Version history of Node.js server for offline export of Plotly.js graphs

(Note: This changelog focuses on the major changes between the different versions. Therefore, it may not contain all changes. Especially smaller fixes or improvements may be omitted.)

As a general rule the version tries to follow the Semantic Versioning scheme. Since Plotly.js is the main dependency of this application, major version changes in Plotly.js will also trigger a major version change in this application.

[maintenance] The version of Plotly.js is bumped from 2.22.0 to 2.23.1. The new version contains some fixes and changes. For details on those see the changelog of Plotly.js.

Version 4.0.0 (2023-05-11)

[breaking change] Generated image files are now served directly in the response to the request instead of just providing a JSON response that contains the file name of the generated image. That is, instead of returning a JSON response like
```
{
  "success": true,
  "filename": "graph-007e94ad-97c7-4f7b-9bf1-a524f689b8b5.svg"
}
```
the image is returned directly in the HTTP response message body.

This approach has several advantages:
- Users only need to make one request to the server instead of two to get the generated image.
- The server does not get filled with generated images files as in previous versions, because the images do not need to be stored for later retrieval anymore.

Version 2.6.1 (2023-05-01)

[maintenance] Update dependency jsdom to 21.1.2.

Version 2.6.0 (2023-04-23)

Version 2.1.2 (2022-11-24)

[maintenance] Update dependency jsdom to 20.0.3.

[maintenance] Update dependency ws to 8.11.0.

Version 2.1.0 (2022-10-30)

[feature] The dimensions of the generated image can now be adjusted by adding the HTTP headers X-Image-Width and / or X-Image-Height to the request. If none of them are specified, the size remains at 700 x 400 pixels as in version 2.0.2.

Version 2.0.0 (2022-10-29)

[breaking change] The file format of the generated images is changed from PNG to SVG. This is due to the internal replacement of PhantomJS with jsdom for rendering. PhantomJS does not work with newer versions of plotly.js (2.0 and later), so it had to be replaced. If you still need PNG files, then stick with version 1.5.7 of the application. However, version 1.5.7 is no longer maintained.

[breaking change] Support for Node.js 13 and older versions is dropped. The minimum required versions is now Node.js 14. Node.js versions before 14 have reached their end of life anyway, so users of those versions should upgrade to newer versions anyway.
[breaking change] The default image width is 700 pixels, and the default height is 400 pixels.

[maintenance] Update dependency minimist to 1.27.0.

Version 1.5.2 (2021-12-07)

[maintenance] Update dependencies asn1 to 0.2.6, json-schema to 0.4.0, jsprim to 1.4.2, mime-db to 1.51.0, and mime-types to 2.1.34.

Version 1.5.1 (2021-10-10)

[maintenance] Update dependencies core-util-is to 1.0.3, graceful-fs to 4.2.8, mime-db to 1.50.0, mime-types to 2.1.33.

Version 1.5.0 (2021-08-01)

[new feature] The port to which the server binds can now be changed by setting the environment variable PORT. If PORT is not set or is not a valid port number, then the default port 3000 is used.
[new feature] The hostname which the server shall use can now be changed by setting the environment variable HOST. If HOST is not set, then localhost will be used as default.

Version 1.4.2 (2021-08-01)

[maintenance] Update dependencies buffer-from to 1.1.2, mime-db to 1.49.0 and mime-types to 2.1.32.

Version 1.4.1 (2021-07-18)

[maintenance] The version of Plotly.js is bumped from 1.58.4 to 1.58.5.
[maintenance] The package dependencies mime-db and mime-types are updated to 1.48.0 and 2.1.31, respectively.

Version 1.4.0 (2021-04-18)

[improvement] The generated names for PNG files are using UUIDs (version 4) instead of a Unix timestamp in their name from now on. That is, the JSON output of a successful render will change from something like

{
  "success": true,
  "filename": "graph-1604764778687.png"
}

to something like

{
  "success": true,
  "filename": "graph-25273999-dea9-4da2-aad2-dbdf2e38a0c9.png"
}

instead. While it is highly unlikely that rendering of a plot with Plotly.js and JavaScript is so fast that two PNG files are created within the same millisecond this change makes sure we are on the safe side here.

Also note that the application never gave any guarantees for the naming pattern of the generated files in the first place. Therefore, anyone consuming the JSON response should treat the filename value as a purely random file name.

Version 1.3.0

The version of Plotly.js is bumped from 1.57.1 to 1.58.4.

Version 1.2.3

This is the initial release based on the ECharts server (https://gitlab.com/striezel/echarts-node-export-server) that does the same thing, just with ECharts.
