Purpose and delivery model

BD Routings is a static, browser-only Bangladesh Bank Routing Number lookup tool. It supports reverse lookup from a 9-digit routing number and forward lookup from bank plus branch, with a separate printable bank-details card utility. There is no indicated backend, API, database, or server-side runtime.

User entry points

• index.html is the primary search interface. It exposes routing-number search and bank/branch-driven routing retrieval.

• card.html is a separate account/bank-details card generator intended for rendering and printing/sharing formatted details.

• googled3e9901256669fbd.html is a Google site-verification artifact, not an application flow.

Routing-data boundary

• banks.json is the application’s local authoritative dataset of Bangladesh Bank routing records.

• Browser-side JavaScript loaded by index.html is expected to load and query this dataset; the data file is the key boundary between lookup UI and banking-reference content.

• Because the dataset is static and locally hosted, accuracy updates are delivered by publishing a revised banks.json, rather than through a live financial-data integration.

Lookup flow

1. The main page loads its UI and routing dataset from index.html and banks.json.

2. For routing-number lookup, the entered 9-digit value is matched against routing records, returning bank, branch, and available address details.

3. For bank/branch lookup, the bank selection constrains the available branch selection; the selected pair resolves to one routing number.

4. Results are rendered in the page without a server round trip beyond static asset loading.

Card-generation flow

• card.html accepts account-holder and bank fields such as account name, account number, and routing number.

• It renders those inputs as a clean card suitable for printing or sharing.

• This utility is independent of the routing-search data path unless its page implementation explicitly reuses banks.json (not established by the supplied tree).

Runtime and infrastructure

• Runtime: standard web browser using HTML5, CSS, and client-side JavaScript.

• Hosting: GitHub Pages is the indicated deployment target (https://ridwanridu.github.io/bdroutings).

• Automation: the README’s deployment badge references a GitHub Actions deployment workflow, though workflow files are not present in the supplied tree.

• External dependency surface appears minimal: static hosting, optional Google ownership verification, and no documented external lookup service.
