Thinking of contributing to iD? High five! There are plenty of ways to get involved. You don't need to know anything about programming (though it's always a great time to learn!).
Everyone involved in the iD project is subject to the Code of Conduct. Please take a moment to read it before proceeding, it's short and simple. We want everyone to feel comfortable contributing to iD.
We'd love to hear your feedback about iD. Please search existing issues before opening a new one. Many bugs and ideas have already been posted.
When reporting a bug:
- Write specifically what browser (type and version, like "Firefox 49.0"), OS, and browser extensions you have installed
- Write steps to replicate the error: when did it happen? What did you expect to happen? What happened instead?
- We love screenshots. If you can take a picture of the issue, that is extra helpful. You can drag the image or video file onto the GitHub issue and it will be included with your bug report.
- Please keep bug reports professional and straightforward: trust us, we share your dismay at software breaking.
- If you can, enable web developer extensions and report the JavaScript error message.
- When in doubt, over-describe the bug and how you discovered it.
When requesting a feature:
- Provide a link if the feature is available in some other software. We care about prior art.
- Understand that iD is focused on simplicity and doesn't aim to be as complete as JOSM or other editors.
We use GitHub labels to keep track of issues. Some guidelines:
Green labels are for action items. Jump in and start working!
- - Best for new contributors. No experience necessary!
- - For more intermediate contributors, probably requires investigation or knowledge of iD code.
- -
Issues that have a big impact or matter most to new mappers.
(There should probably be 10 or fewer "priority" items.)
Red labels are for bugs. These are things that we want fixed, but might be a bit more complicated than the green action items.
Purple labels are for non-action items. These might be a question or feature request that needs some discussion about whether it belongs in iD. Discuss before working on these.
Yellow labels are for chores. These are the things like code cleanup, upgrades, tests, documentation, repository gardening, and other stuff that makes developers happy.
Light blue labels are for components, the specific parts of iD that concern the issue.
Dark teal labels are for categories, the high-level concepts that the issue falls under.
Dark grey labels are for waitfor items. We won't work on these now, but we'll keep the issues open while we wait for something to happen.
Light grey labels are for wontfix items. We've decided these doesn't belong in iD at this time. Don't feel bad, sometimes we change our minds later and revisit them!
Special:
- - Bluesky issues are extra challenging. They might require weeks of development or not even be possible.
- - Work in Progress. Don't start work on these, somebody else already did!
You can use the development preview site to test
unreleased features and verify bug fixes, all without building iD yourself. This site
is updated with the latest code and translations every time we change the develop
branch.
The deployments on https://openstreetmap.org and https://ideditor-release.netlify.app are updated only with stable releases. Recently fixed issues may still be present on these sites until the next version of iD is released.
While it's possible to edit the live OpenStreetMap database with development versions of iD, it's risky to do so. Your edits could be lost or garbled at any time. Press the button in the bottom bar to switch to the development database.
Translations are managed using the Transifex platform. After signing up, you can go to iD's project page, select a language and click Translate to start translating. Translations are divided into separate resources:
- core - contains text for the main interface of iD
- presets - contains the text for labeling feature presets
- imagery - contains text for imagery names and descriptions
The words in brackets, for example {name}
, should not be translated into a
new language: it's replaced with a place name when iD presents the text. So a
French translation of Couldn't locate a place named '{name}'
would look like
Impossible de localiser l'endroit nommé '{name}'
.
The translations for presets, maintained in the id-tagging-schema repository, consist of the names of presets, labels for preset fields, and lists of search terms. You do not need to translate the search terms literally -- use a set of synonyms and related terms appropriate to the target language, separated by commas. For more information on translating the presets please see this id-tagging-schema contribution guide.
You can check your translations on the development preview site,
which is updated every time we change the develop
branch.
iD translation project on Transifex
To get notifications when translation source files change, click Watch project button near the bottom of the project page. You can edit your notification settings if you're getting too many notifications.
Translations are licensed under ISC, the same license as iD.
Why are there so many duplicate "Type" translations? There are multiple distinct preset fields with the label "Type". You can see some context on the "Details" tab in Transifex:
The "key" field indicates that this is the "Type" label for the "aeroway" preset, i.e. you should translate it as you would translate "type" in "type of aeroway".
These are separate translations for uniformity reasons and because some languages may translate "type" differently in "type of aeroway" and "type of amenity", for example.
Why can't I find the Osmose QA layer translations? The Osmose QA strings are pulled in from the external Osmose API. You can contribute to the Osmose Transifex project and the results will be seen in iD once deployed.
Note that if you want to add/update English translations in Osmose then you will need to head on over to the Osmose backend source code.
iD translates strings with a t
function: t('foo.bar')
translates the key
foo.bar
into the current language. If you introduce new translatable strings,
only display them in the interface through the t()
function.
Then, add the new string to data/core.yaml
. The translation system, Transifex,
will automatically detect the change.
If you are updating an existing string, update it in data/core.yaml
and run
npm run build
to generate the en.json
file automatically, then commit both
modified files.
Use npm run build
to build the translations with the local changes.
npm run translations
can be used to pull the latest translations from Transifex.
