unofficial_jisho_api 2.0.4

An unofficial api for searching and scraping the japanese dictionary Jisho.org

unofficial_jisho_api

A rewrite of the unofficial-jisho-api

Usage

Below are some basic examples.

Word/phrase search (provided by official Jisho API)

This returns the same results as the official Jisho.org API. See the discussion of that here.

import 'package:unofficial_jisho_api/api.dart' as jisho;

void main() async {
  jisho.searchForPhrase('日').then((result) {
    ...
    ...
    ...
  });
}

Kanji search

import 'dart:convert' show jsonEncode;
import 'package:unofficial_jisho_api/api.dart' as jisho;

void main() async {
  await jisho.searchForKanji('語').then((result) {
    print('Found: ${result.found}');

    final data = result.data;
    if (data != null) {
      print('Taught in: ${data.taughtIn}');
      print('JLPT level: ${data.jlptLevel}');
      print('Newspaper frequency rank: ${data.newspaperFrequencyRank}');
      print('Stroke count: ${data.strokeCount}');
      print('Meaning: ${data.meaning}');
      print('Kunyomi: ${jsonEncode(data.kunyomi)}');
      print('Kunyomi example: ${jsonEncode(data.kunyomiExamples[0])}');
      print('Onyomi: ${jsonEncode(data.onyomi)}');
      print('Onyomi example: ${jsonEncode(data.onyomiExamples[0])}');
      print('Radical: ${jsonEncode(data.radical)}');
      print('Parts: ${jsonEncode(data.parts)}');
      print('Stroke order diagram: ${data.strokeOrderDiagramUri}');
      print('Stroke order SVG: ${data.strokeOrderSvgUri}');
      print('Stroke order GIF: ${data.strokeOrderGifUri}');
      print('Jisho Uri: ${data.uri}');
    }
  });
}

This outputs the following:

Found: true
Taught in: grade 2
JLPT level: N5
Newspaper frequency rank: 301
Stroke count: 14
Meaning: word, speech, language
Kunyomi: ["かた.る","かた.らう"]
Kunyomi example: {"example":"語る","reading":"かたる","meaning":"to talk about, to speak of, to tell, to narrate, to recite, to chant, to indicate, to show"}
Onyomi: ["ゴ"]
Onyomi example: {"example":"語","reading":"ゴ","meaning":"language, word"}
Radical: {"symbol":"言","forms":["訁"],"meaning":"speech"}
Parts: ["五","口","言"]
Stroke order diagram: https://classic.jisho.org/static/images/stroke_diagrams/35486_frames.png
Stroke order SVG: https://d1w6u4xc3l95km.cloudfront.net/kanji-2015-03/08a9e.svg
Stroke order GIF: https://raw.githubusercontent.com/mistval/kanji_images/master/gifs/8a9e.gif
Jisho Uri: https://jisho.org/search/%E8%AA%9E%23kanji

Example search

import 'dart:convert' show jsonEncode;
import 'package:unofficial_jisho_api/api.dart' as jisho;

void main() async {
  await jisho.searchForExamples('日').then((result) {
    print('Jisho Uri: ${result.uri}');
    print('');

    for (var i = 0; i < 3; i++) {
      var example = result.results[i];
      print(example.kanji);
      print(example.kana);
      print(example.english);
      print(jsonEncode(example.pieces));
      print('');
    }
  });
}

This outputs the following:

Jisho Uri: https://jisho.org/search/%E6%97%A5%23sentences

日本人ならそんなことはけっしてしないでしょう。
にほんじんならそんなことはけっしてしないでしょう。
A Japanese person would never do such a thing.
[{"lifted":"にほんじん","unlifted":"日本人"},{"lifted":null,"unlifted":"なら"},{"lifted":null,"unlifted":"そんな"},{"lifted":null,"unlifted":"こと"},{"lifted":null,"unlifted":"は"},{"lifted":null,"unlifted":"けっして"},{"lifted":null,"unlifted":"しない"},{"lifted":null,"unlifted":"でしょう"}]

今日はとても暑い。
きょうはとてもあつい。
It is very hot today.

日本には美しい都市が多い。例えば京都、奈良だ。

Japan is full of beautiful cities. Kyoto and Nara, for instance.
[{"lifted":"にほん","unlifted":"日本"},{"lifted":null,"unlifted":"には"},{"lifted":"うつく","unlifted":"美しい"},{"lifted":"とし","unlifted":"都市"},{"lifted":null,"unlifted":"が"},{"lifted":"おお","unlifted":"多い"},{"lifted":"たと","unlifted":"例えば"},{"lifted":"きょうと","unlifted":"京都"},{"lifted":null,"unlifted":"だ"}]

Word/phrase scraping

This scrapes the word/phrase page on Jisho.org. This can get you some data that the official API doesn't have, such as JLPT level and part-of-speech. The official API (searchForPhrase) should be preferred if it has the data you need.

import 'dart:convert';
import 'package:unofficial_jisho_api/api.dart' as jisho;
final JsonEncoder encoder = JsonEncoder.withIndent('  ');

void main() async {
  await jisho.scrapeForPhrase('谷').then((data) {
    print(encoder.convert(data));
  });
}

This outputs the following:

{
  "found": true,
  "query": "谷",
  "data": {
    "uri": "https://jisho.org/word/%E8%B0%B7",
    "tags": [

  }
}

Parsing HTML strings

You can provide the HTML responses from Jisho yourself. This can be useful if you need to use a CORS proxy or something. You can do whatever you need to do to get the HTML and then provide it to this module's parsing functions. For example:

Parse kanji page HTML

import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:unofficial_jisho_api/parser.dart' as jisho_parser;

final JsonEncoder encoder = JsonEncoder.withIndent('  ');

const String searchKanji = '車';
final String searchURI = jisho_parser.uriForKanjiSearch(searchKanji);

void main() async {
  await http.get(searchURI).then((result) {
    final parsedResult = jisho_parser.parseKanjiPageData(result.body, searchKanji);
    final data = parsedResult.data;
    if (data != null) {
      print('JLPT level: ${data.jlptLevel}');
      print('Stroke count: ${data.strokeCount}');
      print('Meaning: ${data.meaning}');
    }
  });
}

Parse example page HTML

import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:unofficial_jisho_api/parser.dart' as jisho_parser;

final JsonEncoder encoder = JsonEncoder.withIndent('  ');

const String searchExample = '保護者';
final String searchURI = jisho_parser.uriForExampleSearch(searchExample);

void main() async {
  await http.get(searchURI).then((result) {
    final parsedResult = jisho_parser.parseExamplePageData(result.body, searchExample);
    print('English: ${parsedResult.results[0].english}');
    print('Kanji ${parsedResult.results[0].kanji}');
    print('Kana: ${parsedResult.results[0].kana}');
  });
}

Parse phrase page HTML

import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:unofficial_jisho_api/parser.dart' as jisho_parser;

final JsonEncoder encoder = JsonEncoder.withIndent('  ');

const String searchExample = '保護者';
final String searchURI = jisho_parser.uriForPhraseScrape(searchExample);

void main() async {

  await http.get(searchURI).then((result) {
    final parsedResult = jisho_parser.parsePhrasePageData(result.body, searchExample);
    print(encoder.convert(parsedResult));
  });
}

Notes

The null-safety of dart 2.12 makes the parsing and interpreting of the native search API a little unreliable. Please be cautious when using jisho.searchForPhrase(), and if you do, please read the API docs about the different result values.
