@ -45,12 +45,20 @@ For building from source, you can start with this:
npm install
npm run build:prod
npm run install:python
GRIST_DEFAULT_EMAIL=you@example.com npm start
npm start
# unauthenticated grist api available at http://localhost:8484/api/
Stay tuned for more instructions to come at release.
Then you can use the Grist API locally to work on a document. Currently you need
to "upload" a document to work with it. This makes a copy of it that the server
controls - you can find it in the `data` directory:
For using pre-built Grist, just head on over to <https://www.getgrist.com>.
curl -F 'upload=@YourDocument.grist' http://localhost:8484/api/docs
# Note the document ID that is returned.
The [Data-Tables endpoints](https://support.getgrist.com/api/#tag/Data-Tables) are
particularly useful.
For using hosted Grist, just head on over to <https://www.getgrist.com>.
