name: transform-describe-image-with-transloadit
description: One-off image description using the official @transloadit/node CLI. Use image describe --fields labels for object-style labels, or image describe --for wordpress for structured alt text, title, caption, and description JSON.
Inputs
- Absolute path to a local input image
- Optional
.jsonoutput path; default is the same path with.json
Prepare
Resolve credentials in this order:
- Shell environment variables
- The current working directory
.envonly ~/.transloadit/credentials
If your .env lives in a parent directory, export the variables into the shell first.
Run
Use the official Transloadit Node CLI directly.
Labels / object-style description:
npx -y @transloadit/node image describe \
--input ./input.jpg \
--fields labels \
--output ./labels.json
WordPress-ready fields:
npx -y @transloadit/node image describe \
--input ./input.jpg \
--for wordpress \
--output ./fields.json
Custom field selection:
npx -y @transloadit/node image describe \
--input ./input.jpg \
--fields altText,title,caption,description \
--output ./fields.json
If you omit --output, the CLI writes the JSON file next to the input image using the same base
name. After the command finishes, confirm the JSON file exists at the expected output path.
Output Shapes
--fields labels returns a JSON array of labels.
--for wordpress and authored --fields ... return a JSON object with requested string fields, for example:
{
"altText": "...",
"title": "...",
"caption": "...",
"description": "..."
}
Notes
- Prefer
--for wordpresswhen you want publishable CMS fields. - Prefer
--fields labelswhen you want recognizer-style tags instead of authored copy. --modelonly matters for authored fields, not forlabels.- Prefer
~/.transloadit/credentialsas the default fallback when you want a reusable user-level setup. - A current-directory
.envstill takes precedence, so avoid it when deterministic account selection matters. - If credentials only exist in a repo-root
.env, run the command from that directory or export the variables first.
