jivan (जीवन) Build Status

jivan is a Go server implementation of OGC WFS 3.0.


This project provides a straightforward and simple way to publish your geospatial data on the web. jivan currently supports GeoPackage and PostGIS backends. Providers implement a straightforward interface so others can be added fairly easily.


  • The simplest way to start is to simply put a GeoPackage file in the same directory as the executable and run it.

  • You can provide the connection details for the data backend and the provider will scan your data collection and publish any tables with geographical data each as a separate collection. Support to customize the data published, including collections based on SQL are a short coding effort away.

  • You can also provide a config file. Configuration support is in a fairly early state. Take a look at jivan-config.toml for an example, and keep in mind::

    • Currently the [logging] section is not used
    • From the [metadata] section, only the following are currently used:
      • title
      • description
    • In the [server] section, only the following are currently used:
      • bind_host
      • bind_port
      • url_scheme
      • url_hostport
      • url_basepath
      • default_mimetype
      • paging_maxlimit

GeoPackage Example: jivan -d /path/to/my.gpkg

PostGIS Example: jivan -d ' port=5432 dbname=mydbname user=myuser password=mypassword'

Then visit to view your data as a wfs3 service.

jivan provides a number of handy flags to customize where it binds and the links it generates in results to make it simple for sysadmins to, for example, deploy behind a proxy. Run jivan --help for details.

See jivan-config.toml TODO: TOML configuration files

Currently supported TOML:

  • config.Configuration.Server.DefaultMimeType
  • config.Configuration.Server.MaxLimit

Bugs and Issues

All bug reports, enhancement requests, and other issues are managed on GitHub.

Developer Notes

for further details see the README in each folder

  • config/ Responsible for dealing with configuration files & providing the parameters from a config to the rest of the system.

  • server/ Responsible for the actual server and all html traffic specific tasks such as determining content encoding and collecting url query parameters.

  • wfs3/ Responsible for wfs3-specific details such as go versions of wfs3 types and collecting appropriate data for each wfs3 endpoint. The types here implement the supported encodings.

  • data_provider/ Responsible for access to data backends. Essentially a wrapper with some functionality added for tegola data providers

  • main.go Executable entry-point.

Visit http://localhost:9000/api for OpenAPI definition of the service. Take a look at server/routes.go for a concise list of supported URLs.

Build Instructions

# create directory for local env
mkdir /path/to/golang-env
export GOPATH=/path/to/golang-env
# install jivan
go get
# install 'dep' dependency manager
go get
# install dependencies in vendor/
dep ensure
go build -i -o jivan

To build for AWS Lambda deployments, add -tags awslambda when building


# start server on http://localhost:9000/
go run main.go  # or go build main.go


dep ensure will install dependencies at the current HEAD when you run it (equivalent to go get ...)

Run dep ensure -update periodically to stay current with these dependencies. (equivalent to subsequent go get ...)

Please don't add Gopkg.lock to the repo.
