dbf-reader

dbf-reader

A Node.js/Typescript module to read tabular data from the dBase DB (.dbf) file.

Installation

npm install dbf-reader --save
yarn add dbf-reader
bower install dbf-reader --save

Usage

TypeScript

Case 1: Reading (.dbf) file from local path 'D:\Workspace\tests\sampleFiles\sample.dbf'

import { Dbf } from 'dbf-reader';
import { DataTable } from 'dbf-reader/models/dbf-file';
import * as fs from "fs";

let buffer:Buffer=fs.readFileSync('/Workspace/tests/sampleFiles/sample.dbf')
let datatable:DataTable = Dbf.read(buffer);
if (datatable) {
    datatable.rows.forEach((row: any) => {
        datatable.columns.forEach((col: Column) => {
            console.log(row[col.name]);
        });
    });
}

Output should be an instance of DataTable class

Case 2: Reading (.dbf) file from 'File' input HtmlElement

<input type="file" id="avatar" (change)="onFileChange($event)" #fileInput>

import { Dbf } from 'dbf-reader';
import { DataTable } from 'dbf-reader/models/dbf-file';
import * as fs from "fs";
 
onFileChange(event) {
    let reader = new FileReader();
    if (event.target.files && event.target.files.length > 0) {
      let file = event.target.files[0];
      reader.readAsArrayBuffer(file);
      reader.onload = () => {
        var arrayBuffer: ArrayBuffer = reader.result as ArrayBuffer;
        if (arrayBuffer) {
          let buffer: any = Buffer.from(arrayBuffer);
          let datatable:DataTable = Dbf.read(buffer);
        }
      };
    }
  }
