CAVEATS:
Version 0.7.0 includes a quick scan for the presence of a SBOM, either a bom.xml
for CycloneDX or *.spdx
/*spdx.rdf
for SPDX.
Version 0.6.0 includes breaking changes to the analyze function -> upgrading from 0.5.0 to 0.6.0 will require you to pass in a couple extra arguments to the analyze function:
AnalyzerModule.analyze(["https://github.com/gtri/lowendinsight","https://github.com/gtri/lowendinsight-get"], "iex", DateTime.utc_now(), %{types: true})
In version 0.6.0 the DateTime.utc_now()
and new options
field %{types: true}
are required.
LowEndInsight is a simple "bus-factor" risk analysis library for Open Source Software which is managed within a Git repository. Provide the git URL and the library will respond with a basic Elixir Map structure report. (There is a desire to make this a struct.)
If you are at all concerned about risks associated with upstream dependency requirements LowEndInsight can provide valuable, and actionable information around the likelihood of critical issues being resolved, if ever reported. For example, a repo with a single contributor isn't necessarily bad, but it should be considered with some level of risk. Are you or your organization willing to assume ownership (fork) of the repository to resolve issues yourself? Or if there hasn't been a commit against the source repository, in some significant amount of time, can you assume that it is inactive, or just stable?
While, in terms of DevSecOps, we are moving towards automation of vulnerability scanning, this doesn't tell the whole picture. First problem is that not all vulnerabilities are found/known, nor are all reported. So perhaps some risk reduction should be applied at the dependency inclusion steps.
Again, the intent of LowEndInsight isn't to say that any upstream Open Source dependency is bad, just that the risks should be smartly weighed, and a deeper understanding of the implications should be gained during the decision to use. LowEndInsight provides a simple mechanism for investigating and applying basic governance (based on a definition of the tolerance level, which you can easily override) and responds with a useful report for integrating into your existing DevSecOps automation. Or, you can easily use LowEndInsight as an ad-hoc reporting tool, running it manually as part of an ADR.
-
Functional Contributors - we've found that most projects receive a majority of contributions from one or two contributors. This highlights a misconception about a project's number of contributors and some notion of health or maturity. We report both the total number of contributors, and our notion of "functional contributors" making it easy to identify the risk.
-
Commit Currency - we've found that many projects are active, while many are also dormant or stale. This isn't saying anthing of the quality of the project, but actually highlights potential supply-chain issues, e.g., is the project staying current with upstream dependencies updates
-
SBOM presence - we've found that adoption of a standard software-bill-of-materials (SBOM) manifest is lagging, especially in smaller projects. Again, the presence or lack thereof does not indicate quality or maturity, however, it does highlight the need to address provenence and risk management.
-
Recent Commit Change - we've found that project volatility could indicate project instability, but more likely highlights an active project - though it is very difficult to discern this based on amounts of change, and thus should require more due diligence applied when looking at the stability of a dependency.

LowEndInsight available in Hex, the package can be installed
by adding lowendinsight
to your list of dependencies in mix.exs
:
def deps do
[
{:lowendinsight, "~> 0.5"}
]
end
NOTE: check hex.pm for the latest version.
You either need to have Elixir and Erlang installed locally or possibly a container to run stuff in.
It is also possible to drop this in as a library dependency to your Mix-based Elixir project. Simply add the library to your project's dependencies:
defp deps do
[
{:lowendinsight, "~> 0.5", except: :prod, runtime: false}
]
end
Then run mix deps.get
, and mix lei.scan
. This will produce a report for the dependencies (and transitive dependencies) specified in your Mix definition.
You'll get a full report:
âžś lei_scanner_test mix lei.scan

"data": {

...
It is also possible to scan against a different repo locally by passing the absolute path to the directory where it is cloned:
mix lei.scan /some/path/to/a/git/repo
Lowendinsight can now be run against NPM-Based projects. To do so, simply clone the repository and run the following from lowendinsight's root directory.
mix deps.get
mix lei.scan /some/path/to/a/git/repo
It is important to note that though lowendinsight works on NPM-based projects, scanning still requires a local installation of Mix.
At the least, the above requires an existing package.json
file in order to scan the first-degree dependencies of an NPM-based project. A complete scan of both first-degree and transitive dependencies requires a package-lock.json
file. In other words, due to how NPM handles dependencies, a complete scan of a repository can only be accomplished if all of its dependencies are listed in package-lock.json
.
In the scope of package.json
, dependencies listed in both devDependencies
and dependencies
are scanned. Future iterations of lowendinsight could offer the ability to disable devDependencies
from being scanned.
mix lei.dependencies /some/path/to/a/Mix-based-project
The library uses a baseline configuration for each of the metrics calculated. If you want to set your own, all you need to do is add the :lowendinsight
configuration as mentioned below in the Configuration section. Tuning of these defaults will likely happen over time, as analysis continues to run on a large scale. The analysis will be made available here soon.

Here's the command that you would paste in to the iex
REPL as an example:
AnalyzerModule.analyze "https://github.com/kitplummer/xmpp4rails", "iex", %{types: false}
You can pass in this lib and configuration settings, into a base Elixir container. From the root directory of a clone of this repo run this:
docker run --rm -v $PWD:/app -w /app -it -e LEI_CRITICAL_CURRENCY_LEVEL=60 elixir:latest bash -c "mix local.hex;mix deps.get;iex -S mix"
From iex you can access to the library functions.

