From 292eebd9b3067cc2625c67f06d255a0cdbac92eb Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 9 Nov 2025 09:09:13 +0000 Subject: [PATCH] Add EUR currency support with multi-language translations - Created EUR calculation module (calculate-eur.js) for EUR-based satoshi calculations - Created btcpoll-eur.js to fetch and store EUR historical data from CoinGecko API - Added EUR historical data file structure (public/eur_historical) - Created locale files for 8 European languages (English, German, French, Spanish, Italian, Dutch, Portuguese, Polish) - Updated index.js with EUR routes for all language variants (/en-eur, /de, /fr, /es, /it, /nl, /pt, /pl) - Made template (sats.hbs) dynamic to support both HKD and EUR currencies with configurable exchange rates - Updated template to support up to 7 language links for EUR version - Added updaterate-eur.js for GitHub Actions to update EUR data daily - Updated GitHub Actions workflow to run both HKD and EUR data updates - Updated all locale files (HKD and EUR) with data_file, rate_field, and exchange_rate parameters This implementation allows the site to work with EUR currency and supports translations to all major European languages, preparing for deployment at eursat.eu domain. --- .github/workflows/main.yml | 3 +- btcpoll-eur.js | 80 ++++++++++++++++++++++++++++++++++++++ calculate-eur.js | 58 +++++++++++++++++++++++++++ index.js | 74 +++++++++++++++++++++++++++++++++++ locales/de.json | 35 +++++++++++++++++ locales/en-eur.json | 35 +++++++++++++++++ locales/en.json | 3 ++ locales/es.json | 35 +++++++++++++++++ locales/fr.json | 35 +++++++++++++++++ locales/it.json | 35 +++++++++++++++++ locales/nl.json | 35 +++++++++++++++++ locales/pl.json | 35 +++++++++++++++++ locales/pt.json | 35 +++++++++++++++++ locales/zh-cn.json | 3 ++ locales/zh-hk.json | 3 ++ public/eur_historical | 1 + updaterate-eur.js | 13 +++++++ views/sats.hbs | 9 ++--- 18 files changed, 521 insertions(+), 6 deletions(-) create mode 100644 btcpoll-eur.js create mode 100644 calculate-eur.js create mode 100644 locales/de.json create mode 100644 locales/en-eur.json create mode 100644 locales/es.json create mode 100644 locales/fr.json create mode 100644 locales/it.json create mode 100644 locales/nl.json create mode 100644 locales/pl.json create mode 100644 locales/pt.json create mode 100644 public/eur_historical create mode 100644 updaterate-eur.js diff --git a/.github/workflows/main.yml b/.github/workflows/main.yml index 630872b..f8bacd2 100644 --- a/.github/workflows/main.yml +++ b/.github/workflows/main.yml @@ -21,9 +21,10 @@ jobs: - name: add and push run: | - npm install + npm install npm install axios@0.26.1 --save node updaterate.js + node updaterate-eur.js date > generated.txt git config user.name github-actions git config user.email github-actions@github.com diff --git a/btcpoll-eur.js b/btcpoll-eur.js new file mode 100644 index 0000000..f7a29cd --- /dev/null +++ b/btcpoll-eur.js @@ -0,0 +1,80 @@ +const fs = require('fs') +const axios = require('axios');
