CORS

SWS provides optional Cross-Origin Resource Sharing (CORS) support.

A list of allowed origin hosts (URLs) should be specified and separated by commas. Or an asterisk (*) can be used to allow any host.

This feature is disabled by default and can be controlled by the string -c, --cors-allow-origins option or the equivalent SERVER_CORS_ALLOW_ORIGINS env.

Below is an example of how to enable CORS.

static-web-server \
    --port 8787 \
    --root ./my-public-dir \
    --cors-allow-origins "https://domain.com"

    # Or use an asterisk to allow any host
    # --cors-allow-origins "*"

Allowed headers

The server also supports a list of CORS allowed headers separated by commas.

This feature depends on --cors-allow-origins to be used along with this feature. It can be controlled by the string -j, --cors-allow-headers option or the equivalent SERVER_CORS_ALLOW_HEADERS env.

Tips

Below is an example of how to CORS.

static-web-server \
    --port 8787 \
    --root ./my-public-dir \
    --cors-allow-origins "https://domain.com"
    --cors-allow-headers "origin, content-type, x-requested-with"
