Format

The configuration is represented as a JSON (JavaScript Object Notation) string with the following options:

defaultFonts: An array of font family names (String) or custom fonts {“fontFamily”: name, “fontUrl”: url} for the format panel font drop-down list. See below for an example.
customFonts: An array of font family names or custom fonts {“fontFamily”: name, “fontUrl”: url} to be added before defaultFonts (9.2.4 and later). Eg. [“Helvetica”, {“fontFamily”: “Rock Salt”, “fontUrl”: “https://fonts.googleapis.com/css?family=Rock+Salt”}].
Note: Fonts with no fontUrl must be installed on the server and all client devices, or be added using the fontCss option. (6.5.4 and later).
presetColors: Colour codes for the upper palette in the colour dialog (no leading # for the colour codes, null for a blank entry).
customPresetColors: Colour codes to be added before presetColors (no leading # for the colour codes, null for a blank entry) (9.2.5 and later).
defaultColors: Colour codes for the lower palette in the colour dialog (no leading # for the colour codes, null for a blank entry).
colorNames: Names for colors, eg. {‘FFFFFF’: ‘White’, ‘000000’: ‘Black’} that are used as tooltips (uppercase, no leading # for the colour codes).
defaultColorSchemes: Available colour schemes in the style section at the top of the format panel (use leading # for the colour codes). Possible colour keys are fill, stroke, gradient and font (font is ignored for connectors). An optional title can be added to be used as a tooltip. An optional border can be added to define the CSS for the border width and type, eg. ‘2px solid’ or ‘3px dashed’ (only setting the border width is not valid, the border type must be included).
customColorSchemes: Colour schemes to be added before defaultColorSchemes (9.2.4 and later).
defaultVertexStyle or defaultEdgeStyle: Defines the initial default styles for vertices and edges (connectors). Note that the styles defined here are copied to the styles of new cells, for each cell. This means that these values override everything else that is inherited from other styles or themes (which may be supported at a later time). Therefore, it is recommended to use a minimal set of values for the default styles. To find the key/value pairs to be used, set the style in the application and find the key and value via Edit Style (Ctrl+E) (6.5.2 and later).
For example, to assign a default fontFamily of Courier New to all edges and vertices (and override all other default styles), use {"defaultVertexStyle": {"fontFamily": "Courier New"}, "defaultEdgeStyle": {"fontFamily": "Courier New"}}.

styles: Defines an array of objects that contain the colours (fontColor, fillColor, strokeColor and gradientColor) for the Style tab of the format panel if the selection is empty. These objects can have a commonStyle (which is applied to both vertices and edges), vertexStyle (applied to vertices) and edgeStyle (applied to edges), and a graph with background and gridColor. An empty object will apply the default colors.
For example:

[ {},
{
  "commonStyle": {
    "fontColor": "#5C5C5C",
    "strokeColor": "#006658",
    "fillColor": "#21C0A5"
  }
},
{
  "commonStyle": {
    "fontColor": "#095C86",
    "strokeColor": "#AF45ED",
    "fillColor": "#F694C1"
  },
  "edgeStyle": {
    "strokeColor": "#60E696"
  }
},
{
  "commonStyle": {
    "fontColor": "#E4FDE1",
    "strokeColor": "#028090",
    "fillColor": "#F45B69"
  },
  "graph": {
    "background": "#114B5F",
    "gridColor": "#0B3240"
  }
}
]

