š„ New in v0.12+
š„ : Core functions support JSON Path.
Now all core functions return the correct and accurate JSON path for each linting result. Previously this was not possible at all, but with some clever engineering, we have made it happen. It's a small thing, but with huge impact.
This feature has been available on the OpenAPI functions for some time, however core functions were without a comparison. But no more! core functions have joined the party.
A new --no-clip
flag is available on the lint
command. This prevents message/path truncation.
v0.11+
: Ignore Linting Errors/Violations.
v0.11 introduces the ability to ignore specific linting errors. This is useful for when you want to implement new rules to existing production APIs. In some cases, correcting the lint errors would result in a breaking change.
Having a way to ignore these errors allows you to implement the new rules for new APIs while maintaining backwards compatibility for existing ones.
Learn more about ignoring violations
v0.10+
: Quality release.
v0.10 is a quality release, with a number of fixes and improvements to rule schemas, function names and more. vacuum now powers The OpenAPI doctor. To enable correct ruleset management and automation a number of functions have been renamed, interfaces have been upgraded and rule functions schemas are now accurate.
This is a breaking change for anyone using vacuum as a library with custom rules.
v0.9+
: Built in Language Server.
A new command is available language-server
. This starts vacuum as an LSP compatible language server. Run vacuum
in your favorite IDE and get linting and validation as you type, in realtime.
Will support any LSP compatible editor, like VSCode, Sublime, vim, etc.
Install the VSCode extension Learn more about the language-server command
v0.8+
: OpenAPI Bundler.
A new command is available bundle
will bundle all external references for an OpenAPI file into a single file.
Learn more about the bundle command
A new linting rule is available oas-schema-check
will perform type checks and validation on all schemas in your
OpenAPI file. It's enabled by default in the recommended ruleset.
v0.7+
: Hard Mode.
Want to lint your spec with the most strict ruleset possible? Now you can! Use the -z
/ --hard-mode
flag to enable
v0.6+
: Sharable / distributed rulesets now available.
Want to share / extend / distribute your own rulesets? Now you can!
Learn more about sharable rulesets
v0.5+
: Multi-file linting now available for the lint
command.
Want to lint multiple files at once? Now you can!
vacuum lint file1.json path/to/file2.yaml file3.json
Want to suck in a ton of files? Use a glob pattern!
vacuum lint some/path/**/*.yaml
v0.3+
: Custom JavaScript Functions are now available out of the box.
Write custom functions in JavaScript and use them in any ruleset. No need to compile golang code to extend vacuum anymore!
Learn more about building custom JavaScript functions.
v0.2+
: OWASP API rules are now available out of the box.
Learn more about enabling OWASP API rules.

vacuum can suck all the lint of a 5mb OpenAPI spec in milliseconds.
Designed to reliably lint OpenAPI specifications, very, very quickly. Including very large ones. Spectral can be quite slow when used as an API and does not scale for enterprise applications.
vacuum will tell you what is wrong with your spec, why, where and how to fix it.
vacuum will work at scale and is designed as a CLI (with a web or console UI) and a library to be consumed in other applications.
Dashboard
vacuum comes with an interactive dashboard (vacuum dashboard <your-openapi-spec.yaml>
) allowing you to explore
rules and violations in a console, without having to scroll through thousands of results.
HTML Report
vacuum can generate an easy to navigate and understand HTML report. Like the dashboard you can explore broken rules and violations, but in your browser.
No external dependencies, the HTML report will run completely offline.
Supports OpenAPI Version 2 (Swagger) and Version 3+
You can use either YAML or JSON, vacuum supports both formats.
Using vacuum with pre-commit
Vacuum can be used with pre-commit.
To do that, add to your .pre-commit-config.yaml
:
repos:
- repo: https://github.com/daveshanley/vacuum
rev: # a tag or a commit hash from this repo, see https://github.com/daveshanley/vacuum/releases
hooks:
- id: vacuum
See the hook definition here for details on what options the hook uses and what files it checks by default.
If no filenames or more than one filename in your repository matches the default files
pattern in the hook definition,
the pattern needs to be overridden in your config so that it matches exactly one filename to lint at a time.
To lint multiple files, specify the hook multiple times with the appropriate overrides.
Build an interactive HTML report
./vacuum html-report <your-openapi-spec.yaml | vacuum-report.json.gz> <report-name.html>
You can replace report-name.html
with your own choice of filename. Open the report
in your favorite browser and explore the results.
