Compress a string within Aura to limit the size of URL parameters

Question

Question: Is it possible to compress and decompress(or encoding/decoding) a string(or a large JSON) within an Aura component that has to be passed via URL parameters using Salesforce standard libraries (EncodingUtil class) ?

Scenario: I have an Lightning Aura comp on an object detail page that contains few weblinks. Clicking on any of these links would open a subtab (using WorkspaceAPI) where I am setting Pagereference.State value with some values from the parent component. As our application is growing with more data elements, so does the Pagereference.State. To reduce the overall State parameters, I am trying to explore ways to decrease the length of the parameters to hold same data, but transfer in compressed approach.

Findings: In my research, we would need some JS libraries to do the heavy lifting on the decoding/encoding aspect. But, these could pose some security concerns as we would be relying on some external sources.

Any recommendations are welcome.

Answer 1

EncodingUtil doesn't have any kind of compression features. Compression in Apex is usually accomplished via third-party code, such as Zippex. Client-side compression can be achieved with something like lz-string. Note that in Salesforce, code hosted off-platform is forbidden in Aura and LWC; you would instead save the code as a Static Resource or as a component library in Aura or LWC. At no point can you rely on external resources outside your control, so there is zero security risk.
