news-please
news-please is an open source, easy-to-use news crawler that extracts structured information from almost any news website. It can recursively follow internal hyperlinks and read RSS feeds to fetch both most recent and also old, archived articles. You only need to provide the root URL of the news website to crawl it completely. news-please combines the power of multiple state-of-the-art libraries and tools, such as scrapy, Newspaper, and readability.
news-please also allows Python developers to use the crawling and extraction functionality within their own program. Moreover, news-please allows to conveniently crawl and extract articles from the (very) large news archive at commoncrawl.org.

news-please extracts the following attributes from news articles. An examplary json file as extracted by news-please can be found here.
- headline
- lead paragraph
- main text
- main image
- name(s) of author(s)
- publication date
- language
Features
- works out of the box: install with pip, add URLs of your pages, run :-)
- run news-please conveniently using its CLI mode
- use it as a library within your own software
- extract articles from commoncrawl.org’s news archive
Modes and use cases
news-please supports three main use cases, which are explained in more detail in the following.
CLI mode
- stores extracted results in JSON files, PostgreSQL, ElasticSearch, Redis, or your own storage
- simple but extensive configuration (if you want to tweak the results)
- revisions: crawl articles multiple times and track changes
Library mode
- crawl and extract information given a list of article URLs
- to use news-please within your own Python code
- commoncrawl.org provides an extensive, free-to-use archive of news articles from small and major publishers world wide
- news-please enables users to conveniently download and extract articles from commoncrawl.org
- you can optionally define filter criteria, such as news publisher(s) or the date period, within which articles need to be published
- clone the news-please repository, adapt the config section in newsplease/examples/commoncrawl.py, and execute
python3 -m newsplease.examples.commoncrawl
Getting started
It’s super easy, we promise!
Installation
news-please runs on Python 3.8+.
$ pip install news-please
Use within your own code (as a library)
You can access the core functionality of news-please, i.e. extraction of semi-structured information from one or more news articles, in your own code by using news-please in library mode. If you want to use news-please’s full website extraction (given only the root URL) or continuous crawling mode (using RSS), you’ll need to use the CLI mode, which is described later.
from newsplease import NewsPlease
article = NewsPlease.from_url('https://www.nytimes.com/2017/02/23/us/politics/cpac-stephen-bannon-reince-priebus.html?hp')
print(article.title)
A sample of an extracted article can be found here (as a JSON file).
If you want to crawl multiple articles at a time, optionally with any optional parameter taken by requests.request()
NewsPlease.from_urls([url1, url2, ...], request_args={"timeout": 6})
or if you have a file containing all URLs (each line containing a single URL)
NewsPlease.from_file(path)
or if you have raw HTML data (you can also provide the original URL to increase the accuracy of extracting the publishing date)
NewsPlease.from_html(html, url=None)
or if you have a WARC file (also check out our commoncrawl workflow, which provides convenient methods to filter commoncrawl’s archive for specific news outlets and dates)
NewsPlease.from_warc(warc_record)
In library mode, news-please will attempt to download and extract information from each URL. The previously described functions are blocking, i.e., will return once news-please has attempted all URLs. The resulting list contains all successfully extracted articles.
Finally, you can process the extracted information contained in the article object(s). For example, to export into a JSON format, you may use:
import json
with open("article.json", "w") as file:
json.dump(article.get_serializable_dict(), file)
Run the crawler (via the CLI)
$ news-please
news-please will then start crawling a few examples pages. To terminate the process press CTRL+C. news-please will then shut down within 5-60 seconds. You can also press CTRL+C twice, which will immediately kill the process (not recommended, though).
The results are stored by default in JSON files in the data folder. In the default configuration, news-please also stores the original HTML files.
Crawl other pages
Most likely, you will not want to crawl from the websites provided in our example configuration. Simply head over to the sitelist.hjson file and add the root URLs of the news outlets’ web pages of your choice. news-please also can extract the most recent events from the GDELT project, see here.
ElasticSearch
news-please also supports export to ElasticSearch. Using Elasticsearch will also enable the versioning feature. First, enable it in the config.cfg at the config directory, which is by default ~/news-please/config but can also be changed with the -c parameter to a custom location. In case the directory does not exist, a default directory will be created at the specified location.
[Scrapy]
ITEM_PIPELINES = {
'newsplease.pipeline.pipelines.ArticleMasterExtractor':100,
'newsplease.pipeline.pipelines.ElasticsearchStorage':350
}
That’s it! Except, if your Elasticsearch database is not located at http://localhost:9200, uses a different username/password or CA-certificate authentication. In these cases, you will also need to change the following.
[Elasticsearch]
host = localhost
port = 9200
...
# Credentials used for authentication (supports CA-certificates):
use_ca_certificates = False # True if authentification needs to be performed
ca_cert_path = '/path/to/cacert.pem'
client_cert_path = '/path/to/client_cert.pem'
client_key_path = '/path/to/client_key.pem'
username = 'root'
secret = 'password'
PostgreSQL
news-please allows for storing of articles to a PostgreSQL database, including the versioning feature. To export to PostgreSQL, open the corresponding config file (config_lib.cfg for library mode and config.cfg for CLI mode) and add the PostgresqlStorage module to the pipeline and adjust the database credentials:
[Scrapy]
ITEM_PIPELINES = {
'newsplease.pipeline.pipelines.ArticleMasterExtractor':100,
'newsplease.pipeline.pipelines.PostgresqlStorage':350
}
[Postgresql]
# Postgresql-Connection required for saving meta-informations
host = localhost
port = 5432
database = 'news-please'
# schema = 'news-please'
user = 'user'
password = 'password'
If you plan to use news-please and its export to PostgreSQL in a production environment, we recommend to uninstall the psycopg2-binary package and install psycopg2. We use the former since it does not require a C compiler in order to be installed. See here, for more information on differences between psycopg2 and psycopg2-binary and how to setup a production environment.
Redis
news-please allows to store articles on a Redis database, including the versioning feature. To export to Redis, open the corresponding config file (config_lib.cfg for library mode and config.cfg for CLI mode) and add the RedisStorage module to the pipeline and adjust the connection credentials:
[Scrapy]
ITEM_PIPELINES = {
'newsplease.pipeline.pipelines.ArticleMasterExtractor':100,
'newsplease.pipeline.pipelines.RedisStorage':350
}
[Redis]
host = localhost
port = 6379
db = 0
# You can add any redis connection parameter here
ssl_check_hostname = True
username = "news-please"
max_connections = 24
This pipeline should also be compatible with AWS Elasticache and GCP MemoryStore
What’s next?
We have collected a bunch of useful information for both users and developers. As a user, you will most likely only deal with two files: sitelist.hjson (to define sites to be crawled) and config.cfg (probably only rarely, in case you want to tweak the configuration).
Support
