Tools

• analytics ~324 tokens
  How people reach a lambda, as its owner sees it in the editor: visitors, pages opened and requests per day, and the pages, referring sites, countries, devices, browsers, operating systems and crawlers (search engines, AIs, link previews) behind them. Counted by day in UTC and written down every few
• change_code ~819 tokens
  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 unchanged files. With feature, the change is saved into that feature - the way to work on a lambda that exists: change it as often as you like, dep
• check_code ~230 tokens
  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 cannot be served.
• create_feature ~356 tokens
  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 of its files (its documentation and tests included) and a copy of the lambda's data, and gets an address of its own to try it at. Change it
• create_lambda ~328 tokens
  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. Nothing is online until deploy.
• delete_feature Deletes data · ~112 tokens
  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.
• delete_file Changes files · Deletes data · ~156 tokens
  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 feature, from that feature's copy instead.
• delete_secret Deletes data · ~164 tokens
  Remove a secret. Code that reads it with Secret.Read fails from its next call on. Only when the user asks for it, or a secret you stored yourself is no longer used. With feature, from that feature's copy instead.
• deploy ~190 tokens
  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 address instead, against its copy of the data, leaving the lambda alone. Returns diagnostics on failure, and whatever was online stays online.
• enable_data ~249 tokens
  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), 'secrets' (off until switched on) or 'workspace' (on unless the owner switched it off). Do it when what you build needs it - records need the da
• list_demos ~133 tokens
  Demos this platform keeps online, each a finished lambda showing one way to build something: a REST API over records, registration and login, a websocket game, uploads, live updates. Their keys are public and read only: read the closest one with read_lambda (and list_files, read_logs) before writing
• list_files ~151 tokens
  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, that feature's copy of it. The code and resources of a version are in read_lambda.
• list_secrets ~176 tokens
  The lambda's secrets by name - never their values: whether secrets are switched on, what is stored and when, which names the code reads with Secret.Read and have no value yet (missing) - what the user still has to set - and which it only uses when they are there, checked with Secret.Exists (optional
• merge_feature ~317 tokens
  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. Its docs/ and tests/ become the version's documentation and tests, so bring them up to date in the feature first, and run its tests against
• open_source ~441 tokens
  Publish a lambda's source code at /source/{publicKey} for anybody to read, star and download as a .NET project, change the license it is published under, or take it down. What is published is the program and what is written about it - every version's code, resources, documentation and tests, and the
• platform_guide ~103 tokens
  How this platform works - read it first: what a version, a feature and data are and how long each lives, what is code and what is a resource, the documentation and tests every version keeps, what the snippet returns, what is imported, what is refused, limits and terms.
• read_database ~344 tokens
  The lambda's database - its records, shared by every version: whether it is switched on, how full it is, and its tables and views with their columns and how many rows each holds. With table, a page of that table's rows, newest first, up to 100 at a time. Read only: the lambda writes it, through Data
• read_lambda ~458 tokens
  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 for and changed, its data (the database, the workspace and the secrets: whether each is on, what it holds, and which secrets the code reads
• read_logs ~304 tokens
  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 much traffic it has had in the last hour and day. With feature, what that feature's preview has been doing instead, kept apart from the lambda'
• set_secret ~357 tokens
  Store an API key, password or token under a name the code reads with Secret.Read("NAME") - never put one in the code, a resource, the workspace, a log line or a note. The value is sealed and can never be read back, by you or the owner; only the lambda reads it, from its next call on, without a deplo
• showcase ~338 tokens
  List a lambda on the public showcase page, change its entry, or take it off. Not part of building: only do this when the user asks for it. With only privateKey it returns the current entry. An entry needs a title, a description and a picture (a screenshot or short GIF of the lambda in use); it is li
• update_feature ~299 tokens
  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 would undo what was saved after it branched off: bring the newer versions' changes into the feature first, then move base to the newest vers
• update_lambda ~248 tokens
  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 'Full' every section, the code, files, data, versions and logs included. Only the default: whoever opens the editor can switch for themselves, a
• upload_file Changes files · ~330 tokens
  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 the data instead, for trying things out without touching the real one. For files the lambda works with at runtime (pictures people will brow
• write_code ~1046 tokens
  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 code is every file not in resources/: its .cs files are compiled, in any folder, as in a C# project - lambda.cs returns the handler, the ot
