IRS Form 990-PF Fetch :: Node.js Edition

Lightweight but powerful Node.js scripts to fetch all machine-readable IRS Form 990-PFs and insert into a MongoDB database.

Datasets: Public IRS data set hosted by Amazon AWS

What it Does

• Fetch each year's index of Form 990s
• Parse JSON and limit to Form 990-PFs
• Fetch XML tax filings
• Parse XML and convert to JavaScript objects
• Insert into MongoDB

The Scripts

1. indexes.js - Fetches index listings relating to IRS Form 990-PF filings for the specified tax year and inserts into MongoDB
2. filings.js - Fetches all IRS Form 990-PF filings for the specified tax year and inserts into MongoDB

Scripts Used by Grantmakers.io

1. fetch.js - Inserts individual index and filing info into MongoDB
2. aggregate.js - Combines info by EIN
3. normalize.js - Pulls specific information across tax year

Misc

1. utilities/ - Various scripts and Mongo queries.
2. experiments/ - In process experiments. These are often one-off items built on rainy Saturday mornings to scratch an itch, so tread carefully.

Usage

iMac with 16GB RAM
ulimit -n 4096 && mongod --dbpath ./data/db/
ulimit -n 4096 && node combined

MacBook Air with 8GB RAM (struggles)
ulimit -n 2048 && mongod --dbpath ./data/db/
ulimit -n 2048 && node combined

Note: The IRS no longer offers a single index for all filings. Thus, each script must be run once for each year (e.g. toggle the year).

Troubleshooting

See utilities/troubleshoot.js to log memory usage and toggle between using the npm request-promise package and the AWS JavaScript SDK.

Experiments

Testing out Google Cloud functions (see gcf_http folder) - first up is a simple script to check for updates.
