@startDocuBlock api_foxx_service_replace @brief replace a service

@RESTHEADER{PUT /_api/foxx/service, Replace service}

@RESTDESCRIPTION Removes the service at the given mount path from the database and file system. Then installs the given new service at the same mount path.

This is a slightly safer equivalent to performing an uninstall of the old service followed by installing the new service. The new service's main and script files (if any) will be checked for basic syntax errors before the old service is removed.

The request body can be any of the following formats:

• application/zip: a raw zip bundle containing a service
• application/javascript: a standalone JavaScript file
• application/json: a service definition as JSON
• multipart/form-data: a service definition as a multipart form

A service definition is an object or form with the following properties or fields:

• configuration: a JSON object describing configuration values
• dependencies: a JSON object describing dependency settings
• source: a fully qualified URL or an absolute path on the server's file system

When using multipart data, the source field can also alternatively be a file field containing either a zip bundle or a standalone JavaScript file.

When using a standalone JavaScript file the given file will be executed to define our service's HTTP endpoints. It is the same which would be defined in the field main of the service manifest.

If source is a URL, the URL must be reachable from the server. If source is a file system path, the path will be resolved on the server. In either case the path or URL is expected to resolve to a zip bundle, JavaScript file or (in case of a file system path) directory.

Note that when using file system paths in a cluster with multiple coordinators the file system path must resolve to equivalent files on every coordinator.

@RESTQUERYPARAMETERS

@RESTQUERYPARAM{mount,string,required} Mount path of the installed service.

@RESTQUERYPARAM{teardown,boolean,optional} Set to false to not run the old service's teardown script.

@RESTQUERYPARAM{legacy,boolean,optional} Set to true to install the new service in 2.8 legacy compatibility mode.

@RESTQUERYPARAM{force,boolean,optional} Set to true to force service install even if no service is installed under given mount.
