Moov's mission is to give developers an easy way to create and integrate bank processing into their own software products. Our open source projects are each focused on solving a single responsibility in financial services and designed around performance, scalability, and ease of use.
Wire implements a reader, writer, and validator for FED Wire Messages (FEDWire) in an HTTP server and Go library. The HTTP server is available in a Docker image and the Go package github.com/moov-io/wire is available.

Moov Wire is actively used in multiple production environments. Please star the project if you are interested in its progress. If you have layers above Wire to simplify tasks, perform business operations, or found bugs we would appreciate an issue or pull request. Thanks!
The Wire project implements an HTTP server and Go library for creating and modifying Wire files. We also have some examples of the reader and writer.
We publish a public Docker image moov/wire on Docker Hub with every tagged release of Wire. No configuration is required to serve on :8088 and metrics at :9098/metrics in Prometheus format. We also have Docker images for OpenShift published as quay.io/moov/wire.
Pull & start the Docker image:
docker pull moov/wire:latest
docker run -p 8088:8088 -p 9098:9098 moov/wire:latest
List files stored in-memory:
curl localhost:8088/files
null
Create a file on the HTTP server:
curl -X POST --data-binary "@./test/testdata/fedWireMessage-CustomerTransfer.txt" http://localhost:8088/files/create
{"id":"<YOUR-UNIQUE-FILE-ID>","fedWireMessage":{"id":"","senderSupplied":{"formatVersion":"30", .....
Get the file in its original format:
curl http://localhost:8088/files/<YOUR-UNIQUE-FILE-ID>/contents
{1500}30User ReqT
{1510}1000
{1520}20190410Source08000001
...
To get started in a hosted environment you can deploy this project to the Google Cloud Platform.
From your Google Cloud dashboard create a new project and call it:
moov-wire-demo
Enable the Container Registry API for your project and associate a billing account if needed. Then, open the Cloud Shell terminal and run the following Docker commands, substituting your unique project ID:
docker pull moov/wire
docker tag moov/wire gcr.io/<PROJECT-ID>/wire
docker push gcr.io/<PROJECT-ID>/wire
Deploy the container to Cloud Run:
gcloud run deploy --image gcr.io/<PROJECT-ID>/wire --port 8088
Select your target platform to 1, service name to wire, and region to the one closest to you (enable Google API service if a prompt appears). Upon a successful build you will be given a URL where the API has been deployed:
https://YOUR-WIRE-APP-URL.a.run.app
Now you can list files stored in-memory:
curl https://YOUR-WIRE-APP-URL.a.run.app/files
You should get this response:
null
The following environmental variables can be set to configure behavior in Wire.
| Environmental Variable | Description | Default |
|---|---|---|
HTTPS_CERT_FILE |
Filepath containing a certificate (or intermediate chain) to be served by the HTTP server. Requires all traffic be over secure HTTP. | Empty |
HTTPS_KEY_FILE |
Filepath of a private key matching the leaf certificate from HTTPS_CERT_FILE. |
Empty |
WIRE_FILE_TTL |
Time to live (TTL) for *wire.File objects stored in the in-memory repository. |
0 = No TTL / Never delete files (Example: 240m) |
By design, Wire does not persist (save) any data about the files or entry details created. The only storage occurs in memory of the process and upon restart Wire will have no files or data saved. Also, no in-memory encryption of the data is performed.
This project uses Go Modules and Go v1.18 or newer. See Golang's install instructions for help setting up Go. You can download the source code and we offer tagged and released versions as well. We highly recommend you use a tagged release for production.

Using our in-browser utility, you can instantly convert Wire files into JSON. Either paste in Wire file content directly or choose a file from your local machine. This tool is particulary useful if you're handling sensitive PII or want perform some quick tests, as operations are fully client-side with nothing stored in memory. We plan to support bidirectional conversion in the future.

This project uses Go Modules and Go v1.18 or newer. See Golang's install instructions for help setting up Go. You can download the source code and we offer tagged and released versions as well. We highly recommend you use a tagged release for production.
To make a release of wire simply open a pull request with CHANGELOG.md and version.go updated with the next version number and details. You'll also need to push the tag (i.e. git push origin v1.0.0) to origin in order for CI to make the release.
We maintain a comprehensive suite of unit tests and recommend table-driven testing when a particular function warrants several very similar test cases. To run all test files in the current directory, use go test. Current overall coverage can be found on Codecov.
We currently run fuzzing over Wire in the form of a Github Action. Please report crashes examples to oss@moov.io. Thanks!
