The USAspending website is the public-facing site offering information on Government spending for the United States. It utilizes the Data Transparency User Interface Library.
- To contribute to frontend development, follow Install and Configure below.
- To simply run the USAspending website locally, jump to Build and Run with Docker below.
Assumptions:
- You're able to install software on your machine.
- You have git installed on your machine and are able to clone code repositories from GitHub. If this isn't the case, the easiest way to get started is to install GitHub Desktop, available for Windows or Mac.
- You're familiar with opening a terminal on your machine and using the command line as needed.
Get the code and install the runtime and dependencies
- From the command line, clone the USAspending website repository from GitHub to your local machine, and get into the root directory:
$ git clone https://github.com/fedspendingtransparency/usaspending-website $ cd usaspending-website
- Download Node Version Manager (
nvm
) and install Node.js20.12.2
$ nvm install 20.12.2
- Set Node Package Manager (
npm
) CLI to version10.8.3
.$ npm i -g [email protected]
- Perform an install to get an exact dependency tree:
$ npm ci --legacy-peer-deps
- Run the site in a local dev server:
$ npm start
Alter configuration to non-default values by changing environment variable values.
Our site makes use of certain environment variables. Defaults are provided, but can be overridden by export
of new values in your local shell. These are the important ones:
ENV VAR | DEFAULT VALUE (if not set) | PURPOSE |
---|---|---|
ENV |
prod | Determine bundling optimizations and feature flags |
USASPENDING_API |
https://api.usaspending.gov/api/ | API URL to get backend data |
MAPBOX_TOKEN |
'' | Product key for use of MapBox features |
GA_TRACKING_ID |
'' | Google Analytics key for anonymously tracking usage |
Custom and life-cycle scripts to execute, as defined under the scripts
property in package.json
Script | Output |
---|---|
npm start |
dev server with hot reloading |
npm prod |
generates static assets w/ production optimization |
npm dev |
generates static assets w/ development optimization |
npm lint |
executes linter |
npm test |
executes unit tests |
npm sass |
dev server w/ scss source maps |
npm travis |
executes travis validation script |
npm ci |
clean existing Node dependencies and install dependencies |
npm run build-storybook |
builds storybook files |
npm run storybook |
starts storybook server so you can interact with stories |
Docker can be used to build static site artifacts and/or run the site locally. Ensure your environment variables are configured and use this "one-liner" (or decompose and run each docker
command separately):
docker build -t usaspending-website . && \
docker run --rm -v $(pwd)/public:/node-workspace/public \
-e ENV \
-e USASPENDING_API \
-e MAPBOX_TOKEN \
-e GA_TRACKING_ID \
usaspending-website npm run ${ENV} && \
docker run --rm -v $(pwd)/public:/usr/share/nginx/html:ro -p 8020:80 nginx:1.18
The first two steps can take 5+ minutes each, so this could be a total of ~10 minutes before ready.
What this does:
- Ensure your
usaspending-website
Docker image has the latest dependencies: - Generate and bundle static artifacts and output to
./public
- Mount the static artifacts to a running container of an nginx image and host at port
8020
You should see console logs, and the app should now be running at http://localhost:8020
.
Common build issues
- Webpack cannot be found:
npm i -g webpack
- npm install finishes with vulnerabilities:
npx force-resolutions
thennpm install
If there are still vulnerabilities after this, they may be newly discovered and we may have to update versions of packages, discuss with the team before doing so
