Architecture

Git Policies, Activities and Notes

Serverless Name Requirements: A service name should only contain alphanumeric characters (case sensitive) and hyphens. The should start with an alphanumeric character and shouldn't exceed 128 characters.

Please push your code to a new branch with a name that meets the Serverless Name Requirements above. Any other variations and the GitHub Actions will fail.

After creating a branch, if you need to rename it because it does not follow the rules above, use

git branch -m <new-branch-name> to rename your local branch then

git push origin -u <new-branch-name> to rename your remote branch in GitHub.

This project uses a combination of Gitflow and Serverless naming to handle branches and merging. Branches should be prefixed with the type followed by a descriptive name for the branch. For example:

• master > feature-my-feature-name
• master > bugfix-my-bugfix-name
• master > hotfix-my-hotfix-name

On each PR, a linter and prettier check runs. These checks must pass for a PR to be merged. Prior to submitting your PR, run the linter and prettier against the work you have done.

• Run Eslint using yarn lint
• Run Prettier using npx prettier --write .

Local Dev

If you don't have yarn, nvm, or java installed, see Requirements

Get the correct info for the .env file from another developer or copy the env_example to a .env and update it with the appropriate values.

From the root directory run:

nvm use

yarn install

cd services/ui-src

yarn install

cd ../../

./dev local

See the Requirements section if the command asks for any prerequisites you don't have installed.

Local dev is configured in typescript project in src/. The entrypoint is src/dev.ts, it manages running the moving pieces locally: the API, the database, the file storage, and the frontend.

Local dev is built around the Serverless plugin serverless-offline. This plugin runs an API gateway locally configured by ./services/app-api/serverless.yml and hot reloads your lambdas on every file save. The plugins serverless-dynamodb-local and serverless-s3-local stand up the local Database and S3 buckets in a similar fashion.

Local authentication bypasses Cognito. The frontend mimics login in local storage with a mock user and sends an id in the cognito-identity-id header on every request. serverless-offline expects that and sets it as the cognitoId in the requestContext for your lambdas, just like Cognito would in AWS.

Logging in

(Make sure you've finished setting up the project locally above before moving on to this step!)

Once you've run ./dev local you'll find yourself on a login page at localhost:3000. For local development there is a list of users that can be found at services/ui-auth/libs/users.json. That's where you can grab an email to fill in.

For a password to that user, please ask a fellow developer.

Adding New Endpoints

1. In services/app-api/serverless.yml, add a new entry to functions describing the new endpoint. Make sure your http method is set correctly. For example:

functions:
    getUsers:
        handler: handlers/users/list.main
        role: LambdaApiRole
        events:
        - http:
            path: users
            method: get
            cors: true
            authorizer: ${self:custom.authValue.${self:custom.stage}, ""}

2. Create a handler in services/app-api/handlers
   1. Note: For Table names use the custom variables located in services/app-api/serverless.yml
   2. Conventions:
      1. Each file in the handler directory should contain a single function called 'main'
      2. The handlers are organized by API, each with their own folder. Within those folders should be separate files per HTTP verb. For instance: There is a users folder in handlers, (services/app-api/handlers/users/). That folder would have individual files corresponding to an HTTP verb (e.g. get.js create.js update.js delete.js, etc.). The intention of this structure is that each request verb within a folder interacts with the table sharing the folder's name.
3. Add a wrapper function in /services/ui-src/src/libs/api.js example:

export function listUsers() {
  const opts = requestOptions();
  return API.get("amendments", `/users`, opts);
}

Adding New Forms (quarterly)

1. If necessary, create a new form template for the year in src/database/initial_data_load/

   1. Example: form_questions_2022.json

2. Add the new form to seed > form-questions > sources in services/data-deployment/serverless.yml

   Example:

    table: ${self:custom.stage}-form-questions
    sources:
    [
    ../../src/database/initial_data_load/form_questions_2022.json,
    ../../src/database/initial_data_load/form_questions_2021.json,
    ../../src/database/initial_data_load/form_questions_2020.json,
    ../../src/database/initial_data_load/form_questions_2019.json,
    ]
   

3. Log in to the site as an Administrator

4. Select Generate Quarterly Forms

5. Select the Year and Quarter for which you wish to generate forms

6. Click the Generate Forms button

SEDS & CARTS

SEDS feeds updates about its submissions to BigMac, and MDCT CARTS ingests those for calculations. See services/stream-functions for the implentation.

Legacy SEDS import SQL Files

SEDS has imported data from previous years, from the legacy SEDS project. The SQL Queries used can be found in src/dms.

Running the frontend unit test suite

1. Navigate to the frontend
   • cd services/ui-src
2. Launch the test for ui-src tests.
   • Run yarn test

Running the integration test suite

1. Launch cypress and select the file you want to run
   • Run yarn test:cypress

Running Schema Validation

Validate json files against schema to ensure accuracy before each commit.

• Schema Location: src/database/schema/
• Initial Data Location: src/database/initial_data_load

1. Install AJV globally in your environment
   1. npm install -g ajv-cli
2. Run validate command
   1. ajv -s /path/to/schema.json -d /path/to/json.json

Requirements

Node - we enforce using a specific version of node, specified in the file .nvmrc. This version matches the Lambda runtime. We recommend managing node versions using NVM.

Serverless - Get help installing it here: Serverless Getting Started page

Yarn - in order to install dependencies, you need to install yarn.

AWS Account: You'll need an AWS account with appropriate IAM permissions (admin recommended) to deploy this app in Amazon.

You'll also need to have java installed to run the database locally. M1 Mac users can download from azul. Note that you'll need the x86 architecture Java for this to work. You can verify the installation with java --version

If you are on a Mac, you should be able to install all the dependencies like so:

# install nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

# select the version specified in .nvmrc

nvm install
nvm use

# install yarn

brew install yarn

# run dev

./dev local

Dependencies

None.

Examples

None.
