JIRA Miner Build Status Coverage Status

A tool to gather data from JIRA and query them locally for better speed and more flexible query language than jql. The tool stores entries available in JIRA locally in Loki.js database in a file. This means the tool has no dependency but Node.js


The tool is intended to act both as command line tool or a library in other projects. In order to be able to effectively query something, you need to populate the database first. Afterwards, you can query content of the database pretty easily.

You can install the tool by

npm install -g jira-miner

Or, use development copy by

git clone && cd jira-miner && npm link

Command line usage follows next, make sure you consult jira-miner help if you need further information. You can also run the tool setting DEBUG=1 environment variable, which will provide bunyan log traces useful for debugging.

Connecting to JIRA instance

You need to point jira-miner to a JIRA instance you want to use as data source. You might need to provide your credentials as well in order to access restricted data.

jira-miner target <jiraUri> [--user <user>] [--password [password]]

Populate & update local database

Once, you have targeted a jira, you can populate local database

jira populate <jqlQuery>

EXAMPLE: jira-miner populate "project in (AGPUSH, ARQ)" downloads all issues (including their history) for projects AGPUSH and ARQ)

If you rerun the query, it will rewrite all updated items. It might be a good idea to update the database since the last query to limit the amount of fetched data. You can do that via --since argument that accepts a timestamp.

TIP: For very large queries, you might run out of memory. You can increase memory of node process and reduce GC calls via following:

node --max_old_space_size=4096 --nouse-idle-notification index.js populate

Query the database

JIRA miner provides an API to query the database. Query must be defined in one of following formats:

const query = ctx => {
  // ctx.acc contains result of previous call
  // ctx.collection contains Loki.js collection
  // ctx.args contains optional arguments, such as ones on command line
// or
const query = [
  ctx => {
    return xyz    
  ctx => {
    // ctx.acc now contains a result of previous function call
// or
const query = [
  { 'age': {'$gt': 21 } /* Loki.js Mongo like query */ }
// or mix of function and Loki.js queries
module.exports = {query}

Supposing that this file, called my-example-query.js is in current directory, you call it via following

jira-miner query my-example-query [--args]

All arguments passed on command line will be available in ctx.args object. Example query files is available in tests/fixtures

Debug output

Simply run any command with --debug parameter



npm install -g tape tap-xunit istanbul coveralls

Afterwards, you can run tests via following command:

npm test

XUnit compatible report generated in report.xml file:

npm run xunit

Code coverage (via Istanbul tool):

npm run coverage


npm i jira-miner