defaultLibraries: Defines a semicolon-separated list of library keys (unique names) in a string to be initially displayed in the left panel (e.g. "general;uml;company-graphics"). Possible keys include custom entry IDs from the libraries field, or keys for the libs URL parameter (6.5.2 and later). The default value is "general;uml;er;bpmn;flowchart;basic;arrows2".
enabledLibraries: Defines an array of strings of library keys which will be available in the More Shapes dialog. If you define this as null, all libraries will be visible. If you leave the array empty, no libraries will be visible (e.g. ["general", "uml"]) (9.2.5 and later).
libraries: Defines an array of objects that list additional libraries and sections in the left panel and the More Shapes dialog, in the following format: [section1,...,sectionN]. Where:
- each section has the form {title: resource, entries: [entry1,...,entryN]}.
- each entry has the form {id: string, preview: string, title: resource, desc: resource, libs: [lib1,..,libN]}.
- each lib has the form {title: resource, url: string OR data: string, tags: string}.
  - sections are used for the sections in the More Shapes dialog.
  - entries are the entries for the sections and each entry may have one or more libraries associated. The id of each entry must be unique, preview is the URL of an image to be used as a preview and desc is used before or in place of the review as a description (pre-formatted text which supports linefeeds).
  - In libs, resource is a language resource defined as {main: string, xy: string} where xy may be any country code (e.g. es, fr, de) and where main is the fallback if no string is defined for the current country code (i.e. the default resource).
  - Also in libs, tags is an optional string with a space-separated list of searchable tags.
  - libs may use an external resource via the URL in the url field or define the library entries directly via data, which contains the array between <mxlibrary>...</mxlibrary> in the library files. By default, all entries with data and the first 20 entries with url are prefetched and added to the search index. To prefetch additional entries with url, add "prefetch": true to the respective lib (9.2.5 and later).
    For example:
    [ { "title": { "main": "Company" }, "entries": [ { "id": "company-graphics", "title": { "main": "Graphics", "de": "Grafiken" }, "desc": { "main": "Collection of Graphics for Company", "de": "Sammlung von Grafiken für Firma" }, "libs": [ { "title": { "main": "Graphics for Company", "de": "Grafiken für Firma" }, "data": [ { "xml": "jZLBbsMgDIafhmuUgKr1mqZbL5u0VyCJF5BMHIHbpG9fEti6Tqq0A5L5/NuYH4Rq3HLyejIf1AMK9SpU44k4RW5pAFHI0vZCHYWUZVxCvj3JVlu2nLSHkf9TIFPBReMZEkkg8BUz6HUwsMpLoQ50ZrQjNDSO0HGGhl0c/FjFUKMdxhh38XzwEaBuAT8pWLb0kLiAZ9tpfP8jaImZ3C9BnVsyTZEGo6d1MLcMq2nFDC3SQKHovZ4tySj5sogNIfltflXVu0Ot8j1jT1ieerWhbNQJyAH7a5TMtmeTFDtZZIcM2MHkupey2CeqQyLDT/Xd/Bhk/7+393fecg/f4AY=", "w": 52.2, "h": 70.8, "aspect": "fixed" } ] } ] } ] } ]
    This configuration produces the following More Shapes dialog when combined with enabledLibraries: []:
defaultCustomLibraries: Defines an array of IDs to load custom libraries.
- In Atlassian Confluence, define the IDs as A1...An, e.g. {"defaultCustomLibraries": ["A1"]}. To get the ID for a custom library, move the mouse over the entry in the Select Library dialog or the title of the library in the left panel and wait for the tooltip to appear, e.g. my library (A1), where A1 is the ID. If no tooltip appears, open the library in a diagram, save the diagram, then refer to the <mxAtlasLibraries> section in the diagram file attached to the page that uses the diagram name, but is not the .png file extension (6.5.2 and later).
- Alternatively, you can use an ID that is the UencodedURI to load a library from an URL, e.g. {"defaultCustomLibraries": ["U%2Fconfluence%2Fdownload%2Fattachments%2F720900%2FScratchpad.xml%3Fapi%3Dv2"]}
  Note: To encode a URL, enter the URL into our URL encode tool and select URL Encode.
- To load the libraries from the libraries section above, use the defaultLibraries setting.
enableCustomLibraries: Specifies if the open and new library functions are enabled (true or false, the default is true).
appendCustomLibraries: Specifies if custom libraries should appear after built-in libraries (true or false, the default is false) (22.1.7 and later).
expandLibraries: Specifies if libraries are expanded by default (true or false, the default is true) (22.1.6 and later).
templateFile: Defines the URL of the source file for the Templates dialog (multiple <template> and <clibs> tags are allowed). Example
css: Defines a string with CSS rules to be used to configure the draw.io user interface. For example, to change the background colour of the menu bar, use the following: {"css": ".geMenubarContainer { background-color: #c0c0c0 !important; } .geMenubar { background-color: #c0c0c0 !important; }"} (6.5.2 and later).
fontCss: Defines a string with CSS rules for web fonts to be used in diagrams. This should be one or more @font-face rule, e.g. to use a font file attached to a Confluence page: {"fontCss": "@font-face { font-family: 'Marvel'; src: url(/confluence/download/attachments/720900/Marvel-Regular.ttf?api=v2) format('truetype')}"}
The fonts in this section are used for displaying diagrams in the editor and creating images in Google Chrome, Firefox and Microsoft Edge. All other browsers require the font to be installed on the server-side.
Confluence Server and Data Center: To create images in the browser, the font must be on the same domain and contain a CORS header, or it will be proxied via the Confluence server.
Confluence Cloud: The font URL must be public and must allow access to the draw.io origin (CORS header):
"fontCss": "@font-face { font-family: 'Waltograph'; src: url(https://fontlibrary.org/assets/fonts/waltograph/23a40698cd1bb84f930b7a0884c134a6/ab260a56f2b852b78f81eac337e0a2fc/WaltographRegular.otf) format('opentype')}" and "customFonts": ["Waltograph”]
Note: All fonts will be downloaded to the client when they create an image and save the diagram, so the number of custom fonts should be kept to a minimum. The external image service does currently not support custom fonts.

