USE UNDER YOUR OWN RISK

Generate pdf tables with javascript (PDFKIT plugin)

Helps to draw informations in simple tables using pdfkit. #server-side.

Examples

view pdf example | color pdf | full code example | server example | json example | all

Install

npm install pdfkit-table-fx

Use

  // requires
  const fs = require("fs");
  const PDFDocument = require("pdfkit-table-fx");

  // init document
  let doc = new PDFDocument({ margin: 30, size: 'A4' });
  // save document
  doc.pipe(fs.createWriteStream("./document.pdf"));
  
  ;(async function createTable(){
    // table
    const table = { 
      title: '',
      headers: [],
      datas: [ /* complex data */ ],
      rows: [ /* or simple data */ ],
    };

    // the magic (async/await)
    await doc.table(table, { /* options */ });
    // -- or --
    // doc.table(table).then(() => { doc.end() }).catch((err) => { })

    // if your run express.js server
    // to show PDF on navigator
    // doc.pipe(res);

    // done!
    doc.end();
  })();

Examples

Server response

server example

  // router - Node + Express.js
  app.get('/create-pdf', async (req, res) => {
    // ...await table code
    // if your run express.js server
    // to show PDF on navigator
    doc.pipe(res);
    // done!
    doc.end();
  });

Example 1 - Simple Array

  ;(async function(){
    // table 
    const table = {
      title: "Title",
      subtitle: "Subtitle",
      headers: [ "Country", "Conversion rate", "Trend" ],
      rows: [
        [ "Switzerland", "12%", "+1.12%" ],
        [ "France", "67%", "-0.98%" ],
        [ "England", "33%", "+4.44%" ],
      ],
    };
    // A4 595.28 x 841.89 (portrait) (about width sizes)
    // width
    await doc.table(table, { 
      width: 300,
    });
    // or columnsSize
    await doc.table(table, { 
      columnsSize: [ 200, 100, 100 ],
    });
    // done!
    doc.end();
  })();

Example 2 - Table

  ;(async function(){
    // table
    const table = {
      title: "Title",
      subtitle: "Subtitle",
      headers: [
        { label: "Name", property: 'name', width: 60, renderer: null },
        { label: "Description", property: 'description', width: 150, renderer: null }, 
        { label: "Price 1", property: 'price1', width: 100, renderer: null }, 
        { label: "Price 2", property: 'price2', width: 100, renderer: null }, 
        { label: "Price 3", property: 'price3', width: 80, renderer: null }, 
        { label: "Price 4", property: 'price4', width: 43, 
          renderer: (value, indexColumn, indexRow, row, rectRow, rectCell) => { return `U$ ${Number(value).toFixed(2)}` } 
        },
      ],
      // complex data
      datas: [
        { 
          name: 'Name 1', 
          description: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean mattis ante in laoreet egestas. ', 
          price1: '$1', 
          price3: '$ 3', 
          price2: '$2', 
          price4: '4', 
        },
        { 
          options: { fontSize: 10, separation: true},
          name: 'bold:Name 2', 
          description: 'bold:Lorem ipsum dolor.', 
          price1: 'bold:$1', 
          price3: { 
            label: 'PRICE $3', options: { fontSize: 12 } 
          }, 
          price2: '$2', 
          price4: '4', 
        },
        // {...},
      ],
      // simeple data
      rows: [
        [
          "Apple",
          "Nullam ut facilisis mi. Nunc dignissim ex ac vulputate facilisis.",
          "$ 105,99",
          "$ 105,99",
          "$ 105,99",
          "105.99",
        ],
        // [...],
      ],
    };
    // the magic
    doc.table(table, {
      prepareHeader: () => doc.font("Helvetica-Bold").fontSize(8),
      prepareRow: (row, indexColumn, indexRow, rectRow, rectCell) => {
        doc.font("Helvetica").fontSize(8);
        indexColumn === 0 && doc.addBackground(rectRow, 'blue', 0.15);
      },
    });
    // done!
    doc.end();
  })();

Example 3 - Json

  ;(async function(){
    // renderer function inside json file
    const tableJson = '{ 
      "headers": [
        { "label":"Name", "property":"name", "width":100 },
        { "label":"Age", "property":"age", "width":100 },
        { "label":"Year", "property":"year", "width":100 }
      ],
      "datas": [
        { "name":"bold:Name 1", "age":"Age 1", "year":"Year 1" },
        { "name":"Name 2", "age":"Age 2", "year":"Year 2" },
        { "name":"Name 3", "age":"Age 3", "year":"Year 3",
          "renderer": "function(value, i, irow){ return value + `(${(1+irow)})`; }"
        }
      ],
      "rows": [
        [ "Name 4", "Age 4", "Year 4" ]
      ],
      "options": {
        "width": 300
      }
    }';
    // the magic
    doc.table(tableJson);
    // done!
    doc.end();
  })();

Example 4 - Json file (many tables)

  ;(async function(){
    // json file
    const json = require('./table.json');
    // if json file is array
    Array.isArray(json) ? 
    // any tables - array
    await doc.tables(json) : 
    // one table - string
    await doc.table(json) ;
    // done!
    doc.end();
  })();

  ],
  // complex content
  datas: [
    { name: 'bold:Jack', age: 32, },
    // age is object value with style options
    { name: 'Maria', age: { label: 30 , options: { fontSize: 12 }}, },
  ],
  // simple content (works fine!)
