openKB
openKB is a Markdown Knowledge base application (FAQ) built with Nodejs and ExpressJS. The application uses an embedded database (nedb) by default but can also use a MongoDB server by changing the config (see below). The application is designed to be easy to use and install and based around search rather than nested categories. Simply search for what you want and select from the results.
Demo: http://openkb.markmoffat.com
Installation
- Clone Repository:
git clone https://github.com/mrvautin/openKB.git && cd openKB
- Install dependencies:
npm install
- Start application:
npm start
- Go to http://127.0.0.1:4444 in your browser
Running the application in Production using minified code can be done by:
- Create the minified/ugly files:
npm run uglify
- Ensure the minified/ugly files are being used:
NODE_ENV=production node app.js
Note:
openKB
supports Nodejs version 0.12 and above.

yourself? ezyFAQ is a hosted solution with all the benefits and features of openKB
and more but using a fully managed/hosted
platform.
Features
- Search: openKB is a search based Knowledge base (FAQ) backed by Lunr.js indexing to create the best possible results on searches.
- Backend: openKB uses the pure Javascript nedb embedded database by default or a MongoDB server.
- Design/Themes: openKB is meant to be simple flat design. Themes can be added by creating a theme folder within
public/themes/
. See the example theme for more information. - Responsive: openKB is built using Bootstrap allowing it to be responsive and work on all devices. The
admin
can be a little difficult editing Markdown on smaller screens. - Mermaid: openKB allows for Mermaid charts in articles.
- Editor: openKB uses Markdown-it which is based off the CommonMark spec. This allows for the very best Markdown experience.
- Image management: openKB allows for drag and drop of images into articles. The image is automatically uploaded to the server in the background. Google Chrome users can also paste images directly from the clipboard.

Data sorting
You can control the sort order or articles. You can sort on anything but popular fields are kb_viewcount
, kb_published_date
, kb_last_updated
or kb_votes
Setting the sort_by
field in the config.json
like so:
{field: 'kb_viewcount', order: -1};
Valid order
values are: -1
or 1
1
= ascending order
-1
= decending order
Database setup
By default, openKB
uses an embedded Javascript database called nedb for easy installation. This works really well for small to medium sized applications but
has it's limitations if you wanted to scale your application to handle many articles and concurrent users. For this reason, openKB
also supports using a MongoDB server by simply changing the config file.
Here is the config.json
for the embedded database (NeDB):
"database": {
"type": "embedded"
}
Here is an example config.json
for a MongoDB server. You can use your own localhost MongoDB instance or you may choose a hosted MongoDB server like mLab.
"database": {
"type": "mongodb",
"connection_string": "mongodb://127.0.0.1:27017/openkb"
}
Alternately, for security reasons, you can use the Node environment variable (below) to store your MongoDB connection string.
MONGODB_CONNECTION_STRING
Public API
An optional public API can be enabled through /settings
to allow inserting of documents by HTTP POST using services like IFTTT etc.
Note:The API is disabled by default
Once turned on, the API is hosted on route: example.com/api/newArticle
via POST of a Object. The JSON schema is:
'type': 'object',
'properties': {
'api_auth_token': {'type': 'string'},
'kb_title': {'type': 'string'},
'kb_body': {'type': 'string'},
'kb_permalink': {'type': 'string'},
'kb_published': {'type': 'boolean'},
'kb_keywords': {'type': 'string'},
'kb_author_email': {'type': 'string'},
'kb_password': {'type': 'string'},
'kb_featured': {'type': 'boolean'},
'kb_seo_title': {'type': 'string'},
'kb_seo_description': {'type': 'string'}
},
'required': ['api_auth_token', 'kb_title', 'kb_body', 'kb_author_email', 'kb_published']
Note: An API access token is required to be able to use the API. If the API is turned on without a token, all requests will reject. Please use a hard to guess token
The return Object from the API will be as follows:
{
"result": false,
"errors": [
"Any error messages"
]
}
The errors
value will have any validation or error message which have occured. The result
is an approval boolean. Eg: true
was successful and false
wasn't.
Migrating from NeDB to MongoDB (experimental)
You can upgrade from NeDB to Mongodb by running the following command:
Note: You will first need to setup a valid MongoDB connection as per the "Database setup" instructions.
npm run-script dbUpgrade
please raise a Github issue if errors are encountered
Typeahead search
The typeahead search is great! Your user types in the word or phrase and the results pop up under the search box. But... One of the things to consider is that there is a little more data being transmitted from server to browser to enable this functionality. This is not normally a big issue for most browsers as the data is cached but you may run into issues if the number of articles in your app is quite large.
As a general rule there is about 3KB of compressed data being transferred from server to browser for 20 articles with long titles and keywords. If you have hundreds of articles, the amount of data will increase and could cause performance issues. It is something to consider if your app seems to slow down once the article numbers increase. If this is the case, you can simply just turn it off.