selectParentLayer: true - Selects the parent layer for the current selection (22.1.4 and later). Default is false.
defaultEdgeLength: Defines the default length for new connectors (7.2.4 and later).
defaultPageVisible: Defines whether the page is initially visible (true/false).
defaultGridEnabled: Defines whether the grid is initially enabled (true/false).
autosaveDelay: Defines the delay (in ms) between the last change and the autosave of the file (10.4.7 and later).
version: The current version of the configuration (any string, e.g. "1.0"). If this is different from the last used version, then the current settings on the client-side (.drawio-config) will be reset. The default is null. Change this to force the stored settings in the client to be reset and apply the current configuration (7.2.8 and later).
override: Ignores the current settings on the client-side if this is set to true (9.2.5 and later).
globalVars: Defines global variables for system-wide placeholders using a JSON structure with key, value pairs. Keep the number of global variables small.
compressXml: Specifies if the XML output should be compressed. The default is false.
includeDiagram: Specifies the default for including diagram data in export dialogs (15.0.4 and later).
lockdown: Disable data transmission, apart from directly between your browser and your selected data storage location. Default is false.
restrictExport: Disable exporting diagram to other formats, this doesn’t prevent users from being able to obtain text or image formats of the diagram, but makes it somewhat harder. Default is false.

The configuration of the online version is stored in your browser in local storage under the key .configuration.
The draw.io configuration is stored in your browser's local storage

The current settings of the editor (such as the recent colours, current open libraries, etc.) persist in your browser in local storage under the key .drawio-config:
Current settings for draw.io are saved in local storage in your browser

You can add defaultEdgeLength and autosaveDelay directly to .drawio-config to override the default values for the web app in your browser.

Delete the current settings or configuration

Open the Google Chrome Developer Tools: More Tools > Developer Tools.
Go to the Application tab, and select Storage > Local Storage > your_domain_name.
Right click on and delete .drawio-config in the Key-Value table.

Fixing errors in your configuration

If the configuration has an invalid format, a configuration error is shown in the Chrome Console tab when the diagram editor opens. Replace double-escaped quotes (\”) with single-escaped quotes ("), to ensure the configuration is valid JSON and can be checked with a validator such as JSONLint.

Configuring the online app

You can create a link to configure the online version of draw.io by clicking on Link in the Configuration dialog: Click on Help > Configuration.

Note: If you need to support Microsoft Edge or IE11 then you’ll need to stay under 2,025 character hashes.