See full linting report
./vacuum lint -d <your-openapi-spec.yaml>
Lint multiple files at once
./vacuum lint -d <spec1.yaml> <spec2.yaml> <spec3.yaml>
Lint multiple files using a glob pattern
./vacuum lint -d some/path/**/*.yaml
See full linting report with inline code snippets
./vacuum lint -d -s <your-openapi-spec.yaml>
See just the linting errors
./vacuum lint -d -e <your-openapi-spec.yaml>
See just a specific category of report
./vacuum lint -d -c schemas <your-openapi-spec.yaml>
The options here are:
examples
operations
information
descriptions
schemas
security
tags
validation
owasp
Generate a Spectral compatible report
If you're already using Spectral JSON reports, and you want to use vacuum instead, use the spectral-report
command
./vacuum spectral-report <your-openapi-spec.yaml> <report-output-name.json>
The report file name is optional. The default report output name is vacuum-spectral-report.json
Generate a vacuum report
Vacuum reports are complete snapshots in time of a linting report for a specification. These reports can be 'replayed'
back through vacuum. Use the dashboard
or the html-report
commands to 'replay' the report and explore the results
as they were when the report was generated.
./vacuum report -c <your-openapi-spec.yaml> <report-prefix>
The default name of the report will be vacuum-report-MM-DD-YY-HH_MM_SS.json
. You can change the prefix by supplying
it as the second argument to the report
command.
Ideally, you should compress the report using -c
. This shrinks down the size significantly. vacuum automatically
recognizes a compressed report file and will deal with it automatically when reading.
When using compression, the file name will be
vacuum-report-MM-DD-YY-HH_MM_SS.json.gz
. vacuum uses gzip internally.
Ignoring specific linting errors
You can ignore specific linting errors by providing an --ignore-file
argument to the lint
and report
commands.
./vacuum lint --ignore-file <path-to-ignore-file.yaml> -d <your-openapi-spec.yaml>
./vacuum report --ignore-file <path-to-ignore-file.yaml> -c <your-openapi-spec.yaml> <report-prefix>
The ignore-file should point to a .yaml file that contains a list of errors to be ignored by vacuum. The structure of the yaml file is as follows:
<rule-id-1>:
- <json_path_to_error_or_warning_1>
- <json_path_to_error_or_warning_2>
<rule-id-2>:
- <json_path_to_error_or_warning_1>
- <json_path_to_error_or_warning_2>
...
Ignoring errors is useful for when you want to implement new rules to existing production APIs. In some cases, correcting the lint errors would result in a breaking change. Having a way to ignore these errors allows you to implement the new rules for new APIs while maintaining backwards compatibility for existing ones.
Try out the dashboard
This is an early, but working console UI for vacuum. The code isn't great, it needs a lot of clean up, but if you're interested in seeing how things are progressing, it's available.
./vacuum dashboard <your-openapi-spec.yaml | vacuum-report.json.gz>
Supply your own Spectral compatible ruleset
If you're already using Spectral and you have your own custom ruleset, then you can use it with vacuum!
The lint
, dashboard
and spectral-report
commands all accept a -r
or --ruleset
flag, defining the path to your ruleset file.
Here are some examples you can try
All rules turned off
./vacuum lint -r rulesets/examples/norules-ruleset.yaml <your-openapi-spec.yaml>
Only recommended rules
./vacuum lint -r rulesets/examples/recommended-ruleset.yaml <your-openapi-spec.yaml>
Enable specific rules only
./vacuum lint -r rulesets/examples/specific-ruleset.yaml <your-openapi-spec.yaml>
Custom rules
./vacuum lint -r rulesets/examples/custom-ruleset.yaml <your-openapi-spec.yaml>
_All rules, all of them!
./vacuum lint -r rulesets/examples/all-ruleset.yaml <your-openapi-spec.yaml>
Configuration
File
You can configure vacuum using a configuration file named vacuum.conf.yaml
By default, vacuum searches for this file in the following directories
- Working directory
$XDG_CONFIG_HOME
${HOME}/.config
You can also specify a path to a file using the --config
flag
Global flags are configured as top level nodes
time: true
base: 'http://example.com'
...
Command specific flags are configured under a node with the commands name
...
lint:
silent: true
...
Environmental variables
You can configure global vacuum flags using environmental variables in the form of: VACUUM_<flag>
If a flag, has a -
in it, replace with _
