 # report-server-ts
-Typescript and bun port of Report Server (Javascript node)
+  เป็น Web API ออกแบบมาเพื่อสร้างเอกสาร สามารถใช้ frontend โดยตรง เพื่อจะได้ไม่ต้องเขียนโปรแกรมทำเอกสารเฉพาะแต่ละตัวออกมา ปรับปรุงของเดิมจาก 
+เขียนใหม่เป็น TypeScript ตัด pandoc ออก เริ่มแรกลองใช้ bun แทน node รองรับ TypeScript โดยไม่ต้องตั้งค่า แต่มีปัญหากับ libreoffice-file-converter ต้องแก้ค่าใน package.json และ docker-template คาดว่าเป็นปัญหาจาก eval ทำให้  ส่วน EXEC กับ custom function ทำงานไม่ได้ เลยกลับมาใช้ node ตั้งค่าของ TypeScript [ตามเวปนี้](https://www.geeksforgeeks.org/how-to-use-express-in-typescript/) ให้ใช้ ES module ได้ด้วย
+
+```bash
+npm i express 
+npm i -D typescript @types/express @types/node ts-node
+npm i docx-templates xlsx-template-next swagger-ui-express swagger-jsdoc yaqrcode libreoffice-file-converter
+npm i -D @types/swagger-ui-express @types/swagger-jsdoc
+# obfuscate code tools
+npm i -D javascript-obfuscator
+# add type support for yaqrcode
+cd node_modules/yaqrcode
+wget https://raw.githubusercontent.com/zenozeng/node-yaqrcode/master/index.d.ts
+
+```
+# การใช้งาน
+ดู scripts ใน package.json และ compose.yaml
+```bash
+npm run dev
+npm run build
+npm run serve
+npm run obfuscator
+npm run preview
+npm run build:docker
+docker compose up -d
+```
+
+# ทดสอบ template
+ไปที่โฟลเดอร์ test-run จะมีโค้ดเพื่อทดสอบ template docx และ xlsx อย่างง่าย ใช้ค่า default ได้เลย สามารถทดสอบการแปลงไปไฟล์แบบต่างๆที่ Libreoffice รองรับได้ ควรทดสอบรูปแบบข้อมูล(json) ให้เข้ากับ template(docx,xlsx) ก่อนใช้งานเพราะ error log จะแสดงที่เซิร์เวอร์เท่านั้น
+``` bash
+$ npx ts-node docx-template.ts 
+Output extension(docx,pdf,odt): pdf
+JSON data path(./docx.json): 
+Base path of templates-docx(..): 
+
+$ npx ts-node xlsx-template.ts 
+Output extension(xlsx,pdf): ods
+JSON data path(./xlsx.json): 
+Base path of templates-docx(..):
+```
+
+
+
+# Build docker
+```bash
+docker build -t docker.frappet.com/demo/report-server .
+docker push docker.frappet.com/demo/report-server
+docker run --name rserver -p 80:3000 docker.frappet.com/demo/report-server
+```
+
+## report-templates/docx
+
+ใช้ library [docx-templates](https://www.npmjs.com/package/docx-templates) รับข้อมูลใน json กับ MS Word (template) เพิ่อสร้างเอกสาร MS Word สำหรับการใช้งาน PDF จะใช้ LibreOffice ในการแปลงจาก docx เป็น pdf เพื่อจะได้ตัดคำภาษาไทยได้