}
},

There is also an Elixir mix
task that you can use to access the
AnalyzeModule.analyze(url, client)
function. So if have this repo cloned:
mix lei.analyze
mix lei.analyze https://github.com/kitplummer/xmpp4rails | jq
This will return:
{
"state": "complete",
"report": {
"uuid": "86ac4538-4a28-11ea-897f-82dd17abe001",

"source_client": "mix task",
...
}
There also is a batch/bulk processor:
mix lei.bulk_analyze
mix lei.bulk_analyze "./test/scan_list_test" | jq
The expected file is a simple list of URLs, one per line like this:
https://github.com/gtri/lowendinsight
https://github.com/gtri/lowendinsight-get
Lowendinsight can also be added to a GitHub workflow as an action. In its current state, it works against both NPM and Mix based projects. When run against a GitHub repository, a .json
file will be generated of the format lei--Y-m-d--H-M-S.json
and pushed to that repository's root directory by default. This action currently exists in the develop branch. The following is an example usage:
name: LEI
on:
push:
branches: [ master ]
pull_request:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- uses: actions/checkout@master
with:
persist-credentials: false # otherwise, the token used is the GITHUB_TOKEN, instead of your personal token
fetch-depth: 0 # otherwise, you will fail to push refs to dest repo
- name: Generate Report
uses: gtri/lowendinsight@gha
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
branch: main
name | value | default | description |
---|---|---|---|
github_token | string | Token for the repo. Can be passed in using ${{ secrets.GITHUB_TOKEN }} . |
|
branch | string | 'master' | Destination branch to push changes. |
force | boolean | false | Determines if force push is used. |
tags | boolean | false | Determines if --tags is used. |
directory | string | '.' | Directory to change to before pushing. |
repository | string | '' | Repository name. Default or empty repository name represents current github repository. If you want to push to other repository, you should make a [personal access token] |
This action does not, nor will it ever, collect user data. Any repository used is Lowendinsight's analysis is cloned and deleted without any information being collected by GTRI nor sent to a third party.
Also, there is a sister project that wraps this library and provides an HTTP-based interface.

API available at: https://hexdocs.pm/lowendinsight/readme.html#content
This is the library piece of the puzzle. As mentioned above there is an HTTP API available as well.
The library is written in Elixir.
mix docs
will generate static docs available locally within the repo's root, in the docs/
subdirectory.
LowEndInsight makes available the API's schema in JSON form, which can be found in the schema/
subdirectory. In addition, the schema docs are available in schema/docs
as Markdown.
- Recent commit size: This is a measure of how large the most recent commit is in relatino to the size of the codebase. The idea being that a large recent commit is much more likely to be bug filled than a relatively small commit.
- Functional Contributors: A functional contributor is one that contributes above a certain percentage of commits equal to or greater than their "fair" share. Simply put, a contributor is counted as a functional contributor if the proportion of their commits to the total commits is greater than or equal to 1 / the total number of committers. If everyone committed the same amount, everyone would be a functional contributor.
- Currency is a bit of insight into the activity of the source repo. This value as a measure of risk, again, isn't to state that the repo is bad. The project simply could be stable. But, it could also mean that the project is unmaintained and that as an attribute of the decision making process around whether to not consume should be considered.
risk
is a top-level key that contains the "rolled up" risk, the highest value pulled from any of the discrete analysis items.
LowEndInsight allows for customization of the risk levels, to determine "low", "medium", "high" and "critical" acceptance. The library reads this configuration from config.exs (or dev|test|prod.exs) as seen here, or as providing in environment variables.
config :lowendinsight,

To override with an environment variable you just need to have it set:
LEI_CRITICAL_CURRENCY_PAR_LEVEL=60 mix lei.scan
If you receive an error in the report with the following (or similar missing environment configuration variable) - the required configuration for LowEndInsight hasn't been made available:
could not fetch application environment :critical_contributor_level for application :lowendinsight because the application was not loaded/started. If your application depends on :lowendinsight at runtime, make sure to load/start it or list it under :extra_applications in your mix.exs file
Thanks for considering, we need your contributions to help this project come to fruition.
Here are some important resources:
- Bugs? Issues is where to report them
The repo includes auto-formatting, please run mix format
to format to
the standard style prescribed by the Elixir project:
https://hexdocs.pm/mix/Mix.Tasks.Format.html https://github.com/christopheradams/elixir_style_guide
Code docs for functions are expected. Examples are a bonus:
https://hexdocs.pm/elixir/writing-documentation.html
Required. Please write ExUnit test for new code you create.
Use mix test --cover
to verify that you're maintaining coverage.
Just getting this built-out. But the bitbucket-pipeline config is still here too.
Please send a Pull Request with a clear list of what you've done and why. Please follow Elixir coding conventions (above in Style) and make sure all of your commits are atomic (one feature per commit).
Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
$ git commit -m "A brief summary of the commit
>
> A paragraph describing what changed and its impact."
The JSON schema found in schema
is and should be used to validate the main analysis interfaces' input and expected outputs. Any modifications in implementations should also be made to the schemas and verified/validated by tests.
There is an external tool used to do the schema docs conversion: jsonschema2md -d schema/ -o schema/docs
. If you make a modification to the schema please run the tool to update the docs with the submission.
jsonschema2md
is a Node.js tool.

For a bit of insight into the licensing part of inclusion within another licensed repo, there's this, which is really interesting.
The logic for pulling the code in versus the project as a dependency is that mix-deps-json
is really a server I the transitive dependencies aren't worth the weight.
