
, and tldrawOpen
.
This mirrors the tldraw export
CLI command.
It takes an options argument mirroring the arguments available via the command line. The same default values apply:
async function tldrawToImage(
tldrPathOrUrl: string,
{
dark?: boolean
format?: 'svg' | 'png' | 'json' | 'tldr'
frames?: boolean | string[]
name?: string
output?: string
padding?: number
pages?: boolean | string[] | number[]
print?: boolean
scale?: number
stripStyle?: boolean
transparent?: boolean
}): Promise<string[]>;
The function exports the image in the requested format and returns an array of the output image(s) or file(s).
Generally, a single file is returned — but the string[]
return type also accommodates invocations with frame: true
where multiple images will be generated.
Assuming you've installed @kitschpatrol/tldraw-cli
locally in your project, it may be used as follows:
// tldraw-cli-api-test.ts
import { tldrawToImage } from '@kitschpatrol/tldraw-cli'
// Convert a local file to PNG
const [imagePath] = await tldrawToImage('./some-file.tldr', { format: 'png', output: './' })
console.log(`Wrote image to: "${imagePath}"`)
// Convert a remote tldraw.com URL to SVG
await tldrawToImage('https://www.tldraw.com/s/v2_c_JsxJk8dag6QsrqExukis4')
// Convert all frames from a single tldraw.com URL to separate SVGs
// When the `frames` option is set, the function returns an array
// of resulting file paths, instead of a solitary string
const framePathsArray = await tldrawToImage('https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw', {
frames: true,
})
console.log(`Wrote frames to: "${framePathsArray}"`)
// Convert a specific frame from a tldraw.com URL to a PNG
await tldrawToImage('https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw', {
frames: ['Frame 3'],
format: 'png',
})
// You can also use the frame id instead of the frame name, if you're into that sort of thing
// It will work with or without the `shape:` prefix
await tldrawToImage('https://www.tldraw.com/s/v2_c_FI5RYWbdpAtjsy4OIKrKw', {
frames: ['shape:x8z3Qf7Hgw4Qqp2AC-eet'],
})
By default, the Node API only logs warnings and errors. If you want to log the equivalent of the --verbose
flag from the command line version, then you can set a flag on a logging object exported from the library:
// tldraw-cli-api-verbose-test.ts
import { tldrawToImage, log } from '@kitschpatrol/tldraw-cli'
// this will log extra info
log.verbose = true
await tldrawToImage('https://www.tldraw.com/s/v2_c_JsxJk8dag6QsrqExukis4')
// now we'll only log errors and warnings
log.verbose = false
await tldrawToImage('https://www.tldraw.com/s/v2_c_JsxJk8dag6QsrqExukis4')
Mirrors the tldraw open
CLI command.
Caution
Passing a local .tldr file with the location: 'remote'
option will upload and share your sketch on tldraw.com.
async function tldrawOpen(
tldrPathOrUrl?: string,
options?: Partial<{
location: 'local' | 'remote'
}>,
): Promise<{
browserExitPromise: Promise<ChildProcess>
openedSketchUrl: string
}>
It's important to note that the returned result includes browserExitPromise
, which resolves when the user has completely exited the web browser used to open the tldr file or url.
You must await the browserExitPromise
(or somehow keep script's process alive) if you're opening a tldr file with the `location: 'local'`. This prevents the local server from closing prematurely, which would interfere with any server-dependent actions in tldraw.
Example of opening a local file:
import { tldrawOpen } from 'tldraw-cli'
const { browserExitPromise } = await tldrawOpen('./sketch.tldr', {
location: 'local',
})
// Wait for the browser to close to keep
// the local tldraw instance running!
await browserExitPromise
While opening the file remotely on tldraw.com is more casual:
import { tldrawOpen } from 'tldraw-cli'
await tldrawOpen('./sketch.tldr', {
location: 'remote',
})
async function tldrawToShareUrl(tldrPathOrUrl: string): Promise<string>
Returns a live "share" url for a given local or remote tldraw sketch URL.
Caution
Passing a local .tldr file to this function will upload and share your local file to tldraw.com.
If you're working with .tldr files and tldraw-cli
locally, it's often convenient to automatically export image files from your sketches whenever they've changed.
Depending on your workspace and particularly use-cases, there are several approaches that can work well to trigger re-export on change:
The chokidar-cli
tool (which wraps the Chokidar library) makes quick work of this:
npx chokidar-cli "**/*.tldr" -c "npx @kitschpatrol/tldraw-cli export ${path}"
This will watch for changes to .tldr files anywhere in or below the current directory, and then export an SVG every time they change. Pass additional flags to tldraw-cli export
if you need particular export settings.
The tldraw extension for VS Code allows you to edit local .tldr files directly from a tab in your editor. This combines well with the File Watcher extension to trigger re-exports after making edits in a tldraw tab:
Install the extensions (assuming you have code
in your path):
code --install-extension tldraw-org.tldraw-vscode
code --install-extension appulate.filewatcher
Then configure your workspace's .vscode/settings.json
file to include the following:
{
"filewatcher.commands": [
{
"match": "\\.tldr",
"isAsync": true,
"cmd": "cd ${workspaceRoot} && npx @kitschpatrol/tldraw-cli export ${file}",
"event": "onFileChange"
}
]
}
If you're using one of the many Vite-powered web frameworks out there, the @kitschpatrol/vite-plugin-tldraw
plugin can help you treat .tldr as regular importable / linkable assets in your site by automating conversion to a web-friendly format during both development and production builds of your site.
See the plugin's readme for details, but the gist is that it lets you import and use .tldr files as if they were already SVGs:
import tldrFile from './test-sketch.tldr'
document.body.innerHTML = `<img src="${tldrFile}">`
Will render:
<img src="./test-sketch.svg" />
The potential utility of a tldraw CLI app has received mention a few times.
On GitHub:
- [Feature]: CLI export application #1491
- AWS Lambda-based approach
- Added exporting of shapes and pages as images
- [feature] Copy/Share as PNG
On Discord:
This tool is not a part of the official tldraw project.
Due to the architecture of tldraw, export depends on functionality provided by a web browser. So, behind the scenes, this app serves a local instance of tldraw, then loads a .tldr
and invokes the export download via the Puppeteer headless browser automation tool.
This can be a bit slow, (exporting seems to take a second or two), but in the context of a statically-generated content pipeline it's not the end of the world.
In terms of Puppeteer vs. Playwright and other headless browser automation tools, it looks like Puppeteer's performance likely compares favorably. (Though I have not tested and benchmarked the alternatives in the specific context of tldraw-cli
.)
The local instance of tldraw includes its assets dependencies, so the tool should work correctly without internet access.
Track the tldraw changelog.
Eventually, I think it would make sense for some kind of CLI tool like this one to be part of the core tldraw project. (Similar to how tldraw-vscode is currently integrated.)
I'm consciously releasing this tool under the @kitschpatrol
namespace on NPM to leave the tldraw-cli
package name available to the core tldraw project.
Issues and pull requests are welcome.
