io-sign is the IO platform feature that allows citizens to sign digitally documents and contracts sent by public administration.

This repository contains the code that composes the io-sign back-end, that is organized into two microservices:

1. io-func-sign-issuer that exposes the API used by public entities
2. io-func-sign-user that exposes the ReST API consumed by the IO mobile app

These services are deployed as Azure Function App, and use the Node.js Azure runtime.

It also contains io-sign-selfcare-frontend the frontend for self-care integration.

In order to run the io-sign back-end/front-end locally you need the following tool installed on your machine.

• Node.js 16
• yarn 3

The preferred way to set up the local environment is using nodenv to manage Node.js installation and corepack (included with Node.js) to manage the installation of yarn.

To test the Azure Functions locally:

1. Setup the Environment Variables. Create a file called local.settings.json in each Azure Functions App folder (./apps/*) valued according to the environment variables listed in local.settings.json.example.

2. Install the project. Run from the root folder the following commands.

# to install the dependencies
yarn
# to generate the TypeScript models based on OpenAPI specs
yarn workspaces foreach run generate:api-models
# to build all projects
yarn build

To test the webapp locally:

1. Install the project (if you haven't already). Run from the root folder the following commands.

# to install the dependencies
yarn
# to build all projects
yarn build

2. Run the Web App. Run (from the root folder) the following command

yarn workspace io-sign-selfcare-frontend dev

This project uses changesets to automate updating package versions, and changelogs.

Each Pull Request that includes changes that require a version bump should include a changeset file that describe that changes.

To create a new changeset file run the following command from the project root:

yarn changeset

This project uses yarn@3 with workspaces to manage projects and dependencies. Here is a list of useful commands to work in this repo.

# to execute COMMAND on WORKSPACE_NAME
yarn workspace WORKSPACE_NAME run command
# to execute COMMAD on all workspaces
yarn workspace foreach run command

# run unit tests on @io-sign/io-sign
yarn workspace @io-sign/io-sign run test

# run the typecheck script on all workspaces
yarn workspaces foreach run typecheck

# generate the API models for all workspaces
yarn workspaces foreach run generate:api-models

# add a dependency to the workspace root
yarn add turbo

# add a jest as dev dependency on @io-sign/io-sign
yarn workspace @io-sign/io-sign add -D jest

# add io-ts as dependency on each workspace
yarn workspace foreach add io-ts

This command generates a deployment package (ZIP), in the workspace folder, with bundled dependencies, ready to be deployed on Azure.

yarn workspace WORKSPACE_NAME run build:package

# example
yarn workspace io-func-sign-issuer run build:package

This command generates static frontend files inside the out folder which can then be uploaded to a static website:

yarn workspace io-sign-selfcare-frontend run export
