• create_lambda Create a lambda. Returns its public address and a private editor key, the only way back in. It starts with version 1 - an empty starter, or a copy of a demo. No
• update_lambda Change how a lambda's editor opens: view 'Simple' shows the app, how it is doing and a box to ask for a change - for an owner who does not write code - and 'Ful
• write_code Save every file, replacing the previous set: as a new version of the lambda, or - with feature - into that feature. A version is its code and its resources. The
• change_code Change some files: add or replace files, remove files, or replace text within a file. Everything not named stays as it is, so there is no need to resend unchang
• create_feature Start a feature: a place to change a lambda without touching what it has online. It branches off a version - the newest unless base names another - with a copy
• update_feature Rename a feature, change what it says about itself, or move its base. merge_feature refuses a feature that is not based on the newest version, since merging it
• merge_feature Make a feature's files the next version of the lambda, and delete the feature with its preview and its copy of the data - the lambda's own data is not touched.
• delete_feature Throw a feature away: its files, its preview and its copy of the data. The lambda is not touched. For a feature the user does not want after all.
• check_code Compile without saving or deploying; returns diagnostics with file and line. Does not build the handler, so deploy can still refuse a route whose return type ca
• deploy Deploy (publish) a saved version so it goes live at its public address - the newest by default. With feature, deploy that feature's files to its own preview add
• read_lambda A lambda's status (online version, newest version, expiry, its tier and what it may use there), its open features, the recent versions with what each was asked
• read_logs What a deployed lambda has been doing: its recent requests and how they were answered, what it printed, the errors it threw with their stack traces, and how muc
• upload_file Write a file to the lambda's workspace - its data, which every version shares and no deploy, rollback or merge touches. With feature, to that feature's copy of
• list_files The lambda's data: whether its workspace is switched on, and every file in it with size and last write - the same whichever version is online. With feature, tha
• delete_file Remove a file, or a folder with its contents, from the workspace - the lambda's data, shared by every version. No deploy or rollback brings it back. With featur
• enable_data Switch on a kind of data the lambda needs and does not have: 'database' (a SQLite database for its records - off until switched on, which makes it, empty), 'sec