Documentation is maintained as a series of Markdown
documents in core.yaml. The documentation
is in the help
section. The first line
of each new section of documentation should be of the form
# GPS
This will be used for navigation and as its title in iD. To add a new piece
of documentation, simply add to /data/core.yaml in the
same format as the rest, include your new corresponding docKey
in
/modules/ui/help.js and call npm run build
.
iD's knowledge of OpenStreetMap tags is mostly handled by the iD Tagging Schema project, which has its own opportunities to contribute.
We like when people get involved! iD is a busy project, so it helps if you first open an issue to ask whether an idea makes sense, instead of surprising us with a pull request.
iD code was initially written with ES5 syntax, however we do now develop using ES6 syntax.
We mostly follow the Airbnb style guide for JavaScript:
We ask that you follow the convention of using 4 space indent in ES5 files and 2 space indent in ES6 files. While the indenting doesn't matter to the compiler, it does make it easier for us humans to see at a glance whether a file has been "upgraded" to ES6.
Always spaces, never tabs.
JavaScript code should pass through ESLint with no warnings.
There isn't much HTML in iD, but what there is is similar to JavaScript: 4 spaces always, indented by the level of the tree:
<div>
<div></div>
</div>
Just like HTML and JavaScript, 4 space soft tabs always.
.menu-tooltip {
background: rgba(255, 255, 255, 0.8);
}
We write vanilla CSS with no preprocessing step. Since iD targets modern browsers, (Chrome, Firefox, Safari, Opera, and Edge) feel free to use newer features wisely.
Test your code and make sure it passes.
- Go to the directory where you have checked out
iD
- run
npm install
- run
npm test
to see whether your tests pass or fail.
Note that in order to run the tests, Chrome needs to be installed on the system. Chromium can be used as an alternative, but requires setting the environment variable CHROME_BIN
to the corresponding executable (e.g. export CHROME_BIN="
which chromium"
).
Follow the steps in the how to get started guide on how to build and run iD.
iD is available under the ISC License. Some of the libraries it uses are under different licenses. If you're contributing to iD, you're contributing ISC Licensed code.

If you are new to GitHub or git you can read the GitHub Guides "Understanding the GitHub Flow", "Git Handbook" and "Forking Projects" could be especially interesting to you.
Additionally here is a step-by-step workflow example for beginners:
-
Login to your GitHub account or create a GitHub account, if you do not already have one.
-
Go to the iD main repository and fork iD into your GitHub account (Fork is top right).
-
Set up Git and prepare for Authenticating with GitHub from Git.
-
Clone or download your local copy of iD from your GitHub account using https
git clone https://github.com/<yourgithubaccount>/iD.git
or using sshgit clone [email protected]:{{yourgithubaccount}}/iD.git
. In your local copy you'll have a "remote" called origin. -
Switch to the iD directory, create a working branch (choose a descriptive name) and switch to it :
cd iD ; git checkout -b <working-branch-name>
. Never do anything in thedevelop
branch. -
Edit file(s) and try your change locally (See above).
-
Add Files and commit them
git add <files> ; git commit -m "Description of what you did"
.. repeat as needed .. -
Push Changes to your GitHub account
git push origin <working-branch-name>
. The next push also works without the branch name:git push origin
. -
Go to GitHub for your fork of iD at https://github.com/{{yourgithubaccount}}/iD. GitHub will already know about your recently pushed branch, and ask if you want to create a Pull Request for it.
-
Your Pull Request will be seen by the maintainers of iD. They can merge it or ask for changes. You can update your Pull Request with Steps 7 and 8, Step 9 is required only once per Pull Request.
After your Pull Request gets merged into the main repository you can clean up by deleting the branch from your GitHub-iD-Clone and your local directory
git push --delete origin <working-branch-name> ; git branch -d <working-branch-name>
If you did not use your copy of iD for some while, other Pull Request gets merged and you don't have the latest version of iD. You can replace your develop
with whatever is in our develop
. If you have not done so yet: Add the main repo as an "upstream" remote:
git remote add upstream [email protected]:openstreetmap/iD.git
Then change to the develop
branch and get everything from upstream (the main repository)
git checkout develop ; git fetch --all && git reset --hard upstream/develop
If you want to submit Documentation, Spelling improvements, etc. which do not need testing, you can do this with your browser in GitHub. Please don't use this to change Code and create untested Pull Requests. You also need a GitHub account and may find this Article about Editing and this Article about Pull Requests useful.
Additionally here is a step-by-step workflow example for beginners:
-
Login to your GitHub account or create a GitHub account, if you do not already have one.
-
Go to the iD main repository and fork iD into your GitHub account (Fork is top right).
-
Create a New Branch by clicking on "Branch: develop" and entering the name of a new branch (choose a descriptive name).
-
Navigate to the file you want to edit and click on "Edit this file" and apply your changes to the file. Alternatively, you could also "Create a new file".
-
When finished editing the file enter a commit text (the description is optional) and commit directly to the newly created branch. You may repeat 4 and 5 until all required changes are committed.
-
Navigate back to your "id" project - https://github.com/{{yourgithubaccount}}/iD
