# Compare non-image files

Argos can compare more than screenshots. With the CLI, you can upload text-based artifacts such as API snapshots, generated HTML, Markdown files, CSS output, JavaScript bundles, XML documents, YAML files, or JSON fixtures and review their changes in Argos.

### Upload non-image files

Use the `-f` or `--files` option to tell the CLI which files to upload:

{% tabs %}
{% tab title="npm" %}

```
npm exec -- argos upload -f "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="yarn" %}

```
yarn run argos upload -f "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="pnpm" %}

```
pnpm exec -- argos upload -f "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="bun" %}

```
bun x argos upload -f "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}
{% endtabs %}

The `-f` option replaces the default screenshot glob. If you want to upload screenshots and non-image files in the same build, include both patterns:

{% tabs %}
{% tab title="npm" %}

```
npm exec -- argos upload -f "**/*.{png,jpg,jpeg}" "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="yarn" %}

```
yarn run argos upload -f "**/*.{png,jpg,jpeg}" "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="pnpm" %}

```
pnpm exec -- argos upload -f "**/*.{png,jpg,jpeg}" "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}

{% tab title="bun" %}

```
bun x argos upload -f "**/*.{png,jpg,jpeg}" "**/*.{txt,json,yaml,yml,xml,html,md,css,js}" ./snapshots
```

{% endtab %}
{% endtabs %}

Use stable file names and paths so Argos can match each uploaded file with its baseline on future builds.

### Supported content types

Argos currently supports these non-image content types:

* `text/plain`

### Framework support

Non-image comparisons are only supported through the CLI for now. [Contact us](https://argos-ci.com/contact) if you are interested in using this feature from a test framework like Vitest.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://argos-ci.com/docs/learn/how-to-guides/visual-coverage/compare-non-image-files.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
