HTTP interface for Foxx
The HTTP API for Foxx allows you to manipulate Foxx microservices installed in a database
For more information on Foxx and its JavaScript APIs see the Foxx documentation.
Management
List the installed services
Fetches a list of services installed in the current database.
Returns a list of objects with the following attributes:
mount
: the mount path of the servicedevelopment
:true
if the service is running in development modelegacy
:true
if the service is running in 2.8 legacy compatibility modeprovides
: the service manifest’sprovides
value or an empty object
Additionally the object may contain the following attributes if they have been set on the manifest:
name
: a string identifying the service typeversion
: a semver-compatible version string
Get the service description
Fetches detailed information for the service at the given mount path.
Returns an object with the following attributes:
mount
: the mount path of the servicepath
: the local file system path of the servicedevelopment
:true
if the service is running in development modelegacy
:true
if the service is running in 2.8 legacy compatibility modemanifest
: the normalized JSON manifest of the service
Additionally the object may contain the following attributes if they have been set on the manifest:
name
: a string identifying the service typeversion
: a semver-compatible version string
Install a new service
Installs the given new service at the given mount path.
The request body can be any of the following formats:
application/zip
: a raw zip bundle containing a serviceapplication/javascript
: a standalone JavaScript fileapplication/json
: a service definition as JSONmultipart/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 valuesdependencies
: a JSON object describing dependency settingssource
: 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.
Uninstall a service
Removes the service at the given mount path from the database and file system.
Returns an empty response on success.
Replace a service
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 serviceapplication/javascript
: a standalone JavaScript fileapplication/json
: a service definition as JSONmultipart/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 valuesdependencies
: a JSON object describing dependency settingssource
: 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.
Upgrade a service
Installs the given new service on top of the service currently installed at the given mount path. This is only recommended for switching between different versions of the same service.
Unlike replacing a service, upgrading a service retains the old service’s configuration and dependencies (if any) and should therefore only be used to migrate an existing service to a newer or equivalent service.
The request body can be any of the following formats:
application/zip
: a raw zip bundle containing a serviceapplication/javascript
: a standalone JavaScript fileapplication/json
: a service definition as JSONmultipart/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 valuesdependencies
: a JSON object describing dependency settingssource
: 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.
Configuration
Get the configuration options
Fetches the current configuration for the service at the given mount path.
Returns an object mapping the configuration option names to their definitions
including a human-friendly title
and the current
value (if any).
Update the configuration options
Replaces the given service’s configuration.
Returns an object mapping all configuration option names to their new values.
Replace the configuration options
Replaces the given service’s configuration completely.
Returns an object mapping all configuration option names to their new values.
Get the dependency options
Fetches the current dependencies for service at the given mount path.
Returns an object mapping the dependency names to their definitions
including a human-friendly title
and the current
mount path (if any).
Update the dependency options
Replaces the given service’s dependencies.
Returns an object mapping all dependency names to their new mount paths.
Replace the dependency options
Replaces the given service’s dependencies completely.
Returns an object mapping all dependency names to their new mount paths.
Miscellaneous
List the service scripts
Fetches a list of the scripts defined by the service.
Returns an object mapping the raw script names to human-friendly names.
Run a service script
Runs the given script for the service at the given mount path.
Returns the exports of the script, if any.
Run the service tests
Runs the tests for the service at the given mount path and returns the results.
Supported test reporters are:
default
: a simple list of test casessuite
: an object of test cases nested in suitesstream
: a raw stream of test resultsxunit
: an XUnit/JUnit compatible structuretap
: a raw TAP compatible stream
The Accept
request header can be used to further control the response format:
When using the stream
reporter application/x-ldjson
will result
in the response body being formatted as a newline-delimited JSON stream.
When using the tap
reporter text/plain
or text/*
will result
in the response body being formatted as a plain text TAP report.
When using the xunit
reporter application/xml
or text/xml
will result
in the response body being formatted as XML instead of JSONML.
Otherwise the response body will be formatted as non-prettyprinted JSON.
Enable the development mode
Puts the service into development mode.
While the service is running in development mode the service will be reloaded from the filesystem and its setup script (if any) will be re-executed every time the service handles a request.
When running ArangoDB in a cluster with multiple Coordinators note that changes to the filesystem on one Coordinator will not be reflected across the other Coordinators. This means you should treat your Coordinators as inconsistent as long as any service is running in development mode.
Disable the development mode
Puts the service at the given mount path into production mode.
When running ArangoDB in a cluster with multiple Coordinators this will replace the service on all other Coordinators with the version on this Coordinator.
Get the service README
Get the Swagger description
Fetches the Swagger API description for the service at the given mount path.
The response body will be an OpenAPI 2.0 compatible JSON description of the service API.
Download a service bundle
Downloads a zip bundle of the service directory.
When development mode is enabled, this always creates a new bundle.
Otherwise the bundle will represent the version of a service that is installed on that ArangoDB instance.
Commit the local service state
Commits the local service state of the Coordinator to the database.
This can be used to resolve service conflicts between Coordinators that cannot be fixed automatically due to missing data.
